后台传来的json数组的id值 和 前端修改的值就行整合

完整的json数组包含一个小的json数组 点击完整json数组的其他元素时小json数组返回的值也没了
**
实际上点击任何一个元素 之前的都会消失 而且心 和肝 点击后背景不会退掉**

                  var arr1 = [ { "name" : "心", "acupoint_num" : "1" }, { "name" : "肝",
                  "acupoint_num" : "2" }, { "name" : "脑袋", "acupoint_num" : "3" }, { "name" : "屁股",
                  "acupoint_num" : "4" } ];

                var retStr = ",";
                $('#xueweiList').append(
                        $(arr1).map(
                                function() {

                                }).get().join(''));
                $("#nav>ul>li").click(

                            var focus = $(this).toggleClass('h_nav_over')
                                    .hasClass('h_nav_over');
                            if (focus)
                                retStr += this.id + ',';
                            else
                                retStr = retStr.replace(',' + this.id + ',',

                            $("#xueweis").val(retStr.replace(/^,|,$/g, ''));
                        });


                /* 2-获取疾病对应穴位 */
                var arr2 = [ { "earName" : "心", "acupoint_num" : "1" }, { "earName" : "肝",
                      "acupoint_num" : "2" } ];
                var arrStr2 = '';   
                var xueweisStr = "";
                $.each(arr2, function(index2, item) { // 获取后台传来的json是数组
                    arrStr2 += "<input type='button' id='"

                $.each(arr1, function(index, item) {
                    if(arr2[index2].acupoint_num==arr1[index].acupoint_num){
                        $("#"+arr1[index].acupoint_num).css({"background-color":"#98bf21"});
                                $("#xueweis").val(xueweisStr);//直接用js返回对应的穴位值给inupt赋值

                        }
                });

                xueweisStr += arr2[index2].acupoint_num + ",";

                }); 

                $("#xueweis").val(xueweisStr);//直接用js返回对应的穴位值给inupt赋值
                var td2 = document.getElementById("xueweiTd2");
                var div2 = document.getElementById("xuewei2");
                div2.innerHTML = arrStr2;
                td2.appendChild(div2);

            });

这个是没有点击脑袋之前 小的json数组包含 1 和2 两个id 对应 心和肝

这个是点击脑袋之后 1 和2 都没有了

终于实现了 把代码贴出来 就是版面还没有弄好

给retStr 赋值，你都没有依据已经选中的内容给retStr 这个变量赋值，还是空的，你再选中肯定没有了

已经设置成 retstr 了 点击事件怎么修改

    $("#nav>ul>li").click(
                        function() {
                            var focus = $(this).toggleClass('h_nav_over')
                                    .hasClass('h_nav_over');
                            if (focus)
                                retStr += this.id + ',';
                            else
                                retStr = retStr.replace(',' + this.id + ',',

                }); 

                $("#xueweis").val(retStr);//直接用js返回对应的穴位值给inupt赋值
                var td2 = document.getElementById("xueweiTd2");
                var div2 = document.getElementById("xuewei2");
                div2.innerHTML = arrStr2;
                td2.appendChild(div2);

            });

        }
    });

}

这样改完之后 那个 id 为1 的一直去不掉
