match() small problem

[robert_gsfame]

I wish to validate textbox so that anything besides numeric is not allowed

I try to use isNan but not working (don't know why) then i try to use match()

 

here is the code

var test = /[0-9]+$/;

 

if(!(mystring.match(test))

alert("wrong");}

 

when i type "1234abc" alert appear but when i type "abc1234" alert not appear

which part should be modified?

 

thx in advance

/\b[0-9]+$/;

You're probably really wanting to use an anchor to make sure that all characters in the string are digits rather than just those at the end.

 

Another alternative would be to test if any one character is not a digit.
