我在 jquery 对话框中遇到问题。它多次添加相同的项目我只想添加一个项目，但它多次添加相同的项目。

我的代码：

 $("#dialog-form").dialog({
                    autoOpen: false,
                    height: 300,
                    width: 350,
                    modal: true,
                    buttons: {
                        "Submit": function() {
                            var bValid = true;
                            allFields.removeClass("ui-state-error");
                            bValid = bValid && checkLength(productname, "Product Name", 1, 100);
                            bValid = bValid && checkLength(qty, "Qty", 1, 4);
                            bValid = bValid && checkRegexp(qty, /^[+]?[0-9]*\.?[0-9]+$/, "Qty field allows only Positive numbers");
                            bValid = bValid && checkLength(price, "Price", 1, 4);
                            bValid = bValid && checkRegexp(price, /^[+]?[0-9]*\.?[0-9]+$/, "Price field allows Only Positive numbers");
                            //                            bValid = bValid && checkRegexp(amount, /^[+]?[0-9]*\.?[0-9]+$/, "Price field allows Only Positive numbers");
                            //                        alert("itemmmm mmmmmmmmm mmmmm " + itemid)

                            if (bValid) {
                                $("#users tbody").append("<tr id='" + ++rowIndex + "'>" +

                                    "</tr>");                         
                                var n = document.getElementById("qty").value;
                                var p = document.getElementById("price").value;
                                var tmpTtl = document.getElementById("tamt").value;
                                var ttl = (parseInt(n) * parseInt(p)) + parseInt(tmpTtl);
                                document.getElementById("tamt").value = ttl;
                                $(this).dialog("close");

                            }
                        },
                        Cancel: function() {
                            $(this).dialog("close");
                        }
                    },
                    close: function() {
                        allFields.val("").removeClass("ui-state-error");
                    }
                });

                $("#create-user")
                .button()
                .click(function()
                {
                    ////alert(1);
                    $("#dialog-form").dialog("open");
                });
                $("#create-user1")
                .button()
                .click(function()
                {
                    $("#dialog-form").dialog("open");
                });

            });

            $("#create-user").click(function()
            {
                $("#dialog-form").dialog("open");
            });
