javascript - 点击select框选项 弹出ngDialog 点击取消的时候 关闭弹出框 希望select框的值不变

Question

标题文字 ##下边是我的代码，点击取消后，select框的值依然会改变

//views
< select class="mei-select mei-select-md" ng-model="nextparam.emscaapportionh.imp_erp_type" ng-options="m.itemValue as m.itemName for m in impErpTypes" ng-disabled="!isErpTypeEdit" ng-change="impErpTypeChange()" > </select >

//ngDialogCtrl

(function () {
    'use strict';
    angular.module('app')
        .controller("ngDialogCtrl", ['$scope',
            function ($scope) {
                $scope.msg = $scope.dialog ? $scope.dialog.msg : '确认要执行吗？';
            }
        ]);
})();

//业务逻辑
$scope.openConfirmDialog = function (callback, msg) {
$scope.dialog = {
        msg: msg
    };
    ngDialog.openConfirm({
        template: 'app/app_common/views/ngdialog.confirm.html',
        plain: false,
        showClose: true,
        closeByDocument: true,
        closeByEscape: true,
        scope: $scope,
        width: '20%',
        controller: 'ngDialogCtrl'
    }).then(callback);
};

 //修改导ERP类型
$scope.impErpTypeChange = function () {
    var impErpTypeChangeFun = function () {
        $scope.budgetGridOptions.data = [];
    };
    $scope.openConfirmDialog(impErpTypeChangeFun, '更改导类型将会清空明细，是否继续？');
}

看了ngDialog api，加多一个preCloseCallback属性即可

       $scope.openConfirmDialog = function (callback, closeCallback ,msg) {
                    $scope.dialog = {
                        msg: msg
                    };
                    ngDialog.openConfirm({
                        template: 'app/app_common/views/ngdialog.confirm.html',
                        plain: false,
                        showClose: true,
                        closeByDocument: true,
                        closeByEscape: true,
                        scope: $scope,
                        width: '20%',
                        controller: 'ngDialogCtrl',
                        preCloseCallback:closeCallback,
                    }).then(callback);
                }

                //修改导ERP类型
                $scope.oldImpErpType = $scope.nextparam.emscaapportionh.imp_erp_type;
                $scope.impErpTypeChange = function(){
                    var impErpTypeChangeFun = function () {
                         $scope.$emit("changeImpErpType");
                    };
                    var closeFun = function(){
                        $scope.nextparam.emscaapportionh.imp_erp_type = $scope.oldImpErpType;
                    }
                    $scope.openConfirmDialog(impErpTypeChangeFun, closeFun,'更改导ERP类型将会清空预提明细，是否继续？');
                }
