preventDefault() won't work for me

Why will this refuse to work? HTML stuff <div id="nav-bar"> <ul> <li> <span> <a href="contact.html">Contact</a> </span> </li> </ul> </div> Javascript stuff $('div#nav-bar').filter('a').click(function(event){ event.preventDefault(); }); Filter only filters what is already selected. In your case, the #nav-bar element. You need this: $('div#nav-bar a').click(function(event){ event.preventDefault(); }); oezi filter is the wrong method to use here. you should either use find to look for elements in a selection: $('div#nav-bar').find('a')... or simply combine that into one selector: $('div#nav-bar a

Form still submits on preventDefault

由 我怕爱的太早我们不能终老 提交于 2019-12-02 05:19:07
I am using jQuery to submit form data to a file in the form's action. However, when I submit the form, the browser redirects to the action (comment.php). I don't know why this is because e.preventDefault() should stop the browser's redirection. Ideally, I would like the browser to not redirect and remain on the current page (index.php). jQuery: <script type='text/javascript'> $('document').ready(function(){ $('.commentContainer').load('../writecomment.php'); $('.answerContainer').on('submit', 'form', function(e){ e.preventDefault(); var form = $(this).closest('form'); $.post($(form).attr(

If conditions false then prevent default

由 给你一囗甜甜゛ 提交于 2019-12-01 15:59:05
I have a link. When some one clicks on that I want to check some conditions before letting it work. If it's false the default action should be prevented. $(".pager-next a.active").click(function(event) { if (!a == 1) { event.preventDefault(); } }); The link should only work if a is equal to 1 . Is the above code correct. a is set to 1 if a particular condition is met. The link should only work if the condition is met. Assuming by ' should only work if a is equal to 1 ' you mean the text of the a element is equal to 1, try this: $(".pager-next a.active").click(function(event) { if ($(this).text

Opera preventDefault() on keydown event

I'm trying to embed some keybindings in my webapp, and I'm having hard times with Opera. I have this code: window.onkeydown = function(e){ var key = e.keyCode ? e.keyCode : e.charCode ? e.charCode : false; if (e.ctrlKey && key === 84) { alert("foo"); e.preventDefault(); // return false; } } It works like a charm in Firefox and Chrome, but Opera still opens new tab. Same happens with return false; . My info: Opera/9.80 (X11; Linux i686; U; en) Presto/2.7.62 Version/11.00 Marcel Korpel Opera doesn't support preventDefault on keydown , only on keypress . As you can see in this example , you

JQuery PreventDefault and IE8 clarification

由 ぐ巨炮叔叔 提交于 2019-12-01 05:12:07
问题 I have been trying to understand why sometimes IE8 doesn't like PreventDefault and why sometimes it seems to be OK (no errors). From what I have read, including here at SO is that events in jquery are normalised so preventDefault will always exist with a jQuery event. However regular javascript event bindings is when the following workaround is needed for ie8: event.preventDefault ? event.preventDefault() : event.returnValue = false Is this correct? So if you are using jQuery .click .bind .on

Any ideas why preventDefault is not working? Here's the code below . . .
