keywordnya: form no action onsubmit

Menggunakan return false; di javascript 

that you call from the submit button, you can stop the form from submitting.

Basically, you need the following HTML:

<form onsubmit="myFunction(); return false;">
<input type="submit" value="Submit">
</form>
Then the supporting javascript:

<script language="javascript"><!--
function myFunction() {
    //do stuff
}
//--></script>
If you desire, you can also have certain conditions allow the script to submit the form:

<form onSubmit="return myFunction();">
<input type="submit" value="Submit">
</form>
Paired with:

<script language="JavaScript"><!--
function myFunction() {
    //do stuff
    if (condition)
        return true;

    return false;    
}
//--></script>
