*This was wrong, read the one bellow :(*

Replace

<input type="Submit" name="Submit" value="Save" onClick="window.location.href='save_button.php'" >

with

<input type="button" name="Save" value="Save" onClick="window.location.href='save_button.php'" >

What this creates is a button that does not submit the form just sends the user 2 the right page

Its not working. When i click on submit button or save button it goes to the assigned page if i have not entered the values. It shows that this values are compulsary but than it goes to the another page...

Even I want to show "are you sure" when people click on submit button

so i think in submit button following thing shuld happen
1)First should check validation
2)Second should ask "are you sure"
3)Third goes to the assigned page.

Try to help me out

Soz ill try that again
replace

<form id="loginForm" name="loginForm" method="post" action="" onsubmit="return validate(this);">

The action will be changed by our javascript then submitted,
Now change your buttons

<input type="Submit" name="Submit" value="Save">
<input type="Submit" name="Submit" value="Submit" >

With

<input type="button" name="Submit" value="Save" onclick="document.loginForm.action = 'save.php';  document.loginForm.submit();">
<input type="button" name="Submit" value="Submit" onclick="document.loginForm.action = 'submit.php';  document.loginForm.submit();" >

What happens is when they click save it changes the action to save.php and submits, the other changes the action to submit.php and submits. This means the form data will be sent to both pages.

I tested this and it worked fine. If you have 2 submit buttons without changing the action it will submit to the same place whatever you do

Onclick and Onsubmit together
