无法从select2搜索结果中选择结果

Question

我在我的搜索框上使用select2.我从我的网址获得结果,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.有什么我错过了或我做的任何错误.我已经包含了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","manufacturer":"Samsung","productOptions":"Color;Memory","productOptiondesc":"Graphite;32GB"},{"productName":"samsung galaxy s3","manufacturer":"Samsung","productOptions":"Color;Memory","productOptiondesc":"Silver;16GB"}]

Answer 1

您缺少结果数据的id属性.如果没有,它会使选项"无法选择".

例:

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