我想在元素的内容中插入一个br标记，五个字符.例如，从此:

I'd like to insert a br tag five characters into the content of the element. For example, from this:

<p>qwertyuiopasdfghjklzxcvbnm</p>

对此:

<p>qwert<br />yuiopasdfghjklzxcvbnm</p>

我该如何使用jQuery?

How can I do this with jQuery?

推荐答案

用此函数简单地替换innerHTML(在document.ready()上触发):

Simply replace the innerHTML with this function (Fires on document.ready()):

$(document).ready(function() {
    $('p').html($('p').html().substring(0,5)+'<br/>'+$('p').html().substring(5));
}
);
