Could you point what is preventing this code to correctly fire a javascript function when a 2nd input box is added ?

it run fine for me. could you post some json data you get for the '../api.php/pessoas' ?
(you can use chrome, network tab and copy paste what you have in the response

The json when the page loads with the 02 input fields

{"pessoas":{"columns":["id","clb_nome","email"],"records":[[1,"teste001","teste@uol.com"],[35,"XXX","aaaaa@"],[36,"Eduardo","bbbb@"],[37,"aaa",null],[39,"zzz",null],[43,"aaa",null],[47,"aaa","xxx@"],[70,"xx1","xxx@uol.com.br"],[72,"aaa","xxx@uol.com"],[74,"aa",""],[88,"aaddd",""],[90,"yyyy","xxx@xxx"],[102,"",null],[103,"aaa",null],[104,"",null],[105,"",null]]}}

Open in new window

If I use the 2nd input field the submition function isn't fired, after a blank line is inserted in DB (I need to refresh the page to see it... acordingly with the picutre above ids 104 and 105)

	self.submit = function(e) {
		e.preventDefault();
		
        // Inclusão
        console.log("Inclusao -- 01 --- ");

        var clb_nome = $(this).find('input[name="clb_nome"]').val();
        
        var email    = $(this).find('input[name="email"]').val();

        console.log(clb_nome);
        console.log(email);
      
        console.log("Inclusao -- 02 --- ");
        
       $.post(url, {clb_nome:clb_nome, email:email}, self.update);

       console.log("Inclusao -- 03 --- ");
        
	};

look like the delegate doesn't work when we have two inputs
the following trigger the self.submit every time we modify a field and leave it
please note we don't use the previous code (last line commented)

            element.on("change", "[name]", function(event) {
                self.submit();
            });
//            element.on('submit','form',self.submit);

Open in new window

leakim971

if you really want to use the ENTER key to submit, just update the render part like this :

            self.render = function(data) {
                element.html(Handlebars.compile(template.html())(php_crud_api_transform(data)));
                $("[name]", element).on('keyup', function(event) {
                    if(event.which == 13) {
                        self.submit();
                    }
                });
            };

Open in new window

end of your code look like :

            self.render = function(data) {
                element.html(Handlebars.compile(template.html())(php_crud_api_transform(data)));
                $("[name]", element).on('keyup', function(event) {
                    if(event.which == 13) {
                        self.submit();
                    }
                });
            };

            self.update = function() {
                $.get(url, self.render);
            };

            self.post = function() {
                $.post(url, {user_id:1,category_id:1,clb_nome:""}, self.update);
            };

            element.on('click','a.edit',self.edit)
            element.on('click','a.delete',self.delete)
            self.post();
        };

refresh your page, it work fine for me
if needed, put an alert("hello") after line 108 :

                $("[name]", element).on('keyup', function(event) {
                    alert("hello"); // let me know if it don't fire when you press any key
                    if(event.which == 13) {
