In Firefox, there seems to be some weird issues around when the selectedIndex of a select field changes. It seems to change on hover, rather than on click. Using: setInterval(function(){console.log($('select').prop('selectedIndex'));}, 1000); I can see the selectedIndex change as I hover over different items (the items getting a blue background and white text as I hover over them). In Chro
在Firefox中,当select字段的selectedIndex发生更改时,似乎会出现一些奇怪的问题。 它似乎改变悬停,而不是点击。 使用: setInterval(function(){console.log($('select').prop('selectedIndex'));}, 1000); 当我将鼠标悬停在不同的项目上时,我可以看到selectedIndex变化(当我将鼠标悬停在它们上方时 ,项目变为蓝色背景和白色文本)。 在Chrome中, selectedIndex仅在单击某个选项时才会更改。 我想不出一种方法来
I've been trying to get a scroll to div id jquery code to work correctly. Based on another stack overflow question i tried the following DEMO http://jsfiddle.net/kevinPHPkevin/8tLdq/ $('#myButton').click(function() { $.scrollTo($('#myDiv'), 1000); }); But it didn't work. It just snaps to the div. I also tried $('#myButton').click(function(event) { event.preventDefault();
我一直试图让滚动div ID jQuery代码才能正常工作。 基于另一个堆栈溢出问题,我尝试了以下 DEMO http://jsfiddle.net/kevinPHPkevin/8tLdq/ $('#myButton').click(function() { $.scrollTo($('#myDiv'), 1000); }); 但它没有奏效。 它只是捕捉到div。 我也试过了 $('#myButton').click(function(event) { event.preventDefault(); $.scrollTo($('#myDiv'), 1000); }); 没有进展。 你需要动画html, body
I have a couple of hyperlinks on my page. A FAQ that users will read when they visit my help section. Using Anchor links, I can make the page scroll towards the anchor and guide the users there. Is there a way to make that scrolling smooth? But notice that he's using a custom JavaScript library. Maybe jQuery offers somethings like this baked in? Update April 2018: There's now a
我的网页上有几个超链接。 用户在访问我的帮助部分时会阅读的常见问题解答。 使用锚链接,我可以使页面向锚点滚动并引导用户。 有没有办法让滚动顺畅? 但请注意他正在使用自定义JavaScript库。 也许jQuery提供这样的东西烤出来? 2018年4月更新:现在有一种本地方式可以做到这一点: document.querySelectorAll('a[href^="#"]').forEach(anchor => { anchor.addEventListener('click', function (e) {
I'm using the scrollTo jQuery plugin and would like to know if it is somehow possible to temporarily disable scrolling on the window element through Javascript? The reason I'd like to disable scrolling is that when you scroll while scrollTo is animating, it gets really ugly ;) Of course, I could do a $("body").css("overflow", "hidden"); and then put it ba
我正在使用scrollTo jQuery插件,并想知道是否有可能通过Javascript临时禁用窗口元素的滚动功能? 我想禁用滚动的原因是,当scrollTo进行动画处理时,如果进行滚动,它会变得非常难看;) 当然,我可以做一个$("body").css("overflow", "hidden"); 然后在动画停止时将其恢复为自动,但如果滚动条仍然可见但处于非活动状态,则会更好。 scroll事件不能被取消。 但是你可以通过取消这些交互事
In my app I am polling the webserver for messages every second and displaying them in the frontend. I use setInterval to achieve this. However as long as the user stays on that page the client keeps polling the server with requests even if there is no data. The server does give an indication when no more messages are being generated by setting a variable. I thought of using this variable to c
在我的应用程序中,我每秒轮询Web服务器的消息并在前端显示它们。 我使用setInterval来实现这一点。 但是,只要用户停留在该页面上,即使没有数据,客户端也会继续使用请求轮询服务器。 当通过设置变量不再生成更多消息时,服务器会发出提示。 我想使用这个变量clearInterval并停止计时器,但没有奏效。 在这种情况下我还能使用什么? 我正在使用jQuery和Django。 这是我的代码: jquery: var refresh = setInterval(
I'm having difficulty in deciding which approach is better in terms of site performance. Either to have all required jQuery plugins in one file to be included on every page on the site OR split the plugins out to individual files and use the jQuery.getScript() method to load them as and when required. Is there any real benefit in loading the scripts asynchronously over one http request?
我很难决定哪种方法在网站性能方面更好。 要么在一个文件中包含所有必需的jQuery插件,要么将其包含在网站的每个页面上,要么将插件拆分为单个文件,并在需要时使用jQuery.getScript()方法加载它们。 通过一个http请求异步加载脚本有什么好处吗? 我的所有Javascript将被缩小和gzipped。 谢谢! 这并不是那么简单,取决于你网站上javascript的分布情况。 看看这个问题:哪个更适合JavaScript加载时间:将所有文件压
I'm loading in some html via ajax, I need an event to catch on to when the new images are loaded... becuase it's in a div and not a whole page, I can't use $(window).load(.... I've tried the following but it doesn't work: $('.banners_col img:last').load(function(){..... You need to target the results of the ajax call before inserting them in the dom. So you need to use
我通过ajax加载了一些html,我需要一个事件来追踪新图像何时加载... 因为它是在一个div而不是整个页面,我不能使用$(window).load(.... 我试过以下,但它不起作用: $('.banners_col img:last').load(function(){..... 在将它们插入到dom之前,您需要定位ajax调用的结果。 所以你需要使用jQuery提供的回调方法。 $('#load').click(function(){ // inside the handler that calls the ajax //you ajax call here
how can i get a chain of functions to execute sequentially, when one of it involves waiting for a popup window? In the authBegin function below, I am popping up a window, which returns to the authBegin function when completed. But the chaining is of course not waiting for that. How can i make it wait till the window comes back? am.authUnlessCurrent().authBegin().collectData(); var authModu

I bind two event handlers on this link: <a href='#' id='elm'>Show Alert</a> JavaScript: $(function() { $('#elm').click(_f); $('#elm').mouseover(_m); }); function _f(){alert('clicked');} function _m(){alert('mouse over');} Is there any way to get a list of all events bound on an element, in this case on element with id="elm" ?
