onclick

问题 I just want to add some client side (JQuery Javascript) validation in a web user control. I put an OnClientClick handler and the function gets called. BUT, even if I return "false", the OnClick method always get fired. What am I doing wrong ? I'm with VS 2010, targeting the 4.0 framework with JQuery 1.4.2. and JQuery UI 1.8.4. Here's a sample code : <td style="text-align:right"><asp:Button ID="btnAddSave" OnClientClick="return ValidateMail();" OnClick="btnAddSave_Click" runat="server" Text=

问题 I have a multiple select tag, and I need to write the function onclick of it's options, because I need to get the value of last clicked option, but when I wrote the following $("#multiple_select option").click(function() { var val = $(this).val(); alert(val); }); it doesn't work in IE. What is the problem? UPDATE I need exactly click event, because I wrote a function onclick event already(demo here), and I need to fix last changed element's value, which is impossible to make without click

问题 I have strange problems with my (ASP.NET) web application in Microsoft Edge. At a certain point the onclick event stops working. All buttons on the page that respond to the onclick event stop working. On the same page I have some buttons that respond to the onmousedown event and they keep working. If I refresh the page, the problem is gone. There are no errors in the console. I do not have this problem with other browsers (including IE11 under Windows 10). Did any of you experience similar

问题 I've noticed that the order of 'click' and 'change' events are different in Chrome and Firefox. See this JSFiddle for example: http://jsfiddle.net/5jz2g/3/ JavaScript: var el = $('foo'); var fn = function(e) { console.log(e.type); } el.addEvent('change', fn); el.addEvent('click', fn); In Chrome this logs: change click And in Firefox this logs: click change Is there a standard for the order of events? Which should fire first? The MDN doesn't seem to mention this and I couldn't find a thing
