Paste or write? Why javascript only? Do you expect any other means also?

Solution 1

Try this:

JavaScript

// This code will bind a method to the paste operation, and in the method filters out the invalid chars.
$('#yourelement').bind('paste', function() {
    var el = this;
    setTimeout(function() {
        el.value = el.value.replace(/\D/g, '');
    }, 0);
});

* Note: this solution is using jQuery[^]

Cheers,
Edo
