layui动态渲染生成select的option值

 脚本语言：设定默认值；直接拼接，然后根据返回值渲染select
// 动态渲染脚本类型下拉框
             // 1.发送ajax请求得到data
            //  2.将data渲染到页面上
     function getDataList() {
         // 请求
         $.ajax({
             type:'post',
             url: "/cd/workPlatform/tool/detail",
             success:function(response){
                 var data=response.data;
                 $('#scriptLanguage').empty();
                 var t;
                 if(data==null){
                     t='<option value="1" selected="selected">shell</option><option value="0" >damao</option><option value="2">bobo/option>'
                 }else if(data.scriptLanguage=='1'){
                     t='<option value="1" selected="selected">bobo</option><option value="0" >damao</option><option value="2">bobo/option>'

                 }else if(data.scriptLanguage=='2'){
                     t='<option value="1" selected="selected">xiaoyang</option><option value="0" >damao</option><option value="2">bobo</option>'

                 };
                 $('.scriptLanguage').append(t);
                 form.render('select');
             }
         })
     }

     $(document).ready(function () {
         getDataList();
     });

 //展示下拉框
     function showCategory(data, count) {
         $(data).each(function (i, n) {
           //  console.log(n);
             var t = "";
             for (var j = 0; j < count; ++j) {
                 t += "&nbsp;&nbsp;&nbsp";
             }
             if (n.children.length > 0) {
                 $("#toolType").append("<option value='" + n.id + "' style='font-weight: bold;'>" + t + n.categoryName + "</option>");
                 showCategory(n.children, count + 1)
             } else {
                 $("#toolType").append("<option value='" + n.id + "'>" + t + n.categoryName + "</option>");
             }
         });
         form.render('select');
     }
     $("#toolType").append("<option value=''>请选择脚本类型</option>");
     $.get("/cd/tool/category/tree.afca", {}, function (data) {
