JQuery :: Getting The Opposite Of Event.preventDefault();?
Apr 30, 2010
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.
});
$(function(){ $('input').bind('keypress',null,b).bind('change',null,a); }); function a(){
[Code].....
this script bind both keypress and change of the text box to functions b and a. at keypress event handler if user type a char on input box the value of input box change to x and the user char discarded. In this case we expected to run the onchange (change) event because the textbox value is changed BUT this doesn't happen.
I'm using IE8 and when I pass: event.preventDefault(); I get an error message:
Webpage error details User Agent: Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.0; Trident/ 4.0; SLCC1; .NET CLR 2.0.50727; Media Center PC 5.0; .NET CLR 3.0.30729; .NET CLR 3.5.30729) Timestamp: Fri, 17 Jul 2009 20:07:41 UTC Message: Object doesn't support this property or method Line: 256 Char: 3
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..
I am using Jquery ajax in JSP and I am populating divs using the callback method of jquery ajax. To enable jquery/js for the populated divs I am using getScript() function so that the jquery methods get bind to the newly generated divs/html tags. Now when I am doing this multiple times the js file is getting loaded multiple times and the next time when I perform an event lick onclick or onchange, two ajax calls are going to the server which is causing lot of inconvenience. Now, my question is that is there any way to unbind the old js file either in the head tag or the one cached by using getScript function.
I have a page that has a box where announements can be seen. What I want is that when the page loads a div containing some announcement text should show up within this box. The divshould remain within the box for about 10 seconds, whereafter it should start sliding to the left and eventuallydisapper. Butif the user during the sliding decides to Hover or clickwithin that div then the sliding should stop andthe div should move back to its initail position (so that the whole text can be read again). The div shouldnotbegin any sliding process as long as theuser is hoveringwithin the div. Howeverif the user hover out of the div then the sliding proces should begin again.
What I'm trying to achieve is to havea annoncement to show up in this box, only for 10 seconds,whereafterit should disapper (by sliding away). However if the user wants to reads the annonuncementhe should be able to do so, by hovering that announcement. And whenthe user hasfinished reading he can just hover away and the announcement will disapper within few secounds. I have done some work here and there. I have used the slider method from jqueryui and the hover methods and the initial sliding process when the page loads, but putting them all to gether is not going good.
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.
I have a compressed/packed library that I am attempting to modernize. I would rather not have to convert it to a whitespace version by hand if possible.
Any chance on something like an "uncompresser/unpacker" tool existing?
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>
Could someone point me in the right direction for making a key function that removes one character from the beginning of a string every time it is pressed (basically the exact opposite of a backspace key)?
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.
What I am wanting to do is have my form open up a new part of the form when the previous sections are filled out. i.e name field shows, when it has content, the next field opens up for it to be filled out, and so on.
This has me completely stumped. I have a multiple select form element in my HTML document that needs to be manipulated by two different sets of context-sensitive controls. One set of controls is marked up as follows:
When I load this page into Safari (on Mac OS X) and set the style of divControls1 to "display:block," I have an enabled "Add" button, a disabled "Edit" button, and a disabled "Delete" button, just as I expected. (I monitor selections in a multiple selection element to turn the buttons on and off.) But when I load this page into Firefox (also Mac OS X), all three buttons are disabled at startup. My page runs a function called startup() when the body fires onLoad. To try to troubleshoot the problem, I wrote this line at the beginning of the startup() function:
function startup() { alert (document.getElementById("btnAdd").disabled); ...
When I run this code in Safari, the alert returns "false" (not disabled), just as I would expect, and intended. However, the same code in Firefox (Mac OS X) returns "true" (disabled) ... but the same code in Firefox (WinXP) returns "false"!
On unload of a page, I store the current scrollbar position (ie, window.pageXOffset and window.pageYOffset) into a cookie. On load of that same page, I fetch the information from that cookie and scroll the window accordingly.
I used the name "remember_scrolling" for the function doing the store, and "recall_scrolling" for the function doing the fetch. (There is also a function which deletes the cookie. It is named "forget_scrolling".)
But I'm afraid that this might be wrong English, for "remember" appears to cover both storing and fetching. (I guess that "recall" and "forget" are suitably specific.)
The obvious "{store,fetch,delete}_scrolling" and "{set,get,unset}_scrolling" are so, well, *obvious* and *boring*!....
I got this problem with live() event.I have used it as follows.
$(".addressDiv span").live("mouseover", function(){ //clickable function here...... ------------------------ });
I have used the live() event to trigger the function on mouseover in the dynamically added elements. But the problem i got is that once the live event is called it takes the class of the element and stores. And when the class of that particular element is changed dynamically the live() event does not detect the new classed added dynamically, instead it takes the former class. Live() event does not update the class.
