How do i use javascript validation for jsp page?
this is the validation code i have but when i change value in texbox, it wont submit:

<form name=&quot;add&quot; method=&quot;post&quot; action=&quot;/GSTS/servlet/com.fidelity.gift.gsts.servlet.GSTSControllerServlet&quot;>


<SCRIPT LANGUAGE=&quot;JavaScript&quot;>
function validate_Form()
{

var bid = window.document.add.bid.value;
if(bid == (&quot;&quot)
{alert(&quot;Please enter bid price&quot;
add.bid.select();
add.bid.focus();
return false;
}
else if(isNaN(bid) == true)
{alert(&quot;Please enter a correct bid price&quot;
add.bid.select();
add.bid.focus();
return false;
}
var ask= window.document.add.ask.value;
if(ask == (&quot;&quot)
{alert(&quot;Please enter ask price&quot;
add.ask.select();
add.ask.focus();
return false;
}
else if(isNaN(ask) == true)
{alert(&quot;Please enter a correct ask price&quot;
add.ask.select();
add.ask.focus();
return false;
}
var unit= window.document.add.unit.value;
if(unit == (&quot;&quot)
{alert(&quot;Please enter unit price&quot;
add.unit.select();
add.unit.focus();
return false;
}
else if(isNaN(unit) == true)
{alert(&quot;Please enter a correct unit price&quot;
add.unit.select();
add.unit.focus();
return false;
}

}
</script>

<input type=&quot;submit&quot; value=&quot;Submit&quot; name=&quot;submit&quot; onclick=&quot;validate_Form();return false;&quot;><input type=&quot;reset&quot; value=&quot;Reset&quot; name=&quot;reset&quot;>

You might do better in javascript forum, rather than VB forum!
