on submit of dynamically generated form, find which submit button was clicked

Question

I have multiple forms which are dynamically generated at runtime by a template engine, in order to generate an ajax request on their submission i have used the "on" method to delegate the event.

$("#friendRequestsList").on("submit", "[id^=friendReqResponse-form]", function(){
    var form = this;
    $(form).ajaxSubmit({
        url:'URL',
        type:'post',
        dataType: 'json',
        success: function(data) {
            DO SOMETHING
        }

    });
    return false;
});

The form has 2 submit buttons, and i need to detect which of them was clicked and pass this information to the ajax request. However i am having a hard time knowing which of the submit inputs in the form was clicked, as they have also been dynamically generated. Ideas?

Answer 1

I hope it will help you :

$("#friendRequestsList").on("submit", "[id^=friendReqResponse-form]", function(){
     var submit1 = $(this).attr('value');

     var formData = new FormData();
     formData.append('submit1', submit1);

     $.ajax({
        url:'URL',
        type:'post',
        data:formData,
        dataType: 'json',
        success: function(data) {
            DO SOMETHING
        }

    });
    return false;
});

Answer 2

following Connors suggestion of using the click event instead of submit, i have managed to get the the submit button like so:

 $("#friendRequestsList").on("click", "[id^=submit1], [id^=submit2]", function(e) {
    var input = this;
    var form = $(input).parent();

    $(form).ajaxSubmit({
        url:'URL',
        type:'post',
        dataType: 'json',
        success: function(data) {
            DO SOMETHING
        }

    });
    e.preventDefault()
});

of course, this wouldn't work so well if my form had input fields as it wouldn't be triggered on a form submission from a keypress Enter. Also, you still need to append the input identifiying info to the ajax request.

I did this by adding

 data: {submit:input.value},

to the ajaxSubmit settings
