Don't allow typing alphabetic characters in a <input type=number />

Question

I need to have a textbox, where, whenever typed inside should ONLY allow numbers [0-9]. I\'ve used type=\"number\" which definitely holds the client side valida

Answer 1

Try this

define javascript function

function for allowed number with decimal as below

function isNumberKey(evt) {
    var charCode = (evt.which) ? evt.which : event.keyCode;
    if (charCode != 46 && charCode > 31
    && (charCode < 48 || charCode > 57))
        return false;

    return true;
}

function for allowed only number not decimal is as below

function isNumberKey(evt) {
    var charCode = (evt.which) ? evt.which : event.keyCode;
    if ((charCode < 48 || charCode > 57))
        return false;

    return true;
}
