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 helperurl: "/manage/park/index/json/index",dataType: "json",data: function (term, page) {return {parkName: term,// search termpowerpid: "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 datafor (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 preselectedvar 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 tallerescapeMarkup: function (m) {return m;}});
2,动态改变值
$("#e_pid").attr("value", temp);$("#e_pid").trigger("change"); //动态改变值以后必须触发改变时间。否则将不会生效
