You can use the String.prototype.replacemethod, like:
您可以使用该String.prototype.replace方法，例如：
title = title.replace("<![CDATA[", "").replace("]]>", "");
This will replace each target substring with nothing. Note that this will only replace the first occurrence of each, and would require a regular expression if you want to remove all matches.
这将用空替换每个目标子字符串。请注意，这只会替换每个匹配项的第一次出现，如果要删除所有匹配项，则需要正则表达式。

You ought to be able to do this with a regex. Maybe something like this?:
你应该能够用正则表达式来做到这一点。也许是这样的？：
var myString = "<![CDATA[A Survey of Applications of Identity-Based Cryptography in Mobile Ad-Hoc Networks]]>";
var myRegexp = /<!\[CDATA\[(.*)]]>/;
var match = myRegexp.exec(myString);
alert(match[1]);

I suggest this wider way to remove leading and trailing CDATA stuff :
我建议使用这种更广泛的方法来删除前导和尾随 CDATA 内容：
title.trim().replace(/^(\/\/\s*)?<!\[CDATA\[|(\/\/\s*)?\]\]>$/g, '')
It will also work if CDATA header and footer are commented.
如果 CDATA 页眉和页脚被注释，它也将起作用。
