Hi,

I wanted to know how to restrict value of a field using javascript.  For example, if I want LENGTH field to have only value as either 10, 20 or 30 I use below javascript code -

Element attribute as -

onchange="javascript:Check_Value(this);"

Javascript code as -

function Check_Value(pThis) {
   var myvalue = $(pThis).val();
   if (myvalue == "10" || myvalue == "20" || myvalue == "30" ) {
   }
   else
   {
     alert("Invalid value");
     return false;
   }
}

However, it will only alert me if value is not as expected, but still continues to next field.  I wanted to know, how to restrict my control to same field unless the proper value is given?  Please help.

Thanks,
