Question

regexp:
var s = document.getElementById(“username”).value; if s == “\ \ \ \”; var result = s.replace(/\/g,””) will be wrong? why that firebug error ?

hope to the result is equals == “”, but firebug is output:

SyntaxError { source=”with(_FirebugCommandLine){(“\ \”).replace(/(\)/g,””);\n};”, message=”unterminated string literal”, fileName=”resource://firebug_rjs/console/commandLineExposed.js”, more…}

why that? please help me?

Answer 1

\ \ is a special character. See Special Characters in Javascript.

You have to escape \.

("\\ \\").replace(/(\\)/g,"");

Should work.

BTW, what are you trying to do in your regEx match?
