Javascript Regular expression error in get string between two strings

Question

I have string look like this :

"fdsgsgf.signature=xxxxx(bv)"

And i want to get xxxxx

With : var testRE = html.match(".signature=(.*)/\\(");

And when i run it i get exception that it's not valid regex.

Any idea why?

Answer 1

你需要双重转义反斜杠： ".signature=(.*)/\\\\(" 。这是一个有效的正则表达式，但它会匹配/ char。如果你不需要它，只需删除它;）

Answer 2

Some issues with your code:

• You're missing starting slash / of your regex
• Instead of .* you should better use [^(]+
• dot needs to be escaped

Modified code:

html.match(/\.signature=([^(]+)/);
