如何使用jQuery删除前两个BR标签? [英] How to remove the first two BR tags with jquery?

问题描述

我只想使用jquery删除前两个BR标签.

<div id="system">
<BR CLEAR="ALL"><BR>// I want to remove both BR.
...

<BR>...
...
<BR>

我认为是这样的.但是我不确定.

$('#system br').remove();

有人可以告诉我该怎么做吗?

解决方案

使用 :lt() :

$('#system br:lt(2)').remove();

:lt()将基于零的整数作为其参数，因此2表示第三个元素.因此:lt(2)是选择元素小于"第3个.

I'd like to remove only the first two BR tags with jquery.

<div id="system">
<BR CLEAR="ALL"><BR>// I want to remove both BR.
...

<BR>...
...
<BR>

I assume something like this. But I am not sure.

$('#system br').remove();

Could anyone tell me how to do this please?

解决方案

Use :lt():

$('#system br:lt(2)').remove();

:lt() takes a zero-based integer as its parameter, so 2 refers to the 3rd element. So :lt(2) is select elements "less than" the 3rd.
