Question

请您查看This Demo并告诉我如何循环播放<pre>之类的元素并将所有<和>替换为一些新字符像：

.replace("<", "1");
.replace(">", "2");

如果我们有<pre>喜欢

<pre>
    < This is a test < which must > replace >
</pre>

谢谢

Answer 1

您可以使用.text()

使用String.replace()和RegExp

＆＃13;

$('pre').text(function(i, text){
    return text.replace(/</g, '1').replace(/>/g, '2')
})

＆＃13;

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<pre>
    < This is a test < which must > replace >
</pre>

＆＃13;

Answer 2

可能就像

var test = $("pre").text();

var k = test.split("<").join(1).split(">").join(2);

alert(k);

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<pre>< This is a test < which must > replace ></pre>
