php – 无法从select2搜索结果中选择一个结果

我正在使用我的搜索框中的select2.我从我的网址获取结果,但我无法从中选择一个选项.我想使用’product.productName’作为选择后显示的文本.有没有我错过的东西,或者我所犯的任何错误.我已经包括select2.css和select2.min.js,jquery.js

function dataFormatResult(product) {
        var markup = "<table class='product-result'><tr>";

        markup += "<td class='product-info'><div class='product-title'>" +     product.productName + "</div>";
        if (product.manufacturer !== undefined) {
            markup += "<div class='product-synopsis'>" + product.manufacturer + "</div>";
        }
        else if (product.productOptions !== undefined) {
            markup += "<div class='product-synopsis'>" + product.productOptions + "</div>";
        }
        markup += "</td></tr></table>";
        return markup;
    }

    function dataFormatSelection(product) {
        return product.productName;
    }
    $(document).ready(function() {
        $("#e7").select2({
            placeholder: "Search for a product",minimumInputLength: 2,ajax: {
                url: myURL,dataType: 'json',data: function(term,page) {
                    return {
                        productname: term 
                    };
                },results: function(data,page) { 

                    return {results: data.result_object};
                }
            },formatResult: dataFormatResult,formatSelection: dataFormatSelection,dropdownCssClass: "bigdrop",escapeMarkup: function(m) {
                return m;
            } 
        });
    });

这是我的resut_object

"result_object":[{"productName":"samsung galaxy s3","manufacturer":"Samsung","productOptions":"Color;Memory","productOptiondesc":"Silver;32GB"},{"productName":"samsung salaxy s3","productOptiondesc":"Graphite;32GB"},{"productName":"samsung galaxy s3","productOptiondesc":"Silver;16GB"}]

$('#e7').select2({
                    id: function(e) { return e.productName; },});
