In the following script:
function txKeyPressHandler(theEvent) {
var key = theEvent.which || theEvent.keyCode;
switch (key) {
case Event.KEY_RETURN:
txIMSendMsg();
var userAgent = window.navigator.userAgent;
if (userAgent.indexOf('MSIE 6.0') == -1) theEvent.preventDefault();
break;
}}
if I take out the if clause, forcing the preventDefault to get called even
for IE6 it causes a JS error (just in IE6).
he scenario is that I want to add on onclick handler to a link. When
the onclick handler fires, I want action A to take place, which will
be a request. I want to insure that action A completes before the
click to the link retrieves the page. To do that, I would like to
issue a preventDefault(), wait for action A to complete and then
direct the browser to the page specified in the link (e.g., set
location.href="clicked_link_ref").
I just cannot find any practical information that leads me to a way to
do this. I have googled and read the O'Reilly book on JS and the JS
cookbook, as well. I haven't been able to backtrack from their
examples to a solution to my own problem.
$(".change_page").click(function(e){
e.preventDefault();
do_stuff();
});
I noticed when I click one of these links, there is an ever so slight lag on all browsers. Maybe less than half a second, but it'snoticeable.
Now, when I remove e.preventDefault() and use return false instead, everything runs a lot smoother.
jquery-1.4.2.min.js
I'm trying to use the Alt+keyCode in my web-app and want to prevent the event from bubbling up to the browser.
The following works fine in FF & Chrome, no event propagation, but fails in IE8:
$().ready(function() {
$('html').keydown(function(event) {
if (event.altKey) {
if (event.altKey && event.keyCode == 83) { // 'S'

The Yahoo! UI event library goes to extremely great lengths to solve
this problem. Their solution is very creative but uses browser
sniffing. In Safari 1.3 (and earlier?) the following example follows
the link when it should not. Does anyone know of any solutions without
browser sniffing?
<p><a id="one" href="http://www.yahoo.com">link cancelled with
e.preventDefault()</a(isn't cancelled in Safari 1.3, is cancelled in
Safari 2)</p>
<script type="text/javascript" charset="utf-8">
document.getElementById('one').addEventListener('c lick',
function(e){e.preventDefault();}, false);
</script>
I have this function which prevent the default envent of a link. So far is ok. Then the function execute some tasks and then I need TO CONTINUE with the event with something like event.continueDefault(); Can I do this?
Something like:
$('.link').live('click', function(event) {
event.preventDefault(); // STOP THE EVENT
...//EXECUTE SOME TASKS
event.continueDefault() // LET THE EVENT CONTINUE. Of course, this line doesn't work.
});
I'm using IE8 and when I pass: event.preventDefault(); I get an error
message:

I know the title is not so good, it's hard to explain the simply thing I'd like to do.In fact, I'm looking for a reverse e.preventDefault() method, something like that :
$(document).keydown(function (e){
if ( e.keyCode == 9)

I am checking if a form on a jQuery tab is changed, and if it has, the user should get a popup warning when they navigate away from the tab with the form or click any other link on the page for that matter. So I setup this code:
$('a').bind('click', function(event) {
if (formChanged == true) {
event.preventDefault()
[code]....
in the $(document).ready() function. I can see the code is executed, but the click on the link still comes through and the form is lost. I've tried .click() and .live('click') as well but that doesn't work either.
I want create a page which has animation at the bottom of that page. I use jQuery to do that. This is the way I do it
<a href="#" class="animation">Animate this</a>
And this is the jquery
$(document).ready(function() {
$('a.animation').click(function(e) {
e.preventDefault();
//animation goes here;
});
});
When I run the code, all animation run very well except the page always scroll to the top. I try to change the href attribute to javascript:void(0); but it still run like that..

The following request isn't retrieving a response when I look for it in Firebug. Any ideas why?
$function(){
//json request to flickr
$.getJSON('http://api.flickr.com/services/rest/?&method=flickr.photosets.getPhotos&api_key=71282ef5623d61a898f798c7916bed31&photoset_id=72157627882181032&format=json&jsoncallback=?'),
});
Let's say I have two images. I make one dragable. I physically move one image directly over the other. While my mouse is pressed I release it. The image underneath recognizes and gives a message indicating it's covered by the other????

View 1 Replies View RelatedI'm using some jquery in a website I'm building. Here's what I'm trying to do on one of the pages: I've got a span with some text and a button in it. When the button is clicked, it fires up a jquery click function for its class that is supposed to insert a textbox into it and take the text and put it in the textbox. The class of the button is also changed from "editButton" to "finishButton" so that the other click function fires, which is going to call a webmethod to update whatever the user entered in the database.
But, the function for the editButton class gets executed when it's clicked the next time instead. I know that the class of the button has changed because the css styles for the finishButton class are in effect. I also tried removing the clicked button and creating a new one dynamically, but that one does nothing at all; it doesn't go to either click function. The stuff in the .finishButton function is only there just so I can test whether or not that function actually runs. Whether it works or not, it shouldn't matter... I'm using Firebug so if I put a break point in there, it should hit it either way, right? And this is in an aspx page if that matters at all.
I have two functions show after the message. The first works fine. When a checkbox is clicked with the class availableProfile, its class is removed, selectedProfile added. It is then appended to anotehr list and destroyed in the original. However when i click the now moved checkbox it doesn't recognize it has the new class of selectedProfile.
$(".availableProfile").click(function(event) {
elementID = event.target.id;
elementGroup = elementID.split("__");
$(this).removeClass("availableProfile");

the below code is for a form that is validated against some external (valid.js) functions. It's my first forray into Event Delegation and stupidly (testing in FF only just now) I didn't realise that the addEventListener isn't recognised in IE. Anyone got an idea which way I should look at sorting it. I am still searching and playing around but can't seem to find the right solution.

View 7 Replies View Relatedproblem: input values not recognized in dinamicly loaded IFRAMEs
here is the thing I have a parent window that has an IFRAME
I then load a diffrent page into the IFRAME that contains an input
when I try to access - iFrm.document.all["grid_name"].value
i get an error saying that - "value is null or not an object"
I tryed checking to make sure the page is fully loaded using:
document.readyState=="complete" and it is loaded and completed
the weirdest thing is that when debugging the error I can see the value
in the debbuger and after that I get the value alerted just fine
so how come I get an error ????? Code:
My HTML looks something like the following:
<label for="myTextBox">
Name:<span style="color:red;">*</span>
<input type="text" id="myTextBox"></input>
</label>
In my document ready I have a function which runs 'on blur' of the textbox and hides the span. The following code DOESN'T work to hide the span:
$('#myTextBox').closest('span').hide();
I'm currently using the code below which does work but was wondering why the above code doesn't....
$('#myTextBox').parent().children(':first').hide();
Has anybody used <button type="submit" name="dil" value="bert">dilbert</button> and attempted to add submit validation through the submit handler and preventDefault() only to find out the element value is missing? I'm currently experiencing this problem and it's a real headache.
