How to change a text with jQuery
提问by shin
I have an h1with id of toptitlethat 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 wordwith jQuery.
我有一个动态创建的h1id toptitle，我无法更改HTML。它将有不同的标题取决于页面。现在当它是 Profile 时，我想New word用 jQuery将其更改为。
<h1 id="toptitle">Profile</h1> // Changing only when it is Profile
// to
<h1 id="toptitle">New word</h1>
Note: If the text is Profile, then change it to New word.
注意：如果文本是Profile，则将其更改为New word。

Something like this should do the trick:
像这样的事情应该可以解决问题：
$(document).ready(function() {
$('#toptitle').text(function(i, oldText) {
return oldText === 'Profil' ? 'New word' : oldText;
});
});
This only replaces the content when it is Profil. See textin the jQuery API.
这仅在内容为 时替换内容Profil。请参阅textjQuery API。

Could do it with :contains()selector as well:
也可以用:contains()选择器来做：
$('#toptitle:contains("Profil")').text("New word");

最干净
Try this for a clean approach.
试试这个干净的方法。
var $toptitle = $('#toptitle');
if ( $toptitle.text() == 'Profile' ) // No {} brackets necessary if it's just one line.
$toptitle.text('New Word');

Pretty straight forward to do:
非常直接的做法：
$(function() {
$('#toptitle').html('New word');
});
The html function accepts html as well, but its straight forward for replacing text.
html 函数也接受 html，但它直接用于替换文本。
