Question

I have written an autocomplete function.
When I click on #input3 it starts to generate what I have typed.

Example: “apple” I type “app” and I click to select “apple”. What I select should be sent to the src and updated in #input2.

Problem: What is sent to the src is what I have typed and not what I have selected. Why?

.autocomplete({
    source: function(request, response) {
        $.ajax({
            url: src,
            fillin:true,
            dataType: "json",
            data: {
                term : request.term,
                c3 : $("#input3").val()
                },
            success: function(data){
                response(data)
                }
            });
        },
    minLength: 0,
    delay: 300
    })
.change(function(request2, response) {
    $.ajax({
        url: src,
        dataType: "json",
        data: {
            term : request2.term,
            c1 : "search",
            c3: $("#input3").val()
            },
        success: function(data){
            $("#input2").val(data);
            }
        });
    })

I have solve it. I add the cod after .autocomplete

        focus: function(event, ui) {
            $("#txtBufferTwo").val(ui.item.value);
            event.preventDefault();
            },

Follow by a hidden field.

What I did was once selection was click, the value is assign to the hidden field and submit the value of the hidden field.
