Javascript替换两个字符之间的字符串中间

Question

I need to replace a string like below:

Firstname Lastname : domain\999999

into:

Firstname Lastname : 999999

How would I do this using Javascript? I'm assuming a replace between the : character and \\ character.

Thanks

Answer 1

Use String#replace method

 var str = 'Firstname Lastname : domain\\\\999999'; console.log( str.replace(/(:\\s*)[^\\\\]+\\\\/, '$1') )
