提问by Ben McCormack

I'm trying to find the following node within a page:

我正在尝试在页面中找到以下节点:

<span class="dotted">Admin</span>

I've tried the following jQuery selectors, but neither seem to work in selecting the node:

我尝试了以下 jQuery 选择器,但似乎都无法选择节点:

$(".dotted span:contains('Admin')").css("color","red");
$("span:contains('Admin') .dotted").css("color","red");

What am I doing wrong?

我究竟做错了什么?

回答by John Hartsock

This selector should do what you want.

这个选择器应该做你想做的。

$("span.dotted:contains('Admin')")

Remember you can chain Tag names with IDs and classes. Example

请记住,您可以将标签名称与 ID 和类链接在一起。例子

$("span#yourID")

OR

或者

$("span.yourclass")

OR a mixture of the two

或两者的混合

$("span#yourID.yourClass")
