jQuery 1.9/2.0/2.1及其以上 on 无效的解决办法

空扰寡人 提交于 2020-03-01 23:22:32
jQuery 1.9/2.0/2.1及其以上版本无法使用live函数了,然而jQuery 1.9及其以上版本提供了on函数来代替。 如果要绑定的on方法是动态加载出来的元素,那么这样使用就是没有用的。 <script> $(document).ready(function(){ $("#div1").click(function(){ $("<div class='test'>test</div>").appendTo($("#div1")); }); $(".test").on("click",function(){ $(".test").css("background-color","pink"); }); $("#div2").bind("click",function(){ $(this).css("background-color","pink"); }); }); </script> $(document).ready(function(){ $("#div1").click(function(){ $("<div class='test'>test</div>").appendTo($("#div1")); }); $(document).on("click",".test",function(){//修改成这样的写法 $(".test").css(

jQuery的.live()和.die()

很多开发者都知道jQuery的.live()方法,他们大部分知道这个函数做什么,但是并不知道是怎么实现的,所以用的并不那么舒适。而且他们却从未听过还有解除绑定的.live()事件的.die()方法。即使你熟悉这些,但是你意识到.die()了吗? 什么是 .live() .live方法类似于.bind(),除此之外,它允许你将事件绑定到DOM元素上,可以将事件绑定到DOM中还不存在的元素上,看看下面的例子: 比方说当用户在点击链接时及想提示他们正在离开站点。 ? 1 2 3 4 5 6 $(document).ready(function() { $('a').click(function() { alert("You are now leaving this site"); return true; }); }); 注意,.click()仅仅是个实现更一般.bind()的简单方法,下面和上面的代码相当于上面的实现。 ? 1 2 3 4 5 6 $(document).ready(function() { $('a').bind('click',function() { alert("You are now leaving this site"); return true; }); }); 但是现在通过javascript添加一个链接到页面。 ? 1 $('body').append

jQuery .remove() not working for dynamic form

做~自己de王妃 提交于 2020-01-25 13:01:36
问题 I am creating a dynamic form that allows a user to add/remove text fields. While I can add text fields with no problem, I'm having difficulty removing specific text fields. Whenever I add additional text fields (say a total of 5), and try to remove any of them except for the first one (say removing field 3). All of them disappear as if the page reloaded. It's as if my jQuery code doesn't run when "Remove Field" is pressed. <form> ... <div id="answers"> <div class="form-group" id="option1">

Chromecast live duration

£可爱£侵袭症+ 提交于 2020-01-24 13:02:53
问题 I am playing a live content (SmoothStreaming) with a set duration in a Chromecast device. Although manifest has a parameter duration, Chromecast doesn't get it (duration: null). I am trying do a seek to forward but Player only seek until 20 seconds later (buffering time). Is there a way to set the duration of a live stream? Or Chromecast doesn't support live seeking? Thanks in advance 来源: https://stackoverflow.com/questions/47031243/chromecast-live-duration

Jquery applying css to load div

走远了吗. 提交于 2020-01-23 19:39:38
问题 I am having an issue applying css dynamically to a loaded div using the load() function. The html being loaded is found, and it is inserted, and I can use a close command. However the css I am trying to apply is not being registered. Everything seems to work fine minus the dynamic css. I think I may have something wrong or an incorrect function here: Jquery: $(document).ready(function() { //Find & Open $(".projectThumb").click(function(){ htmlName = $(this).find("img").attr("name"); $("

Adding jQuery live search to dynamic inputs

自古美人都是妖i 提交于 2020-01-17 03:34:46
问题 I am using the jQuery live search plugin and need to bind it to all instances of a class. My class instances may or may not be dynamic. I know I can accomplish binding it to the dynamic class instances by nesting it within a jQuery Live function, E.G $(".myLink").live(click function(){}); However, I also need the non dynamic classes to have the binding as well. How can I accomplish this without defining my liveSearch binding twice? (Once at document ready for the static elements, and once in

Sending Jcodec H264 Encoded RTMP Message to Wowza

问题 I am making screen share java based application. I am done with encoding frames into H264 using JCodec java Library. I have Picture data in Byte Buffer. How I will send these encoded frames to Wowza through rtmp client? Can Wowza recognize the H264 encoded frames, Encoded by Jcodec library? 回答1: Pretty much any of the "flash" media servers will understand h264 data in a stream. You'll need to encode your frames with baseline or main profile and then "package" the encoded bytes into flv

Flutter live streaming

☆樱花仙子☆ 提交于 2020-01-12 05:53:27
问题 I am trying to build a mobile app which streams video from the camera of the device and sends it live to a server. Also, the mobile device should be able to play live video received from the server. I am building the app in Flutter, but can't seem to find a well documented library/package in Flutter which uses HLS/RTSL/WebRTC/etc. Should I use the byte stream and make a custom solution or is there a official package I can use to do the work? Thank you in advance! 回答1: For WebRTC Please try
