jQuery触发点击第一个孩子(jQuery trigger click on first child)

jQuery触发点击第一个孩子(jQuery trigger click on first child)

我试图在文档准备就绪时调用第一个.loader子.loader的点击，但没有成功：

HTML：

<a class="loader" data-target="david-boy" title="Danny Boy-Rivera"> <span class="img"><span class="play"></span><img src="img/gallery-image1.jpg" alt="" /></span> <h2>Danny Boy</h2> </a>

更新

处理器：

$('.loader').click(function(){ var name=$(this).data("target"); callVideo(name); });

UPDATE2

所以问题是我在处理程序之前声明了:first-child动作。 我改变了他们的位置，一切都好

I'm trying to invoke a click on first .loader child when document is ready, but no success:

html:

<a class="loader" data-target="david-boy" title="Danny Boy-Rivera"> <span class="img"><span class="play"></span><img src="img/gallery-image1.jpg" alt="" /></span> <h2>Danny Boy</h2> </a>

Update

Handler:

$('.loader').click(function(){ var name=$(this).data("target"); callVideo(name); });

Update2

So the problem was that I had declared the :first-child action before the handler. I changed their places and everything ok

最满意答案

您在启动触发的“点击” 之前是否定义了处理程序？

除了我在触发器之前放置处理程序之外，下面是EXACT中与您的小提琴相同的代码

$(document).ready(function(){ $('.loader').click(function(){ alert($(this).data("target")); }); $('.loader:first-child').click(); $('.loader:first-child').css("background", "red"); });​

这将弹出您正在寻找的警报

Did you define the handler before you initiated the triggered 'click'?

Here's the EXACT same code from your fiddle except I put the handler BEFORE the trigger

$(document).ready(function(){ $('.loader').click(function(){ alert($(this).data("target")); }); $('.loader:first-child').click(); $('.loader:first-child').css("background", "red"); });​

This will pop the alert you're looking for
