Question

我尝试在执行ajax调用后向select2（多选）字段添加值。我搜索解决方案并找到这个问题： Dynamically add item to jQuery Select2 control that uses AJAX

这是我的JS：

$scope.addProjectType = function(name) {
        $http.post('/ajax/projecttype/addprojecttype', {
            name: name
        }).success(function(data, status, headers, config) {
            $("#projectTypes").select2('data', {
                id: 1, name: 'test'
            })
        });
    }

一切都很好，但在执行ajax成功功能时，这给了我错误

错误：state_id.split不是函数格式@ http://ttos2.localhost/vendor/assets/global/js/plugins.js:269:31 I＆LT; .addSelectedChoice @ http://ttos2.localhost/vendor/assets/global/plugins/select2/select2.min.js:6:54786 I＆LT; .updateSelection /＆LT; @ http://ttos2.localhost/vendor/assets/global/plugins/select2/select2.min.js:6:53377

我在这里做错了什么？

它是如何运作的......：

$scope.addProjectType = function(name) {
            $http.post('/ajax/projecttype/addprojecttype', {
                name: name
            }).success(function(data, status, headers, config) {
                $("#projectTypes").append('<option value="' + data.id + '">' + data.name + '</option>');

                // get a list of selected values if any - or create an empty array
                var selectedValues = $("#projectTypes").val();
                if (selectedValues == null) {
                    selectedValues = new Array();
                }
                selectedValues.push(data.id);   // add the newly created option to the list of selected items
                $("#projectTypes").val(selectedValues).trigger('change');   // have select2 do it's thing
            });
        }

在ajax调用之后，将值更新/添加到多个select2字段
