如何使用jQuery更改文本 [英] How to change a text with jQuery

问题描述

我有一个动态创建的ID为toptitle的h1，但是我无法更改HTML. 根据页面的不同，标题也会有所不同.现在，当它是Profile时，我想使用jQuery将其更改为New word.

I have an h1 with id of toptitle that is dynamically created, and I am not able to change the HTML. It will have a different title depends on a page. Now when it is Profile, I want to change it to New word with jQuery.

<h1 id="toptitle">Profile</h1> // Changing only when it is Profile  
// to
<h1 id="toptitle">New word</h1>

注意:如果文本为Profile，则将其更改为New word.

Note: If the text is Profile, then change it to New word.

推荐答案

这种方法应该可以解决问题:

Something like this should do the trick:

$(document).ready(function() {
    $('#toptitle').text(function(i, oldText) {
        return oldText === 'Profil' ? 'New word' : oldText;
    });
});

仅当内容为Profil时，才替换内容.请参阅jQuery API中的 text .

This only replaces the content when it is Profil. See text in the jQuery API.
