button click event is triggered after keypress using jQuery

由 被刻印的时光 ゝ 提交于 2019-12-10 19:01:36
问题 I have these codes $('#search-button').keypress(function (e) { if ((e.which && e.which == 13) || (e.keyCode && e.keyCode == 13)) { search(); }; }); $('#search-button').bind('click', function () { search(); }); under the search module I have an alert, now whenever I press Enter when the button is in focus, the search() under the click event also triggers. Please help. Thanks. 回答1: Pressing enter does fire the keypress event - but also triggers the button's 'click' event, so you get search

Invoke a ContextMenu to open

由 我只是一个虾纸丫 提交于 2019-12-10 17:57:15
问题 I need to do something like Google Maps does (but in WPF ): when RightClick on the map I have a ContextMenu. when RightDoubleClicking I have the UnZoom action. So, apparently, this is a little difficult in WPF... After struggling and searching a lot, read people that compains that "we can't predict the future" (I ask myself how does Google predict it), I decided to "wait" SystemInformation.DoubleClickTime and only then display a contextMenu. Surely, this is not ideal, even human-observable,

displaying # views on a page without hitting database all the time

由 萝らか妹 提交于 2019-12-10 17:49:39
问题 More and more sites are displaying the number of views (and clicks like on dzone.com) certain pages receive. What is the best practice for keeping track of view #'s without hitting the database every load? I have a bunch of potential ideas on how to do this in my head but none of them seem viable. Thanks, first time user. 回答1: I would try the database approach first - returning the value of an autoincrement counter should be a fairly cheap operation so you might be surprised. Even keeping a

angular bootstrap popover hide after few seconds

问题 This is my html code: <li class="pop" popover="popover text goes here" popover-trigger="mousedown"> <a><i class="icon-link"></i></a> </li> When clicking the icon a popover is opened as expected. Currenly the popover is close only by click on the icon. I wish that the popover will be closed automaticaly after few seconds. This is my javascript code - which does not work: $('.pop').popover().click(function () { setTimeout(function () { $('.pop').popover('hide'); }, 4000); }); when running $('

移动端WEB开发，click,touch,tap事件浅析

由 ≯℡__Kan透↙ 提交于 2019-12-10 16:50:34
一、click 和 tap 比较 两者都会在点击时触发，但是在手机WEB端，click会有 200~300 ms，所以请用tap代替click作为点击事件。 singleTap和doubleTap 分别代表单次点击和双次点击。 二、关于tap的点透处理 在使用zepto框架的tap来移动设备浏览器内的点击事件，来规避click事件的延迟响应时，有可能出现点透的情况，即点击会触发非当前层的点击事件。 处理方式： （1）、 github上有一个叫做fastclick的库，它也能规避移动设备上click事件的延迟响应， https://github.com/ftlabs/fastclick 将它用script标签引入页面（该库支持AMD，于是你也可以按照AMD规范，用诸如require.js的模块加载器引入），并且在dom ready时初始化在body上，如： 然后给需要“无延迟点击”的元素绑定click事件（注意不再是绑定zepto的tap事件）即可。 当然，你也可以不在body上初始化它，而在某个dom上初始化，这样，只有这个dom和它的子元素才能享受“无延迟”的点击 实践开发中发现，当元素绑定fastclick后，click响应速度比tap还要快一点点。哈哈 （2）、为元素绑定touchend事件，并在内部加上e. preventDefault(); $demo.on(

Full Calendar event hyperlinks automatically fire in Firefox

由 六眼飞鱼酱① 提交于 2019-12-10 15:17:45
问题 I'm using Full Calendar with draggable events. I have specified a url in the event object which causes the event to link to a page. Whenever I drag an event in IE or Chrome, the click event does not fire (that's good). But it does in Firefox. There is an event called eventClick provided by Full Calendar but apparently that doesn't fire before the hyperlink redirects. Is there some way to prevent drags from firing the click event without using some jQuery hack? 回答1: The problem is with event

Mouse click vs jquery click vs dispatchEvent click

由 旧城冷巷雨未停 提交于 2019-12-10 15:06:58
问题 Can someone explain to me why actual mouse click and $('div').click() runs click event 3 times while $('div')[0].dispatchEvent(new MouseEvent('click')) runs click event only 1 time according to browser console? Here's a simple html code: <div>test</div> Here's a javascript code: $('*').click(function(e){ console.log(e); }); var c = new MouseEvent('click'); // Actual mouse click output event 3 times //$('div').click(); // output event 3 times $('div')[0].dispatchEvent(c); // output event 1

问题 To add a click event to a Button in C# code behind, I can do this Button btn = new Button; btn.Click += btn_Click; What if I have an Ellipse, which does not contain a Click? Ellipse e = new Ellipse; e.??? += e_Click; 回答1: Maybe the MouseUp event will serve your purpose. Try Ellipse ellipse = new Ellipse(); ellipse.MouseUp += ellipse_MouseUp; private void ellipse_MouseUp(object sender, MouseButtonEventArgs e) { ... } 回答2: One way to do that is make button an ellipse and attatch .Click Event
