Hi,
I use the following code to archive a "numeric-only" input:
-----------------------------------------------------------------
<code>
// Check for "numeric-only" inputs
var _check = function(s)
{
var nums = s.match( /\d+/g );
if (nums) {
return nums.join("");
}
return "";
};
// A "numeric-only" input field
var element = qx.ui.form.TextField;
element.addEventListener("input", function(e) {
var value = this.getComputedValue();
var clean = _check(value);
if (value != clean)
{
this.setValue(null); // without this, the new value is not accepted :(
this.setValue(clean);
}
}, element);
</code>
-----------------------------------------------------------------
Maybe there's a better way, but it works quite well for my purposes.
