Livequery fires click no matter where the user clicks in the document - jquery-plugins

I have replaced the traditional select/option form elements with a nifty little popup window when a triggering image is clicked. The page is for accounting purposes and so multiple line items are to be expected. I've written the javascript that will dynamically generate new line item select/option elements. When the page loads, the initial set of choices loads and the user can click on them, get a pop up with some choices, choose one and then the box closes. The move to the next choice and so on and so forth. I've added livequery to my code for those dynamic elements. However... the livequery("click"...) seems to fire no matter where the user clicks on the page. Very frustrating.
I've read on here how great "live()" is in jQuery 1.3, but I am not able to upgrade fully to jquery 1.3 because a custom JS file depends on 1.2, so using live() is out of the question, however I have invoked the livequery() plugin and I really need to understand if I'm using it correctly.
I will post partial code. There's just way too much to post all of it.
Basically, I'm searching for divs starting with "bubble" and then a number afterwards. Then run the event on each them. Only bubble1 is static, 2 and up are dynamic. Am I missing the whole usage of livequery?
>$jb('div[id^="bubble"]').each(function () {
> var divid = $jb('div[id^="bubble"]').filter(":first").attr("id");
>var pref = "bubble";
>var i = divid.substring((pref.length));
>var trigger = $jb('#trigger' + i, this);
>var popup = $jb('#pop'+ i, this).css('opacity', 0);
>var selectedoption = $jb('selectedOption' + i, this);
>var selectedtext = $jb('selectedOptionText' + i, this);
>$jb([trigger.get(0), popup.get(0)]).livequery("click",
> function () {
>//alert(i);
// code removed for brevity (just the contents of the popups)
>});

Live works by using event delegation. A click event is attached to the body, and anytime something is clicked the selector is tested against the target. If it passes the selector test it calls the function (thus simulating a click event).
You probably want something like this:
$('div[id^="bubble"]').livequery("click", function() {
var divId = $(this).attr("id");
var i = divId.substring("bubble".length);
var trigger = $("#trigger" + i, this);
var popup = $("#pop" + i, this).css("opacity", 0);
// alert(i);
}

protractor click action relies on ptor.sleep(). How can I resolve correctly?

I'm a newbie trying to not rely so much or at all on using ptor.sleep() calls, especially after the click below. The line below never gets the value (they all return Nan)unless I include the ptor.sleep(1000); call after the click() below.
I've made various attempts to make the array elem to resolve before the results of the list after clicking, wrapping the click in the function, etc, but nothing I've tried works without the sleep calls. Already read up on protractor control flow.
devCountString = parseInt(arr[i]);
Thanks for any insights, maybe something obvious I've missed so that I can remove the ptor.sleep() calls.
my spec:
describe('\n == patch List suite results == \n', function() {
// login already was done in config files, onPrepare function.
var ptor, noFilterCount;
// needed here if we turn ptor.ignoreSynchronization = false;
beforeEach(function() {
ptor = protractor.getInstance();
ptor.ignoreSynchronization = true;
browser.get('https://my.abc.com:3000/fixes');
ptor.sleep(1200);
}); //end beforeEach()
it('11 - verify filter fewer', function() {
var sevStringElm, sevString;
var applicableCount;
ptor.ignoreSynchronization = false;
ptor.sleep(500);
sevStringElm = element(by.css("input.form-control.bf-spinner"));
sevStringElm.clear();
ptor.sleep(500);
sevStringElm.sendKeys( '8' );
ptor.sleep(500);
// click on the "fewer" spinner, wrap the click to wrap the .
var fewerPromise = element(by.css("span.bf-spinner-toggle:nth-child(2)")).click();
ptor.sleep(1000);
// now get the list of clickable elements in each device card. by title
var applicableDevicesElm = element.all(by.css("[title$='Applicable\ Devices']"));
applicableDevicesElm.getText().then(function(arr) {
console.log("arr.length= "+arr.length);
for (var i = 0; i < arr.length; i++) {
devCountString = parseInt(arr[i]);
expect(devCountString).toBeLessThan( 9 );
};
});
});
Everytime an action goes to the webdriver, Protractor will put that into the flow queue as shown in the documentation. As a result, when you get to inspect your elements after the click, the queue should have resolved the dependencies and have your state ready for the finder. In any case, even if you don't want to have the implicit wrapping that Protractor does on its actions (which are always asyc), you can put a .then(function(){}) after the click and put the post click logic in that anonymous calback function.
On a side note, you should have to use ptor anymore. Use browser instead that mixes in the protractor instance capabilities. Example: browser.sleep(1000)

Kendo UI Grid Editor Complete

I have a Kendo Grid, where I have defined an Editor like this:
#(Html.Kendo().Grid(Model.Data)
.Name("GridINT")
.Editable(editable => editable
.Mode(GridEditMode.PopUp)
.TemplateName("MyTemplateName")
.Window(w => w.Width(500))
.Window(w => w.Title("My Template")))
Before I engage the editor, I bind a mouseup handler to the rows, and I tweak the style of the command button. When the editor closes, whether by Submit, Cancel, or 'X', my handler and style tweaks are gone for the affected row. I need to restore them, but I haven't found the valid event. I have bound the cancel click event like this:
$('.k-grid-cancel').bind('click', function ( e ) {
colorCommandCells();
});
but if I restore my handler/style to a grid row here, the editor's closing process undoes what I have done.
Bottom line: how can I know that the editor is finished updating the grid (which it does, as I have described, even if the editor is cancelled) and which row was the one that the editor messed with?
This is the code that colors the command cells:
function colorCommandCells() {
// This block colors the command cell according to ISNEW. It must run every time the DataBound event occurs.
var grid = $("#GridINT").data("kendoGrid");
var gridData = grid.dataSource.view();
for (var i = 0; i < gridData.length; i++) {
var currentUid = gridData[i].uid;
var currentRow = grid.table.find("tr[data-uid='" + currentUid + "']");
var editButton = $(currentRow).find(".k-grid-edit");
var aColor = gridData[i].ISNEW == 1 ? "#FFCCFF" : "transparent";
var aText = gridData[i].ISNEW == 1 ? "Add" : "Edit";
var parent = $(editButton).closest("td");
$(parent[0]).css('background-color', function () { return aColor; });
editButton[0].innerHTML = "<span class=\"k-icon k-edit\"></span>" + aText;
}
}
Basically the Grid is rebound each time after such operations, and it is good to either use delegate events attached to the tbody of the Grid or bind the events each time when the dataBound event of the Grid occurs.
There are two parts to this answer: First, when building the DataSource for the Grid, assign a function to the Sync Event.
.Events(e => e.Sync("syncGrid"))
Also, when building the Grid, assign a function to the Cancel event.
.Events(e => e.DataBound("gridIsDataBound").Cancel("cancelEditor").Edit("gridEdit"))
You have to have both, because the Sync event will fire if the popup editor is closed via "Submit" and the Cancel event will fire if the popup editor is closed via "Cancel" or "X". Both functions should call something like this, where colorACommandCell is where I restore my style values:
function closeEditor() {
var timer;
clearTimeout(timer);
timer = setTimeout(colorACommandCell, 100);
}
There is still some activity related to the Grid that occurs after the editor closes (this is what clobbers my style tweaks). I found that, if I queued up my "fixes" to wait 0.1 seconds, then they would not get overwritten. Ideally, however, I'd like to have a more certain event that fires when the Editor is REALLY finished. I don't expect to be able to trust this timer on every machine that runs my code.

JqGrid BeforeShow event of add dialog variables reset

I call the following function before the add dialog is shown; after clicking [+] on the JqGrid.
MVC Controller grid configuration
ordersGrid.ClientSideEvents.BeforeAddDialogShown = "initAddDialog";
The function makes an Ajax call to create a new order record either with or without a linking id, dependent on whether an existing order was selected when the [+] button was clicked.
The purpose is to make available the id necessary to make another Ajax call to retrieve additional linked information from another service, and to pre-populate the new record with date/time information and (where applicable) common information from an existing record.
function initAddDialog() {
var newOrderId = 0;
var newOrderLinkId = 0;
var selRow = jQuery('#clientOrderGrid').jqGrid('getGridParam', 'selrow');
var selRowData = jQuery('#clientOrderGrid').jqGrid('getRowData', selRow);
Get linking ID from selected row (if any)
var curOrderLinkId = (selRowData.OrderLinkId == null) ? 0 : selRowData.OrderLinkId;
Ajax call to create new 'Holding' Order
$.ajax({
url: '/Order/ajaxNewOrder?OrderLinkId=' + curOrderLinkId,
success: function (newOrderResponse) {
arr = newOrderResponse.split("|");
newOrderId = arr[0];
newOrderLinkId = arr[1];
},
error: function () { alert("There was an error creating an Order record"); }
});
If I break the code here using Firebug in Firefox, I can see that the variables newOrderId and newOrderLinkId have been set correctly with the id's from the newly created record, and if I hit F8 the (already displayed) dialog is populated with these //values.
If I don't break the code the dialog is displayed, but displays the values with which the variables were initialised i.e. newOrderId = 0, newOrderLinkId = 0.
$('#' + 'OrderId').val(newOrderId);
$('#' + 'OrderLinkId').val(newOrderLinkId);
$('#' + 'Stock').val(stock);
$('#' + 'SettlesTs').val(settlesTs);
$('#' + 'ReceivedTs').val(dtThis);
$('#' + 'ReceivedHHmm').val(dtTime);
I've tried calling the same function after the add dialog is shown, but get the same results.
Any thoughts as to why this is, or is there a better way of achieving the same result?
Thanks
I have taken the native add/edit dialog out of the equation and am using my own 'add' form along with the native inline editing of JqGrid. I'm sure with more research it would have been possible to find a solution, but with deadlines looming I had to find a workaround.

jQuery $.get being called multiple times...why?

I am building this slideshow, hereby a temp URL:
http://ferdy.dnsalias.com/apps/jungledragon/html/tag/96/homepage/slideshow/mostcomments
There are multiple ways to navigate, clicking the big image goes to the next image, clicking the arrows go to the next or previous image, and you can use your keyboard arrows as well. All of these events call a method loadImage (in slideshow.js).
The image loading is fine, however at the end of that routine I'm making a remote Ajax call using $.get. The purpose of this call is to count the view of that image. Here is the pseudo, snipped:
function loadImage(id,url) {
// general image loading routine
// enable loader indicator
$("#loading").show();
var imagePreloader = new Image();
imagePreloader.src = url;
loading = true;
$(imagePreloader).imagesLoaded(function() {
// load completed, hide the loading indicator
$("#loading").hide();
// set the image src, this effectively shows the image
var img = $("#bigimage img");
img.attr({ src: url, id: id });
imageStartTime = new Date().getTime();
// reset the image dimensions based upon its orientation
var wide = imagePreloader.width >= imagePreloader.height;
if (wide) {
img.addClass('wide');
img.removeClass('high');
img.removeAttr('height');
} else {
img.addClass('high');
img.removeClass('wide');
img.removeAttr('width');
}
// update thumb status
$(".photos li.active").removeClass('active');
$("#li-" + id).addClass('active');
// get the title and other attributes from the active thumb and set it on the big image
var imgTitle = $("#li-" + id + " a").attr('title');
var userID = $("#li-" + id + " a").attr('data-user_id');
var userName = $("#li-" + id + " a").attr('data-user_name');
$(".caption").fadeOut(400,function(){
$(".caption h1").html('' + imgTitle + '');
$(".caption small").html('Uploaded by ' + userName + '');
$(".caption").fadeIn();
});
// update counter
$(".counter").fadeOut(400,function() { $(".counter").text(parseInt($('.photos li.active .photo').attr('rel'))+1).fadeIn(); });
// call image view recording function
$.get(basepath + "image/" + id + "/record/human");
// loading routine completed
loading = false;
}
There is a lot of stuff in there that is not relevant. At the end you can see I am doing the $.get call. The problem is that it is triggered in very strange ways. The first time I navigate to a tumb, it is called once. The next time it is triggered twice. After that, it is triggered 2 or 3 times per navigation action, usually 3.
I figured it must be that my events return multiple elements and therefore call the loadimage routine multiple times. So I placed log statements in both the events and the loadimage routine. It turns out loadimage is called correctly, only once per click.
This means that it seems that the $.get is doing this within the context of a single call. I'm stunned.
Your problem may be:.imagesLoaded is a jQuery plug in that runs through all images on the page. If you want to attach a load event to the imagePreloader only, use
$(imagePreloader).load(function() {
...
}
Otherwise, please provide the code where you call the loadImage() function.
Update:
when clicking on a thumb That is the problem. $(".photos li a").live('click',... should only be called once on page load. Adding a click handler every time a thumb is clicked will not remove the previous handlers.
Another option is to change the code to $(".photos li a").unbind('click').live('click', ... which will remove the previously registered click handlers.

jQuery Functions need to run again after ajax is complete

I am developing a website that parses rss feeds and displays them based on category. You can view it here: http://vitaminjdesign.com/adrian
I am using tabs to display each category. The tabs use ajax to display a new set of feeds when they are clicked.
I am also using two other scripts- One called equalheights, which re-sizes all of the heights to that of the tallest item. And the other script I am using is called smart columns, which basically resize your columns so it always fills the screen.
The first problem I am having is when you click a new tab (to display feeds within that category). When a new tab is clicked, the console shows a jQuery error:
$(".block").equalHeights is not a function
[Break On This Error] $(".block").equalHeights();
The main problem is that each feed box fills up the entire screen's width (after you click on a tab), even if there are multiple feed boxes in that category.
MY GUESS - although all of the feeds (across all tabs) are loaded on pageload, when a new tab is selected, both jQuery scripts need to be run again. any ideas on how I can make this work properly?
One thing to note - I used the ajaxSuccess method for making equalHeights work on the first page...but it wont work after a tab is clicked.
My jQuery code for the tabs are below:
$(".tab_content").hide(); //Hide all content
$("ul.tabs li:first").addClass("active").show(); //Activate first tab
$(".tab_content:first").show(); //Show first tab content
$("#cities li:nth-child(1)").addClass('zebra');
$("#column li ul li:nth-child(6)").addClass('zebra1');
//On Click Event
$("ul.tabs li").click(function() {
$("ul.tabs li").removeClass("active"); //Remove any "active" class
$(this).addClass("active"); //Add "active" class to selected tab
$(".tab_content").hide(); //Hide all tab content
var activeTab = $(this).find("a").attr("href"); //Find the href attribute value to identify the active tab + content
$(activeTab).fadeIn(); //Fade in the active ID content
$(".block").equalHeights();
return false;
});
Thanks to Macy (see answer below), I have brought my jQuery script to the following: (still does not work)
$(document).ajaxSuccess(function(){
var script = document.createElement('script');
script.src = 'js/equalHeight.js';
document.body.appendChild(script);
equalHeight($(".block"));
I found some small problems in your code. I am not sure that my suggestions will solve all the problems, but I decide to describe my first results here.
1) You should remove comma before the '}'. Currently the call look like $("#column").sortable({/**/,});
2) The function equalHeight is not jQuery plugin. It is the reason why the call $(".block").equalHeights(); inside your 'click' event handler follows to the error "$(".block").equalHeights is not a function" which you described. You should change the place of the code to equalHeight($(".block")); like you use it on other places.
3) The script http://vitaminjdesign.com/adrian/js/equalHeight.js defines the function equalHeight only and not start any actions. Once be loaded it stay on the page. So you should not load it at the end of every ajax request. So I suggest to reduce the script
$(document).ajaxSuccess(function(){
var script = document.createElement('script');
script.src = 'http://vitaminjdesign.com/adrian/js/equalHeight.js';
document.body.appendChild(script);
equalHeight($(".block"));
$("a[href^='http:']:not([href*='" + window.location.host + "'])").each(function() {
$(this).attr("target", "_blank");
});
});
to
$(document).ajaxSuccess(function(){
equalHeight($(".block"));
$("a[href^='http:']:not([href*='" + window.location.host + "'])").each(function() {
$(this).attr("target", "_blank");
});
});
4) I suggest to change the code of http://vitaminjdesign.com/adrian/js/equalHeight.js from
function equalHeight(group) {
tallest = 0;
group.each(function() {
thisHeight = $(this).height();
if(thisHeight > tallest) {
tallest = thisHeight;
}
});
group.height(tallest);
}
to
function equalHeight(group) {
var tallest = 0;
group.each(function() {
var thisHeight = $(this).height();
if(thisHeight > tallest) {
tallest = thisHeight;
}
});
group.height(tallest);
}
to eliminate the usage of global variables tallest and thisHeight. I recommend you to use JSLint to verify all your JavaScript codes. I find it very helpful.
5) I recommend you to use any XHTML validator to find some small but sometime very important errors in the markup. Try this for example to see some errors. The more you follow the XHTML standards the more is the probability to have the same results of the page in different web browsers. By the way, you can dramatically reduce the number of the errors in your current code if the scripts included in the page will be in the following form
<script type="text/javascript">
//<![CDATA[
/* here is the JavaScript code */
//]]>
</script>
I didn't analysed the full code but I hope that my suggestions will solve at least some of problems which you described in your question.
Essentially, when you add a new element to the document, the equalheights script has not attached its behavior to that new element. So, the "quick fix", is probably to re-embed the equalheights script after an ajax request has completed so that it re-attaches itself to all elements on the page, including the elements you just added.
Before this line: $(".block").equalHeights(); , add a line of script which re-embeds/re-runs your equalheights script.
$.getScript('<the location of your equalHeightsScript>');
$.getScript('<the location of your smartColumnsScript>');
$(".block").equalHeights();
or
var script = document.createElement('script');
script.src = '<the location of your script>';
document.body.appendChild(script);
A better solution would be to upgrade the plugin so it takes advantage of live. However, I'm not up to that at the moment :)
Some Error Here
$("ul.tabs li").click(function() {
$("ul.tabs li").removeClass("active"); //Remove any "active" class
$(this).addClass("active"); //Add "active" class to selected tab
$(".tab_content").hide(); //Hide all tab content
.
.
.
});
Should be re-written like this
$("ul.tabs li").click(function() {
$(this).addClass("active").Siblings("li").removeClass("active");; //Remove any "active" class Add "active" class to selected tab
$(".tab_content").hide(); //Hide all tab content
.
.
.
});
I don't think you need to run the scripts again after the ajax, or at least that's not the "main" problem.
You seem to have some problems in the script smartColumn.js
Right now it seems to only operate on the ul with the id "column" ('#column'), and it is working on the one UL#column you do have, but of course your HTML has many other "columns" all of which have the class "column" ('.column') that you want it to work on as well.
Just to get the beginning of what you are trying to do, change all the selectors in smartColumn.js that say 'ul#column' to say 'ul.column' instead, and then alter the HTML so that the first "column" has a class="column" rather than an id="column".
That should solve the 100% wide columns at least.
That should solve your "Main" Problem. But there are other problems.
