Hello guys

i need validate this format ###-####### (where # is a number of course)
like
123-1234567
001-5469898
when the user fills the field

the point is i have this and doesnt work yet

[CODE]
function numerofacturacontrol(e,str){
var key = window.event ? e.keyCode : e.which;

if((key==null) //null
|| (key==0) //null
|| (key==8) //backspace
|| (key==9) //horizontal tab
//|| (key==13) //enter
|| (key==27) //scape
) return true;

var myregex = new [b]RegExp(“^(\d{3,3})+(-{1,1})?(\d{7,7})?$[/b]”,”g”);
return myregex.test(str + String.fromCharCode(key));

}
[/CODE]

how i can resolve this?

thanks for advanced

var reg = /^d{3}-d{7}$/;
if (s.match(r))
// True if s matches r
else
// Otherwise false[/CODE]

thanks for the reply

it doesnt work yet ?

[CODE]
function numerofacturacontrol(e,str){
var key = window.event ? e.keyCode : e.which;

if((key==null) //null
|| (key==0) //null
|| (key==8) //backspace
|| (key==9) //horizontal tab
//|| (key==13) //enter
|| (key==27) //scape
) return true;
[b]var myregex = new RegExp("^\d{3}-\d{7}$","g"); [/b]
return myregex.test(str + String.fromCharCode(key));
}
[/CODE]
even, i cant write nothing in the textfield

remember that the user must fill data in this format ###-####### for each character

maybe your code work, coz you gave all the number
[CODE]var s = "012-3456789";[/CODE]

regards

@Orc_ScorcherSep 27.2007 — You're calling this function on a keypress event and want to allow inputs that are not yet complete like "123-", right? Then try myregex = /^(d|$){3}(-|$)(d|$){7}/

it works!!!

but i have a correction
[CODE]
var myregex = new RegExp("^(\d|$){3}(-|$)(\d|$){7}$","g");
[/CODE]
check it that is <--- twice

regards

god bless you ?

@Orc_ScorcherSep 28.2007 — In strings you have to escape the backslash, in regexp literals you must not. But I missed the final $, that correction is correct. The "g" flag is pointless here and using new RegExp just creates a new object on each keypress which must be garbage collected. It's not terribly important because even the best typist won't manage more than 10 keystrokes per second, but if the better solution is even shorter and easier to type then you might as well use it.

Success!
