Need Javascript Advice

[amerar]

Hi All,

Here is my situation: I have a form where the user can perform a
number of tasks. One of these tasks is to enter a new record. The
form has an 'onsubmit' property to validate the data if the users
enters a new record.

However, there is also a button to allow the user to 'duplicate' a
stored record. In that case, I do not want to perform the entire
validation since most of the data will be fetched from the database
behind the scene. But, when the form submits, the 'onsubmit' property
takes off and attempts to validate the form......

What is the best way to handle this? Basically different behaviors
when the form is submitted??

I'm not a good Javascript programmer, so explaining throughly would
really help.

Thanks,

Arthur

Actually, the `form' element has an intrinsic event handler attribute
for handling its `submit' event, named `onsubmit'.

However, there is also a button to allow the user to 'duplicate' a
stored record. In that case, I do not want to perform the entire
validation since most of the data will be fetched from the database
behind the scene. But, when the form submits, the 'onsubmit'

You need to find out which submit button was activated. The following
example should be self-explaining:

<script type="text/javascript">
function validate(f)
{
if (f && arguments.callee.submit.name != "duplicate")
{
// perform validation, return `false' if the result is negative
}

return true;
}
validate.submit = {};
</script>

<form ... onsubmit="return validate(this);">
...
<input type="submit" value="Submit"
onclick="validate.submit = this;">
<input type="submit" name="duplicate" value="Duplicate"
onclick="validate.submit = this;">
</form>
