如何使用 jquery 获得精确的 div 标签匹配选择器?
How to get exact div tag matching selector using jquery?
我想获得匹配 jquery 选择器的确切标签(不是父标签)。
这是我的代码:
var tagList = $('div:contains("Hello")');
alert(tagList.length);
此选择器 returns 标签列表(长度为 4),它们都是匹配标签的父 div。
<div>
<div>
<div>
<div> Hello </div> //I want to get only this element
</div>
</div>
<div> //I also tried to get deepest children but result contains this siblings of parents too.
</div>
</div>
如何将结果减少到只有一个符合规则的元素。
这里我是用filter
的方法来检查children
,如果有没有child
,那么就是您想要的元素。

var tagList = $('div:contains("Hello")').filter(function(){
return this.children.length === 0;
});
console.log(tagList.length);

<div>
<div> Hello </div>
</div>

你可以设置一个id来识别div
var tagList = $('#hello').text();
alert(tagList.length);
