I have a user form in which a user can submit his information. As there are different feilds in the form and I want to restrict a user to enter only correct values in the feilds eg in
Zip code user can only enter numbers and cannot enter any other value. If user press any other key a message is diplayed that please enter only legal values
Can any one help me in this regard? I will be great ful to him.
Thnks in advance

Hi Numan,

This should do the trick...

Code:

function ForceInt(pField){
    var exp = /[^\d]/;
    var value = pField.value;
    if(exp.test(value)){
        alert("Please enter a numeric value");
        pField.value = value.replace(exp, "");
    }    
}

...

<input id="myInput" name="myInput" type="text" onkeyup="ForceInt(this);" />

HTH,

Chris

Ur function could be like this also:

Code:

    function NumeralsOnly(elem)
    {
        var key;
        if (window.event)
            key = window.event.keyCode;
        else if (e)
            key = e.which;
        if(key >=48 & key < 57)
            return true;
        else
            return false;
    }// NumeralsOnly

Always:),
