extract number from a string - get 13 from 'product13'

[chuck]

Hello,
I am trying to figure out how to get a number (always an int) from a
string.

so if i have something like
<input type="text" id="product13" name="product13 " onblur="return
somefunc(this); " />

then have a function
somefunc(elemen t){
//extract number from element.name and get 13 in this example
// do other stuff
}

Thanks in advance,
Chuck

I found a function to do this, so i thought i would post it
function getNo(stringNo)
{var parsedNo = "";
for(var n=0; n<stringNo.leng th; n++)
{var i = stringNo.substr ing(n,n+1);
if(i=="1"||i==" 2"||i=="3"||i== "4"||i=="5"||i= ="6"||i=="7"||i =="8"||i=="9"|| i==
"0")
parsedNo += i;
}
return parseInt(parsed No);
}

<input type="text" id="product13" name="product13 " onblur="
alert(this.id.r eplace(/\D/g,''));
">

Replaces all the non-digit characters in the id with an empty string
(essentially nothing) but returns all the digits in the id:

id="product13A1 3" ==> 1313


If you just want digits at the end:

alert(this.id.m atch(/\d+$/));

id="product13A1 3" ==> 13

Well:

<input type="text" name="product13 " onblur="somefun c(this)/>

function somefunction(el ) {
mynumber=Number (el.name.slice(-2));
}

//many ways really

return parseInt(parsed No);
}

Or, less complicated:

function somefunc(obj)
{
return obj.id.match(/\d+/)[0];
}

If the number is always at the end of the id, you can better use:

obj.id.match(/\d+$/)[0];
