使用Regular Expression在两个字符串之间获取字符串

Question

I have a string that look like this 我有一个看起来像这样的字符串

BLA BLA BLA "url_encoded_fmt_stream_map": "ABCDEFGHIJKLMN" BLA BLA BLA BLA

And i want to get the string ABCDEFGHIJKLMN,i tried to do it with REGX: 我想得到字符串ABCDEFGHIJKLMN，我试图用REGX做：

html = html.match("\"url_encoded_fmt_stream_map\": \"(.*)\"");

But it always give me an empty string.Any idea what is the problem with this method? 但它总是给我一个空字符串。任何想法这个方法有什么问题？

Answer 1

Try it without the quotes: 尝试不带引号：

html = html.match(/"url_encoded_fmt_stream_map\": \"(.*)"/);

the slashes tell javascript it is a regular expression. 斜杠告诉javascript它是一个正则表达式。
