JQuery :: Prevent Navigating Away With PreventDefault() Not Working?
Mar 24, 2011
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.
$(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 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 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 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 want to hide the p and h4 in the stories, leave the pullquote and append a button to the pullquote that says "Read more". I can do this, so far.
Clicking the button will show all the p and h4 in the story, and also hide the button. I can find the parent div.story, but I can't seem to go back down the DOM to select all the p and h4 below.
I am using O'Reilly's book on building apps with HTML, CSS, and Javascript,It uses jQuery.Chapters 4 & 5 show us how to use a database. It really works well! I'm making small changes to fit my own mobile application. I've run into one problem: The page has <li>'s to link to anchors on the same page, like this:
<li class="arrow"><a href="#dates">About</a></li>
However, I want to link to another html page. I find I'm unable to do so. The following attempts don't work; that is, clicking on them will make the row change color, but won't change the page:
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.

When I open page2.html, and click on the brnClick link, it changes the content of divclick. If I open page1.html, and then navigate to page2.html, click on the link does not work.
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>
I guess because IE once again has its own variations this works or Netscape isn't following the dom I don't know which but I was hoping this type of navigation was going to be dom compliant with the newest versions of Netscape
If you have a table with the id "bob" (I like dumb names sometimes) you should be able to navigate down the table via bob.firstChild.childNodes[1].innerHTML. This does not work in netscape but does work in IE. I find this troubling because of how much easier things would have been if it worked in both. I really just wish the browsers would become equal.
The dom specification is here (outdated I believe) http://www.w3.org/TR/1999/CR-DOM-Lev...roduction.html
Thats the specification and how it supposedly works. I am going to keep playing and figure out if maybe Netscape 'changed' it. for an example try this Code:
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.
I load an Iframe within html page contained within another page and from the hosting page I would like to scroll to a given bookmark within the page loaded within the iframe without causing it to reload. How do I do this? I have tried:
function navIContent(bm) { IContent.src=bm return }
Yahoo! has launched a beta of it's new mapping application:
http://maps.yahoo.com/beta/
It's based in Flash, but it uses JavaScript. I'm curious about one feature, though - when you pan about the map, the URL in the address bar of your browser changes to match your current location. How have they done this? I thought calling window.location.href = "etc"; would reload the page, navigating away from the current URL. Yahoo! have managed to do this without the page changing. This is a very useful technique for DHTML/AJAX/Flash technology and I'd love to know how they've done it.
I have a web application that has basic authentication turned on (IIS). What I would like to accomplish is detect whether user is navigating away from the site or simply going to the different page using JavaScript. I am aware that it is easy to detect where you came from (referrer), but I haven't been able to find a way to where you're going to. I did my fair amount of research online, but I couldn't find a solution for this.
However, my boss told me that he has seen a website that detects the fact that you're navigating away from your site. Does anyone know anything about this?
I am developing a framed site. I'd like to utilize javascript "mousevoer" to change images that are used for navigating the site. Where to find something like that?
I have a question about using embedded Google Videos on my site. Does anyone have tips for allowing user to switch between videos (5) on the same page? The caveat is that only one would be showing at a time. I imagine it would require javascript coding. If so, would you have any examples?
I am trying to display an alert message when the user is in the middle of editing and clicks accidentally on some other link.
I want to display this error message for certain link and not for others.
I thought of using 'window.onbeforeunload', parse the url to find the link that was clicked. However, when I try to use the string functions (split, substring, lastindexof, etc.) inside 'onbeforeunload', they do not work.
First, with AJAX I will get a remote web page into a string. Thus, a string will contain HTML tags and such. I will need to extract text from one <span> for which I know the ID the inner text.
Is it possible to access in this way "string variable".getElementByID() somehow?
PS: Just thinking of a proper/efficient way to extract the information from such a string. I am open to other ideas. I could load that page in IFRAME and get my access to DOM that way, yet probably it is not an eligant solution.
I have designed a data entry form in HTML. In all I have upwards of 16 data entry elements (varying from edit boxes, '<input>', drop down controls, check-boxes, etc)
I know by setting the tabIndex of every data entry element user can navigate easily with the Tab key. But, even if it is non-standard, can the navigation be done with the 'Enter' key instead (it is the users, non functional requirement)
I am doing an internship at a company and am working on an existing site. The Company wants the expanding menu to stay expanded when you click a link to go to another page while navigating. I am very new to Javascript, CSS, and html and could really use some insight or code example.
