How to check which button is clicked?

[buckbeak]

I have 2 buttons which when submit form if will perform different js function (validation).

function check(){
if save button is clicked {if (form.name.value == '') {
alert("This field cannot be blank");}

}


<form onSubmit="return check()">
2 buttons - save and delete
</form>

add a hidden field to the form. Add an onclick event handler to the two buttons which puts a value in the hidden field. When the form is received, you can detect the button clicked by the value of the hidden field
