1,selec2动态赋值

var temp=JSON.stringify({ id: "1|所有停车场", name: "所有停车场" });
$("#e_pid").attr("value", tempP);
 $("#e_pid").select2({
 placeholder: "查找停车场名称(多选)",
 language: "zh-CN",
 minimumInputLength: 1,
 allowClear: true,
 multiple: true,
 ajax: {
 // instead of writing the function to execute the request we use Select2's convenient helper
 url: "/manage/park/index/json/index",
 dataType: 'json',
 data: function (term, page) {
 return {
 parkName: term,// search term
 powerpid: "1"
 };
 },
 results: function (data, page) { // parse the results into the format expected by Select2.
 // since we are using custom formatting functions we do not need to alter remote JSON data
 for (var i = 0; i < data.length; i++) {
 data[i].id = data[i].id+"|"+data[i].name;
 };
 data.push({ id: "577cb125f8d2c404572413d1|无", name: "无" });
 return {
 results: data
 };
 }
 },
 initSelection: function (element, callback) {
//赋初始值
 // the input tag has a value attribute preloaded that points to a preselected movie's id
 // this function resolves that id attribute to an object that select2 can render
 // using its formatResult renderer - that way the movie name is shown preselected
 var data = [];
 var value = ""
 var str = $(element).val().split('^');
 for (var i = 0; i < str.length; i++) {
 var temp = JSON.parse(str[i]);
 value += temp.id + ",";
 data.push(temp);
 }
 ;
 value = value.substring(0, value.length - 1);
 $(element).val(value);
 callback(data);
 },
 formatSelection: function (item) {
 return item.name;//注意此处的name，要和ajax返回数组的键值一样
 }, // 选择结果中的显示
 formatResult: function (item) {
 return item.name;//注意此处的name
 },// 搜索列表中的显示
 dropdownCssClass: "bigdrop", // apply css that makes the dropdown taller
 escapeMarkup: function (m) {
 return m;
 }
 });
