select2，一款带多选功能，样式更加好看的 select 插件。

下方记录坑，前方高能.

要用 ajax 发请求并且为 select2 赋初始值

$.ajax({

                           url : _ctx+"/basInfo/listPsinfoData",
                           data : "page=1&rows=9999&flag=1",
                           type : "post",
                           async : false,
                           success : function(msg) {$("#" + PreSeleltName + "PSCODES").empty();
                               var pscodeList = [];
                               var pscodeString = "";
                               var tempList = [];
                               var data = msg.rows;
                               for (var i in data) {var temp = data[i];
                                   var tempPscode = temp.PSCODE;
                                   var tempPsname = temp.PSNAME;
                                   if(tempPscode && tempPsname){tempList.push({id :temp.PSCODE,text :temp.PSNAME});
                                   }
                               }
                               // 初始化 select2 企业 并且 赋值到 vmData.data.PSCODELIST
                               $("#" + PreSeleltName + "PSCODES").select2({
                                   data:tempList,
                                   placeholder:'选择或搜索企业',// 默认文字提示
                                   multiple: true,// 多选
                                   allowClear: true
                               }).change(function(){pscodeList = $("#" + PreSeleltName + "PSCODES").val();
                                   for(var i in pscodeList){var pscode = pscodeList[i];
                                       if(i == 0){pscodeString = pscode;}else{pscodeString = pscodeString + ","+ pscode;}
                                   }
                                   Vue.set(vmData.data, 'PSCODELIST', pscodeString);
                               });
                           },
                       });

这样 select2 下拉列表就有了对应的值

真有这么简单??? 下方记录大坑！！
