How to call a function using


onkeypress

in a textfield. Below is the code for validation :




function isNumber(evt) {

    evt = (evt) ? evt : window.event;

    var charCode = (evt.which) ? evt.which : evt.keyCode;

    if (charCode > 31 && (charCode < 48 || charCode > 57)) {

        return false;

    }

    return true;

}

Below is the code for the textfield :


<?php echo $form->textField($model,'min_size', array('placeholder' => 'Min Sqft', 'style'=>'width:100px','onkeypress'=>'isNumber(event)')); ?>

How can i pass the value and pass the script.
