RegExr out of range for backslash in javascript

Question

i got out of range error for using \ (bakcslash) for regExr Match.. ..solution please.....!!

 if ($('.channelquickvalidte').val().match("^[a-zA-Z\s0-9, '@+&$,._!#%^*()_+=/<>\\]+$") == null)  /* Error... */

{ alert("Character between A-Z/a-z and 0-9 are allowed. Additional you can use \"''@+&,._$!#%^*()_+=<>/\\\" character"); // its working fine

Error::

SyntaxError: invalid range in character class
(5525 out of range 177)

Why bother having \s inside your character class if you also have ` ` in it? Try removing \s or move it to another position. I could imagine, that js interprets \s0 in some weird way which yields the error. — Vince

Don't put the backslash at the end of the char class, use:

match("^[a-zA-Z\s0-9, '@+&$,._!#%^*()_+=/\\<>]+$")

or

match("^[a-zA-Z\s0-9, '@+&$,._!#%^*()_+=/<>\\\\]+$")

You can reduce it to:

match("^[\w\s,'@+&$,.!#%^*()+=/\\<>]+$")

\w usualy stands for [a-zA-Z0-9_] but it depends on locale.
\s stands for any space character ie. [ \t\r\n\f], so you don't need an additional space within the car class
