Post request issue

I want to make a post request and i do like this:

        function Xxx_Click() {
            var params = new Array();
            var p1 = new Object();
            p1.Name = "id";
            p1.Value = 1; 
            params.push(p1);
            post('<%=Url.Action("Act","Ctrl")%>', params);
        }
        function post(url, params) {
            var form = document.createElement('form');
            form.action = url;
            form.method = 'POST';
            form.id = "fTest";
            for (var i = 0; i < params.length; i++) {
                var hidden = document.createElement('input');
                hidden.type = 开发者_如何学运维'hidden';
                hidden.id = params[i].Name;
                hidden.name=params[i].Name;
                hidden.value = params[i].Value;
                form.appendChild(hidden);
            }
            $('#fTest').submit();
        }

but i don't reach the server side. I want to make a classic post and not to user $.post(...), how to make it right?

I'm not sure what's causing the problem but fixing these points might do the trick:

Use the setAttribute method to set attributes.

form.setAttribute("action", url);
form.setAttribute("method", "POST");
...

Then, appendChild the form to the document. It's well possible a form has to be part of the document to be submitted within that document.

Add this to the DOM before doing the actual submit. Actually the easier way will be have a form in the DOM and set the values instead of creating a new form.
