Question

I use the following script to validate the text box to enter only numbers and (.) which means it is decimal textbox validation. It was work fine in Internet Explorer and Google Chrome. If I execute the function in FireFox I get the following Error:

Event Is not Defined.

How to solve this?

function abc(event) {

        if (event.keyCode > 47 && event.keyCode < 58) {
            return true;
        }
        if (event.keyCode == 8 || event.keyCode == 46)
        {
            return true;
        }
        return false;
    }

I call this function like this:

$('.decimalValidate').live('keypress',function(){
          var decimalid=$(this).attr("id");
          var decimalval=$('#'+decimalid).val();
          var decimalvalidate=abc(decimalval);
          if(decimalvalidate == false)
          return false;
     });

I assign this validation for text box like this:

input type="text" id="Total" class="abc"

Try this

function abc(event) {
        if(!event)
           event= window.event;

        if (event.keyCode > 47 && event.keyCode < 58) {
            return true;
        }
        if (event.keyCode == 8 || event.keyCode == 46)
        {
            return true;
        }
        return false;
    }

and

$('.decimalValidate').live('keypress',function(e){
                              var decimalid=$(this).attr("id");
                              var decimalval=$('#'+decimalid).val();
                              var decimalvalidate=abc(evt); //keypress event
                              if(decimalvalidate == false)
                              return false;
                         });
