Re: RES: [PHP-DB] input field validation
Ok...so, I'm a couple days behind...
[somewhat OT tidbit]
!isNaN(null) will also return true since null is parsed as 0.
Now, if you're going to use a String search, might as well use something
built-in that does just that.
First advantage: shorter code and smaller files.
Also, RegExp's usually (but, no always) parse faster than charAt loops.
Javascript:
function isInteger(value) {
// accepts untrimmed strings
return (/^\s*[0-9]+\s*$/).test(String(value));
}
function findInteger(value) {
return String(value).replace(/^[^0-9]*([0-9]*).*?$/, '$1');
}
Tests:
var i, j;
var funcs = [isInteger, findInteger];
var input = ['12 ', '12sds', 'fhe34', 'a12.3b', '1abc2', 99, 2.4, null];
for (i = 0; i < funcs.length; i += 1) {
for (j = 0; j < input.length; j += 1) {
document.write(funcs[i](input[j]), '; ');
}
document.write('');
}
Output:
true; false; false; false; false; true; false; false;
12; 12; 34; 12; 1; 99; 2; ;
Usage:
(integers only)
function validate() {
if (!isInteger(FormObject.input1.value)) {
alert('Please enter an integer for ...');
}
}

Re: RES: [PHP-DB] input field validation
Nope, it's not. The problem was formulated as "Integer" detection. not
numerical detection in general. isNaN will return positive for e.g. floating
point values as well. The solutions described in this thread all result in
integer-only values.
All solutions presented are still off-topic, of course...
