Question

I have a html form on my website, but people keep forgetting to fill it in completely (3 boxes to fill in).

Is their a way with html to only activate the submit button if they have filled it in completely or something similar?

Answer 1

Make a javascript function to check fields and then call that function on the onsubmit event of your form.

function validate()
{
 if(document.formname.txtbox1.value=='')
 {
   alert("enter value");
   document.formname.txtbox1.focus();
   return false;        
        }
        

and then call it onsubmit event of your form

<form name = "formname" action = "abc.php" method ="post" onsubmit="return validate()">
