Hi I have a page with a navigation menu on the left and when any link
on this menu is clicked , an Ajax get call is sent to the server and
the right side gets updated with the new page.
How I am currently doing this is by creating 2 columns, the left col
contains the navigation link and the right col contans a div named the
content which has a dojotype of dojox.layout.ContentPane.Now when the
data is received from the server, I change its content like this
dijit.byId("thecontent").setContent=data
Now when I click on the navigation link , the right side gets
displayed properly(this page has dijits and also some scripts to
handle onclick events). But firebug returns an error saying
"Tried to register widget with id==thecontent but that id is already registered"
my main dojo include looks like this:-
<script type="text/javascript" src="http://o.aolcdn.com/dojo/1.5/dojo/dojo.xd.js"djConfig="parseOnLoad:false"></script>
I do a dojo.parser.parse() in the function dojo.addOnLoad like this:-
dojo.addOnLoad(function(){
dojo.require("dijit.form.Button");
dojo.require("dijit.form.Textarea");
dojo.require("dijit.form.ValidationTextBox");
dojo.require("dojox.layout.ContentPane");
dojo.require("dijit.Editor");
dojo.addOnLoad(function(){
dojo.parser.parse();
sendgetrequest();//this initiates the xhrget request
dojo.removeClass(dojo.byId("doc3"),"hiddendiv");
}
);
})
I am also unable to run any scripts in this new loaded page. No onclick event is working, just the dijit widgets are displayed...
The error means, as Ken already said, that you are creating a dijit with an id that already exists. My guess would be that you load the AJAX content in the right panel without destroying the old right panel first.
Try calling destroyRecursive on the main dijit container in the right panel before loading the new content. Also, if you do not need to set the id of the dijit, you just might drop the id (but that would leave a memory hole because the old dijits are not destroyed).

I have javascript files defined in the <head> of both my layout decorator template and my individual pages which are decorated. When I update a thymeleaf fragment in one of my pages the javascript defined in the head of the parent page no longer works. Is there a standard way to 'refresh' these js files?
Thanks.
Additional clarification :
I have a form submitted by an ajax call which updates a table in the page. I have a Jquery onClick function targeting a button in the updated table. The javascript doesn't seem able to bind to the returned elements in the updated part of the page. I select by element class and can see that the selection works prior to the partial fragment render.
For me it is unclear what you mean by
javascript defined in the head of the parent page no longer works.
The page is created on the server. Normally it contains urls of the javascript files
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js"></script>
In this case 'refreshing' the javascript files can happen only in the client.
Check the html of the page in the client.
Are the tags as expected ?
Are there tags for all expected javascript files ?
With the browser tools (for example Google Chrom developer tools ) check that all script files are actually loaded.
If this doesnt help, it could be that the order of the script tags has changed between the first and second load. This could cause a different behaviour of the javascript executed in the browser.
EDIT :
With the initial load you bind javascript callbacks to dom elements.
You do this directly or through Jquery or other libraries.
When a new dom element is loaded, it has no callbacks bound to it, even if it has the same id as a replaced dom element.
So after the load you have to bind your callbacks again.
If you bound them 'by hand', just bind it again.
If you are using a JQuery plugin, that made the bindings, look into the code or documentation, many of them have a function for that or you can call initialization again.
Once you added new content to the DOM you need to bind again the new content.
Let's say I have a button with some class, the event in binded to the class:
<button class="someclass">Button 1</button>
<script>
var something = function() {
// do something
};
$(".someclass").on("click", something);
</script>
If I add more buttons from the same class to the DOM, they will have not have the click event binded. So once you load the new content via ajax, also remove all binding and add again (you need to remove or you will have buttons with 2 events).
$(".someclass").off("click");
$(".someclass").on("click" , something);
I've got a wicket dropdown choice, and when I select something, I want to update some components within the form. This is working fine using wicket (1.4) ajax. However, it's updating the whole form including the dropdownchoice itself. There are quite a lot of items in the dropdown list (maybe 2000) so it's not great from a performance point of view.
Here's the page hierarchy:
form (Form)
|----packageDDC (DropDownChoice)
|----pptview (RefreshingView)
|----buy (Button)
packageDDC.add(new AjaxFormComponentUpdatingBehavior("onchange") {
protected void onUpdate(AjaxRequestTarget target) {
//--snip-- update pricepoints which back up the pptview
target.addComponent(form); //ie the form
}
}
In the ajax debug window I can see all the dropdown choice options being re-sent every time
What I want to do is only update the pptview and the Button via ajax, not the contents of the dropdownchoice.
I tried adding pptview to the target, but it complains that RefreshgViews can't be updated via ajax.
I tried wrapping the pptview with an EnclosureContainer, but wicket didn't like that either (something about setRenderBodyOnly)
So I tried using an WebMarkupContainer (called 'pptcontainer') and setting pptview to be a child of that - but now the pptview is not updated. Instead it says (in Ajax debug):
"ERROR: Wicket.Ajax.Call.processComponent: Component with id [[purchaseButton2f]] was not found while trying to perform markup update. Make sure you called component.setOutputMarkupId(true) on the component whose markup you are trying to update."
"ERROR: Wicket.Ajax.Call.processComponent: Component with id [[pptcontainer2e]] was not found while trying to perform markup update. Make sure you called component.setOutputMarkupId(true) on the component whose markup you are trying to update."
well these objects definitely do have this set to true:
buy.setOutputMarkupId(true);
pptcontainer.setOutputMarkupId(true);
pptcontainer.setOutputMarkupPlaceholderTag(true);
So the page is not updated correctly.
What am I doing wrong?
The new hierarchy is:
form (Form)
|----packageDDC (DropDownChoice)
|----pptcontainer (WebMarkupContainer)
| |----pptview (RefreshingView)
|----buy (Button)
I faced same problem with popup window which content is provided by ajax call. In my case the problem was solved by changing html placeholder "wicket:container" to "div" element as proposed in this article: http://sha.nnoncarey.com/blog/archives/36
After this change generated html has correct id and wicket do not have problem to find it and replace content with AJAX response.
I have a page that collects a set of user comments on the contents of that page. New comments are added to the page by clicking a button and filling out a form that appears via a Bootstrap modal. The results are then inserted into the page via ajax. This is all working fine.
The "results" that are added to the page include another Bootstrap button/link, which looks something like this:
<a tabindex='-1' href='#' class='ajax-modal btn btn-small'
data-target='modal_my-modal' data-backdrop='true'
data-controls-modal='res-modal' data-keyboard='true'
url='/somewhere'>Click me</a>
The link looks and behaves like a button (thanks, Bootstrap!), but, when clicked, doesn't trigger the modal like it's supposed to. However, if I refresh the page in the browser so that this comment, along with the others on the page, are redrawn, the button/link now works fine.
Since the button works when the page is redrawn, I'm assuming that there is some Bootstrap initialization code that runs when the page loads and sets up all the links to do their stuff, and that I need to call this after adding my new button to the page. Is this correct, and, if so, what should I be calling to get the link properly initialized? Thanks!
Short answer: There is indeed a function that gets called when the page is drawn and that sets up the click handlers -- it's my own function that's responsible for setting up the modals. I added a call to that function after the html containing the button/link, and all's well. I'm sure there is a Bootstrap init function that gets called, but calling my own is what was needed.
I´m trying to add a click event via id to a div, so that when you click on it, it moves using effects.move, but after clicking on it the first time I want the id to be removed so that it doesn´t move anymore. So far I´ve tried using observe and stopObserving - and also removing the associated id so that it doesn´t move any more. I can´t figure out how to integrate a click event with an observe, without adding it directly to the div.
Any suggestions or relative links would be greatly appreciated!
link to jsfiddle:
http://jsfiddle.net/QN4TN/2/
Once you have set the observer removing the ID will not stop the event being handled. You should do something like this:
<div id="moveme">...</div>
<script type="text/javascript">
$('moveme').observe('click', function(ev) {
ev.stop();
ev.target.stopObserving('click');
... Call move function here ...
});
</script>
This will respond to the click by removing all the click handlers from the div (And then calling your scriptaculous code). If this is a problem, you should store the pre-bound handler and then pass that as the second parameter of the stopObserving method.
I have a task to change envelope icons on the main Activities view page (Work Place, My Work -> Activities) for every row in the grid, depending on the custom status of the row in crm 4.0. I need to do it using JavaScript. Does anybody know if there is a way to do that and where should the JavaScript code be placed? I am assuming that I need to intercept grid onLoad event, go through the grid, check the condition and flip the url of the icon. But I cannot figure out how to hook into that event...
Thanks very much!
I got several very useful advices and here is what I got so far.
1. I added SiteMap to load a custom page, instead of default one (/workplace/home_activities.aspx)
2. Here is the code of the custom page, placing onreadystatechange in the html was the only way I could get this function to run. Do not know why.
HTML>
HEAD>
TITLE>
script language="javascript" type="text/javascript">
function Run()
{
var objIframe = getIframe();
if(objIframe.readyState == "complete")
{
var docFrame = objIframe.contentWindow.document;
var grid = docFrame.getElementById("crmGrid");
var allRecords = grid.InnerGrid.AllRecords;
for(var i=0; i
function getIframe()
{
return document.getElementById("wraperActivitiesFrame");
}
/script>
/HEAD>
body >
iframe id="wraperActivitiesFrame" src="/workplace/home_activities.aspx" WIDTH="100%" HEIGHT="100%" onreadystatechange="Run()">
/HTML>
The issue I am having now is that the function does not run again when I try to page the grid. I have 2 pages of Activities; when the page loads for the first time - I have my alert boxes, but when I click on "page 2" arrow - nothing happens. Why??? What I am doing wrong?
You kinda can hook into that event. You create a "wrapper" HTML page that you load in CRM instead of the default activities grid via Sitemap. This wrapper contains a full-size IFrame in which you load the actual grid, and in the IFrame's onreadystatechange handler (for readyState == 4), you traverse the grid's DOM (jQuery might make this a little easier, but I haven't used jQuery much myself) and do whatever changes you need to do (that means the JavaScript goes within the wrapper HTML page). If you call this via setInterval and put a try-catch around it, this will even be safe against grid refreshes and browsing through the pages.
