单击“overview_table_header”类时,以下函数不会产生警报。我究竟做错了什么?
<div class='overview_table_wrapper'>
<table>
<thead>
<tr>
<th class='col_1'>
<span class='overview_table_header' data-sort='DESC'>
Contest
</span>
<span class='arrow'>></span>
</th>
<th class='col_2'>
<span class='overview_table_header' data-sort='DESC'>
Tweets
</span>
<span class='arrow'></span>
</th>
<th class='col_3'>
<span class='overview_table_header' data-sort='DESC'>
Starts
</span>
<span class='arrow'></span>
</th>
<th class='col_4'>
<span class='overview_table_header' data-sort='DESC'>
Ends
</span>
<span class='arrow'></span>
</th>
</tr>
</thead>
.js文件:
(我正在加载上面未显示的文件;其他jquery可以从这个文件中运行)
$('.overview_table_header').click(function() {
alert("clicked!");
});

1)确保页面中包含jQuery.js(在下面的代码片段之前) 2)在ready事件中添加click绑定并添加Script标签
<script type="text/javascript">
$(function(){
$('.overview_table_header').click(function() { alert("clicked!"); });
});
</script>

将此部分放在页面的标题
中<script src='https://ajax.googleapis.com/ajax/libs/jquery/1.6.1/jquery.min.js'></script>
<script>
$(document).ready(function(){
$('.overview_table_header').click(function() {
alert("clicked!");
});
});
</script>

我不知道您的代码是如何构建的,但这是一个有效的结构:

根据你提供的内容,这应该可以正常工作,但我想也许这个表也是用javascript生成的?如果是这样,您将需要使用委托方法将侦听器分配给这些span标记
<script>
$('.overview_table_wrapper').delegate('.overview_table_header','click', function() {
alert("clicked!");
});
</script>
