How can I get the id of a submitted form?

Question

JavaScript

I have multiple forms, how do I know which one was submitted?

<form action etc>
input
</form>
<form action etc>
input
</form>

here is all i have JS:

var form = document.querySelectorAll('form');
for(var i=0;i<form.length;i++){
    form[i].addEventListener('submit', validate, false);
}

function validate(){
...
};

I can't find it in target..
+ data-* can't be used..

Answer 1

It is possible, for example,
where a collection of forms is stored in document.forms , and this is the current form
