替换所有特殊字符的实例

Question

 var whatever = 'Some [b]random[/b] text in a [b]sentence.[/b]';

How can I replace every instance of [b] with <b> and every instance of [/b] with </b> in jQuery?

I was attempting to do it with regex but I couldn't get it to function properly.

Answer 1

Elegant way:

whatever = whatever.replace(/\[(\/?)b\]/g,'<$1b>');

Answer 2

With regex, it'd be:

whatever = whatever.replace(/\[b\]/g,'<b>').replace(/\[\/b\]/g,'</b>');

That'd seem to be the easiest solution

Answer 3

string.replace("[b]", "<b>");

如果失败了，如果将它上传到数据库，你可以使用PHP来使用str_replace来完成它。

Answer 4

whatever = whatever.replace(/\[b\]/g, '<br>').replace(/\[\/b\]/g, '</b>');
