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; } });
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
