Using the event click with live function leads to strange behavior when using Firefox*.
With live in Firefox, click is triggered when right-clicking also! The same does not happen in Internet Explorer 7 neither in Google Chrome.
Example:
Without live, go to demo and try right clicking
the paragraphs. A dialog menu should
appear.
With live, go to demo and try right
clicking "Click me!". Now both dialog
menu and "Another paragraph" appear.
*tested with firefox 3.5.3
As far as I know, that is a known issue (bug?). You can easily work around it by testing which button was clicked as follows:
$('a.foo').live("click", function(e) {
if (e.button == 0) { // 0 = left, 1 = middle, 2 = right
//left button was clicked
} else {
//other button was clicked (do nothing?)
//return false or e.preventDefault()
}
});
you might prefer using a switch depending on your specific requirements, but generally you would probably just want to do nothing (or or simply return) if any button other than the left button is clicked, as above:
$('a.foo').live("click", function(e) {
switch(e.button) {
case 0 : alert('Left button was clicked');break;
default: return false;
}
});
I think it's a known "bug", you could potentially query the event object after attaching the click handler ( which gets attached to the document ) and see if its a right click, otherwise manually attach the click handler after you manipulate the DOM.
After looking it up, e.button is the property you want to query:
.live('click', function(e){
if ( e.button == 2 ) return false; // exit if right clicking
// normal action
});
See my answer here: if you don't mind changing the jQuery source a bit, adding a single line in the liveHandler() works around the problem entirely.

When editing my grid, if I click outside the grid, the box I was editing is still editable. How do I get the edited cell to "complete" the edit when it looses focus?
The following code will save the current edit.
Slick.GlobalEditorLock.commitCurrentEdit();
You'll need to place this inside an event handler that you think should trigger the save. For example, if you're using the sample text editor plugin, I believe an editor-text CSS class is added to the input field that's created when you're editing a cell so something like this should work:
$('#myGrid').on('blur', 'input.editor-text', function() {
Slick.GlobalEditorLock.commitCurrentEdit();
});
I found that I needed to wrap clav's handler in a timeout:
$("#myGrid").on('blur', 'input.editor-text', function() {
window.setTimeout(function() {
if (Slick.GlobalEditorLock.isActive())
Slick.GlobalEditorLock.commitCurrentEdit();
});
});
to avoid errors like:
Uncaught NotFoundError: An attempt was made to reference a Node in a context where it does not exist.
when using the keyboard to navigate. Presumably the new blur handler fires before SlickGrid can do its own handling and this causes problems.
Unfortunately, probably due to differences in event processing, Grame's version breaks keyboard navigation in chrome.
To fix this, I added another check to only commit the edit, if the newly focused element is not another editor element within the grid (as the result of keyboard navigation):
$('#grid').on('blur.editorFocusLost', 'input.editor-text', function() {
window.setTimeout(function() {
var focusedEditor = $("#grid :focus");
if (focusedEditor.length == 0 && Slick.GlobalEditorLock.isActive()) {
Slick.GlobalEditorLock.commitCurrentEdit();
}
});
});
This seems to work in current versions of firefox, chrome and ie.
I have a problem with Dojo in Internet explorer 7/8 (this works fine in Firefox).
Basically I have a tab container with a number of tabs in it (these are dojox.layout.ContentPane's). On one of these tabs I want to have a "comments box" which would popup a dialog and ask the user to put something in. The comment is then saved by an call to the back end and I want the tab to reload to show the new comment.
The logic of my save button works something like this:
<button data-dojo-type="dijit.form.Button" type="button" data-dojo-props="iconClass:'dijitIcon dijitIconSave', showLabel: true" title="Add your comment">Add Comment
<script type="dojo/on" data-dojo-event="click" data-dojo-args="evt">
require(["dojo/dom"], function(dom)
{
var tText = dijit.byId('comment_70').get('value');
if (tText == '')
{
alert('You have not entered any comment');
return;
}
var tJSONRPC = new JSONRpcClient('JSON-RPC');
try
{
tJSONRPC.be.addComment('70', tText);
var tTab = dijit.byId('Detail_70');
tTab.refresh();
}
catch (Ex)
{
alert(Ex);
}
});
</script></button>
Does not appear to be terrible taxing (the 70 at the end is the ID so that the user can have more than one of these open at the same time, hence the tabs).
As mentioned this works fine in Firefox but not in IE 8/7, it throws an error in some of the generated code within dojo (_32.focus(); to be precise), the error message I get in the debug console is "Unexpected call to method or property access"
Try this, with your line tTab.refresh();:
setTimeout(function() { tTab.refresh(); }, 0); // whenIdle
Its nearly impossible to tell where the thrown exception comes from - you should use the developement dojo-1.M.m-src/dojo/dojo.js code so optimized function- and variable-names are expanded (along with useful commenting once you step-through-debug).
Reason for the above is to eliminate, that exception occurs while handling button onclick-focus event (refresh will tear down DOM in the tab - along with your button)
Well, I'm developing a firefox addon that reload a given set of url automatically with some modification. Its not possible to show the whole code. So, I've just copy paste the part of the code which is giving me the error.
The DOMContentLoaded event is suppose to be triggered everything a page is loaded, and it do it properly. The problem is that, if i open a new tab, then DOMContentLoaded event is not triggered in the old tab.
//Any code here runs only for the first time u start the browser
window.addEventListener("load", function() { myExtension.init(); }, false);
var myExtension = {
init: function()
{
var appcontent = document.getElementById("appcontent");
if(appcontent)
appcontent.addEventListener("DOMContentLoaded", myExtension.onPageLoad, true);
},
onPageLoad: function(aEvent)
{
var doc = aEvent.originalTarget; // doc is document triggered "onload" event
//execute on one the top page (not on iframes)
if ((aEvent.originalTarget.nodeName == '#document') && (aEvent.originalTarget.defaultView.location.href == gBrowser.currentURI.spec))
{setTimeout(function(){showInError(doc.location='about:home'}, 500);}
},
}
I'd like to write the problem in a simple way (sorry for my bad English)
1) i run firefox, and the tab (say tab no.1) is continuously reloaded as i want.
2) the tab no.1 page continues to load repeatedly if i leave the page uninterrupted(that's what it want)
3) if i open a new tab (say tab no. 2), the new tab (tab no. 2) begins to reload continuously as i wanted. However, the tab no. 1 stops reloading.
what i want is to to keep on reloading both tab no 1 and tab no. 2. How to do it? what is wrong is my code?
It looks like you are executing the script only on currently displayed page (active tab).
If you want to execute it on other tabs, you should attach event listeners to new tabs as you open them (and don't forget to remove them when you close the tab). You can get useful snippets for this functionality at this page:
https://developer.mozilla.org/en/XUL_School/Intercepting_Page_Loads#WebProgressListeners
Try using gBrowser instead of document.getElementById("appcontent");
gBrowser.addEventListener("DOMContentLoaded", myExtension.onPageLoad, true);

I have a really annoying issue with Autocomplete with Prototype 1.6. I set up and dialog-style div with a form, which contains an Autocomplete. Everything works fine until I click the scroll bar, or drag it; it closes the list of suggestions. I checked this solution but now I got an javascript error
event.srcElement is undefined
I was checking the controls.js and tried to catch the event object inside the onBlur event, but it travels empty. Printed the offsetX property and is undefined. Looks like the event doesn't exist anymore. either way, it prevents that the list closes but, If I click outside the area, the list now doesn't close. And that's kinda of issue too
Anyone with this same issue? Any idea?
Thanks in advance
I was having the exact issue yesterday, but after doing some r&d I got a pretty handy fix for this.
By default this script was hiding the result div (Suggestion List) on the blur event on the search text box so as soon as we click on result div's scroll bar focus gets lost from input element & result div closes. So I did a small edit in controls.js to change the behavior of script, so now result div close method doesn't invoke on blur (focus out) from input element but triggered on the click on the document except the text input element.
For your convenience I've put the edited controls.js here.
If you like to know what has changed in JS file, here it is;
Added a event listener to the document. Just below this line
"Event.observe(this.update, "keypress", this.onKeyPress.bindAsEventListener(this));"
Event.observe($(document), "mouseup", this.onMouseup.bindAsEventListener(this));
Added a new onMouseup method.
onMouseup: function(event) {
if(!this.hasFocus) {
this.hideTimeout = setTimeout(this.hide.bind(this), 250);
this.hasFocus = false;
this.active = false;
}
},
Modify the onBlur method (Comment out two line in block)
onBlur: function(event) {
//this.hideTimeout = setTimeout(this.hide.bind(this), 250);
//this.active = false;
this.hasFocus = false;
}
I hope this will solve your issue.
Thanks

I am using HP webOS 3.0 and the Enyo framework.
I have simple question that how can I show and hide images on click of a button. I have 2 images and I want to show images on click of one button and hide on click of another button.
I have two panes called left pane and right pane on a single view.
I have around 10 items on left pane.
On each of the item click appropriate view is called on right pane.
I am doing it with following code.
showTaskView: function(){
this.$.rightPane.selectViewByName("taskView");
},
Now I want to know how can access the control's property in the main view containing both left pane and right pane.
For example,
I want to show / hide image in the taskView displayed on the right pane on click of the button that is neither in the left pane or right pane but on the header part of the view that contains both left and right pane.
It is not allowing me to access the control's image.setSrc method from the main view.
I have tried it with the following code.
editTask: function() {
this.$.task.image.setSrc("images/image2.jpg");
}
and
editTask: function() {
this.$.image.setSrc("images/image2.jpg");
}
It gives me the following error:
Cannot read property 'setSrc' of undefined
With VirtualList, your hash will only reference the currently "selected" row. "selected" being either the row receiving an event or one explicitly selected using prepareRow(). If you want to change every row, you should set a property and call refresh() on the list to cause it to rerender.
The below should work (I think ...)
setupRow: function(inSender, inIndex) {
var row = this.data[inIndex];
if (row) {
this.$.caption1.setContent("Greet a " + row.task + ":");
this.$.star.setSrc("images/grey-star.png");
if(this.hideStart) this.$.star.hide();
this.$.caption2.setContent(row.assignto);
return true;
}
},
buttonClick: function(){
this.hideStar = true;
this.$.myVirtualList.refresh();
}
