I am having some issues with a jquery on function that works in all browsers except IE.
jquery code is as follows:
$('#FormIndustryId, #FormIndustries').on("change", function () {
if ($(this).val()) {
$.getJSON('/categories/list_categories/industry_id:' + $(this).val(),
function (cats) {
if (cats !== null) {
populateCategorySelect(cats);
}
});
}
});
From a front end point of view this can be tested here: http://www.beanclaim.com/ - there is a field with the label of industry selection which is the dropdown with #FormIndustries assigned to it, it should when an industry is selected update the second dropdown with the ajax content. Chrome, Firefox and Safari it works but it seems to do nothing in IE.
Any ideas what I am doing wrong? Thanks
It's because only in IE do you have this code execute:
// IF IE (BROWSER) USE jQUERY TO SET THE PLACEHOLDER
// -------------------------------------------------->
if ( $.browser.msie ) {
$("#TemplateName").placeholder();
$("#FormIndustries").placeholder();
}
But, that returns this JS error:
SCRIPT438: Object doesn't support property or method 'placeholder'
and stops your JS from executing properly. I don't know what placeholder is (and neither does IE :) ), but if you fix that, the page works just fine in IE.
Write the same exact function, but make a copy using:
$('#FormIndustryId, #FormIndustries').on("click", ...

I am experimenting with the new way of handling page events in jqM and have run into a curious issue. When handling the pagecontainerbeforechange event
$(document).on('pagecontainerbeforechange',function(e,u){test(e,u,'changing');})
function test(e,u,msg){console.log($(u.toPage));}
Attempting to put a jQuery object wrapper around u.toPage - as done above - produces strange behavior.
Check out this fiddle to see what I mean
Click on the Second Page button and then view the console. Nothing will happen (the second page is not shown) and you will see a message along the lines of *Uncaught error:syntax error, unrecognized expression http://jsfiddle.net/egn7g5xb/1/show/#second
Now comment out Line 7 and run the fiddle again. No such issue this time and the second page gets shown.
Perhaps someone here might be able to explain what is going on here?
On initial run, jQuery Mobile creates a fake page before navigating to first page in DOM. At that stage, pagecontainerbeforechange fires twice and returns .toPage as an object.
Later on, upon navigating to other pages, it fires twice again; however, it returns a string first time (URL/hash) and second time it returns an object which is the page itself.
Therefore, when using that event, you have to determine whether .toPage is an object or a string.
$(document).on("pagecontainerbeforechange", function (e, data) {
if (typeof data.toPage == "string") {
/* parse url */
}
if (typeof data.toPage == "object") {
/* manipulate page navigating to */
}
});
Note that pagecontainerbeforetransition is similar to beforechange, however, it fires once and returns .toPage as an object.
First, create your pagecontainer events within $(document).on("pagecreate", "#first", function(){ .. }).
Then the selector for these events should be $(":mobile-pagecontainer") or $("body") NOT $(document).
function test(e,u,msg)
{
console.log(msg);
var IsJQ = u.toPage instanceof $;
console.log(IsJQ);
if (IsJQ){
console.log(u.toPage.data());
} else {
console.log(u.toPage);
}
console.log('---');
}
$(document).on("pagecreate", "#first", function(){
$(":mobile-pagecontainer").on('pagecontainerbeforechange', function (e, u) {
test(e,u,'changing');
});
$(":mobile-pagecontainer").on('pagecontainerchange',function(e,u){
test(e,u,'changed');
});
});
Updated FIDDLE
I'm using Boostrap (2.3.1) Modal to show forms (those are loaded with ajax). However, when i try to replace a textarea triggered by the "shown" event and CKEDITOR.replace(id) (CKEditor 4.2), it won't be replaced in IE 9 (Firefox & Chrome are fine).
If I set a timeout, it at least replaces the second time you call the dialog:
$("#bok-modal-form").on("shown", function() {
$(this).find(".modal-body").find(".bokCKE").each( function() {
var id = $(this).attr("id");
if( CKEDITOR.instances[id] ) CKEDITOR.instances[id].destroy(true);
window.setTimeout(function() {
CKEDITOR.replace(id);
}, 1000);
});
});
Otherwise only the second time ie debugger shows the error that "document" is not set, pointing me to the following ( # a.editable(new j(a,e.$.contentWindow.document.body)); ).
Not quite sure what I am doing wrong here?
CKEDITOR not replacing on the first time seems to be an issue with the shown event. In ie the modal-body is still empty. I surrounded the each loop with a setTimeout (300), and it seems to work (bit more testing required).
Update: that did the trick.
I am new in using jquery. I am trying add in the simplemodal.js (Eirc Martin's simple modal) a function called 'jBox' that will take the data (ie link) and options and using ajax will load the content into the modal container. This way I want on my pages in several places easy call this function
jBox = function(address, options){
$.get(address, function(data) {
$.modal(data);
});
};
});
The code is working fine, but i would like to add a loading image before the content is fully loaded. There is a lots of similar posts about loader/ spinner in simplebox but none of the works for me.
I was trying following code
$('#test').load('<img src="loader.gif">').html(data);
$('#test').modal();
But, some way, it doesnt work for me. Any ideas what I am doing wrong? Thanks
I use the ajaxStart and ajaxStop events.
$("body").on({
ajaxStart: function() {
$(this).addClass("loading"); // so page knows it's in loading state
// .. your modal code
},
ajaxStop: function() {
$(this).removeClass("loading"); // not it loading state anymore
// .. What you should do if loading is done. (eg. hide modal)
}
});
In this case I set the body class to 'loading'. So you can do some magic in css if you like.
I tend to use it to disable forms as well.
body.loading div.some-class {
// your special style for during loading
}
So i I have a page that contains links that call an httpRequest. The request calls a php file that grabs data from mysql and pre populates a form which is then returned to the browser/webpage. My problem is that when the page is returned to the browser via the httpRequest/ajax the text area does not display the tinymce editor, it just displays a normal text area. It looks like my request and ajax is working fine the text area just doesn't have the tinycme editor on it.
When i don't use ajax it works fine but when i put it in a separate file and call it via ajax it doesn't bring in the tinymce editor.
Does anyone know how to fix this problem so that my ajax generated page displays the text area with the tinymce editor. Thank you.
Lets presume that your thinyMCE instance is initialized with code below
// initialize tinyMCE in page
tinyMCE.init({
mode: "textareas",
theme: "advanced"
});
and you have some kind of button somewhere in the page. For purpose of this tip, i will not give it any ID but you may. Now, using jQuery you can easily attach event handler to that button which will call through AJAX your server and take content which you want to put tinyMCE editor. Code which will do such job would look somehow like below.
$(function() {
$("button").bind("click", function() {
var ed = tinyMCE.get('content');
ed.setProgressState(1); // Show progress
$.getJSON('/page/12.json', { /* your data */
}, function(data) {
ed.setProgressState(0); // Hide progress
ed.setContent(data["body"]);
}
});
});
});
You can see that on button.click ajax will call url /page/12.json which will return JSON as response. bare minimum of that response could be:
{
title: "Page title",
body: "<html><head><title>Page title</title>......</html>"
}
I attached anonymous function as callback which will handle response from server. and hide progress indicator which is shown before ajax call.
About JSON
JSON is shorten of JavaScript Object Notation. It is JavaScript code!!! So don't be confused about it. Using JSON you can make javascript object which can have attributes you can use later in your code to access particular peace of data which that object "holds". You can look at it as some kind of data structure if it is easier to you.
Anyway, to show you how this JSON can be created by hand look at examples below
var data = new Object();
data.title = "Page title";
data.body = "<html....";
or
var data = {
title: "page title",
body: "<html...."
};
it is very same thing.
If you want to learn more about JSON point your browser to http://json.org.
===== alternative =====
Alternative to json solution could be just plane ajax call to server and response can be plain HTML (from your question I can assume that you have something like this already). So instad of calling $.getJSON you can use $.get(url, callback); to do same thing. The code at the top of my answer will not dramatically change. Instead of geting JSON in response you will get string which is HTML.
----------- BOTTOM LINE -------
I prefer JSON since it can be easily extended later with other attributes, so there is no painful code changes later ;)
Problem here will be that when you return the full page and render it using the ajax response, your tinymce instance has not been shut down before.
In order to do this you can call this small piece of code before you render the ajax response:
tinymce.execCommand('mceRemoveControl',true,'editor_id');
In this case the editor should initialize correctly. You are not allowed to initialize a tinymce editor with the same id before shutting the first one down.
Strangely i ran into this problem yesterday. Following code should work, but YMMV. Trick is to use the correct steps in ajax events. I used the Regular TinyMCE and made use of the jQuery library already included.
Following goes into your tinyMCE initialization tinyMCE.init() . All of the below block should be outside the document.ready.
myTinyInit = {
//.......All essential keys/values ...........
setup : function(ed) {
ed.onChange.add(function( ed ) {
tinyMCE.triggerSave();
}) }
//.....................
};
// Init the tinyMCE
tinyMCE.init(myTinyInit);
This ensures the content is being saved regularly onto the textarea that holds the value. Next step is setting up the request events.
Normally tinyMCE mceAddControl before the ajax post and mceRemoveControl after the ajax success should do the trick. But I found that often does not work.
I used the form as the jQuery selector in my case.
jQuery( '.myForm' )
.find( 'textarea#myTextArea' )
.ajaxStart(function() {
// If you need to copy over the values, you can do it here.
// If you are using jQuery form plugin you can bind to form-pre-serialize event instead.
// jQuery( this ).val( tinyMCE.get( jQuery( this ).attr( 'id' )).getContent() );
}).ajaxSend( function() {
// ! - step 2
// My case was multiple editors.
myEds = tinyMCE.editors;
for( edd in myEds ) {
myEds[ eds ].remove();
}
// tinyMCE.get( 'myTextarea' ).remove();
// strangely mceRemoveControl didnt work for me.
// tinyMCE.execCommand( 'mceRemoveControl', false, jQuery( this ).attr('id'));
}).ajaxSuccess(function() {
// Now we got the form again, Let's put up tinyMCE again.
txtID = jQuery( this ).attr( 'id' );
// ! - step 3
tinyMCE.execCommand( 'mceAddControl', false, txtID );
// Restore the contents into TinyMCE.
tinyMCE.get( txtID ).setContent( jQuery( this ).val());
});
Problems i came across :
Using mceRemoveControl always gave me r is undefined error persistently.
If you get a blank tinyMCE editor, check the DOM whether the ID of the textarea is replaced with something like mce_02, this means that TinyMCE is being initialized again or something is wrong with the order. If so, the tinyMCE is duplicated with each save.
if you are new to JS, I recommend using jQuery with the form plugin, it might be easier for you. But do use the regular non-jquery tinyMCE, as it is well documented.
I fixed this problem by recalling the function after the ajax call. In this part of my ajax:
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("Content").innerHTML=xmlhttp.responseText;
tinymce();
Now it works fine.
I have a page which needs to use $.post() but for some reason the exact code works when I run it from the firebug console but not from my script? My script is:
$(document).ready(function () {
$('#dl_btn').click(function () {
$.post(
"news_csv.php",
$("#dl_form").serialize(), function (data) {
alert('error');
if (data == 'success') {
alert('Thanks for signing up to our newsletter');
window.open("<?php echo $_GET['link']; ?>");
parent.Shadowbox.close();
} else {
alert(data);
}
});
});
});
It isn't the link as that does get printed properly but it gives me an error on line 140 of jquery min, I have tried using different versions of jquery and to no avail. I really dont understand why this isn't working.
When I changed from $.post to $.ajax and used the error callback I did receive an error of 'error' and the error is undefined?
Don't suppose anyone has any ideas? Would be much appreciated.
Thanks,
Tom
Is your click button placed inside a form element?
Cause doing so, clicking on it will not only trigger the onClick event you have binded to, but form submit as well, so you will end up in a case where your browser is executing both requests in parallel - with unpredicted outcome, of course.
I tried the same code with an element that does not trigger form submit and it worked as expected.
One point though: if you plan to use simple string as a return value and to do something with it (display it or so) then is ok to do what you do right now. However, if you have more complex response from the ajax request, you should specify the response type (xml, json..) as the last parameter of the post method.
Hope this helps.
