Question

Jquery multiselect与ng-option完美匹配。请参阅下面的HTML，指令和控制器。

 <select multiselect multiple ng-model="sched.select"  style="width:130px;" 
 ng-options="option.name for option in availableOptions track by option.value" >


.directive('multiselect', function ($timeout) {
return {
    restrict: 'A',
    scope: {
        model: '='
    },
    transclude: true,
    require: 'ngModel',
    link: function (scope, element, attrs, controller, transclude) {
        $timeout(function() {
            transclude(function (clone) {
                element.append(clone);
                $(element).multiselect();
            });
        });
    }
}
});

 .controller('CreateSubject', function ($scope, factory, $cookieStore,     
 $location, $rootScope){
 $scope.availableOptions = [
 {value: "M", name: 'Monday'},
 {value: "T", name: 'Tuesday'},
 {value: "W", name: 'Wednesday'},
 {value: "Th", name: 'Thursday'},
 {value: "F", name: 'Friday'},
 {value: "S", name: 'Saturday'}    
];
});

现在我的问题是如何在这种情况下预选值？我已经尝试过这个解决方案JQuery multiselect - Set a value as selected in the multiselect dropdown，但它给了我一个错误。

您可以尝试在控制器中使用initilaze，并在option.name as option.name标记中使用select，而无需使用track by。

在您的控制器中：

.controller('CreateSubject', function ($scope){
 $scope.availableOptions = [
     {value: "M", name: 'Monday'},
     {value: "T", name: 'Tuesday'},
     {value: "W", name: 'Wednesday'},
     {value: "Th", name: 'Thursday'},
     {value: "F", name: 'Friday'},
     {value: "S", name: 'Saturday'}    
  ];
  $scope.sched = {};
  $scope.sched.select =[$scope.availableOptions[0].name,$scope.availableOptions[1].name]
;});

和HTML：

<select multiselect multiple ng-model="sched.select"  style="width:130px;" 
         ng-options="option.name as option.name for option in availableOptions" >

    </select>

NB。如果要将值设置为option.value as option.name作为选定值，则应使用M, T。

和文件加载顺序需要遵循 jquery，bootstrap（css，js），angular，bootstrap-multiselect（js，css），你的脚本文件

它可能对你有所帮助。
