We usually use input type submit for our forms to submit data to sime script.
What is the drawback of it ?
Answer : Soem of the fields may be empty but form is submitted.
How to check before submitting?
Answer:
for example you have form with one field and one submit button
then you must set the form name in form tag as name=f1and,
instead of setting type to submit set type of the button to button
and grab the information in onclick event as following.
| CODE |
<form name=f1 method=post>
Enter your name <input type=text name=n>
<input type=button value='GO'
onclick="if(f1.n.value.length==0) alert('nme empty'); else f1.submit();"
>
</form>

now save the file as test.html, put this code in and response back if any error.
