我有以下穿梭盒指令:
<shuttle-boxes ng-options="item for item in itemList" ng-model="myModel" />
我的模板如下所示:
template: '<div class="shuttle-boxes">' +
'<select multiple="multiple" class="shuttle-boxes-left"></select>' +
'<button class="shuttle-boxes-btn" type="button"><i class="icon icon-arrow-right"></i></button>' +
'<button class="shuttle-boxes-btn" type="button"><i class="icon icon-arrow-left"></i></button>' +
'<select multiple="multiple" class="shuttle-boxes-right"></select>' +
'</div>'
我想要做的是从<shuttle-boxes>
获取ng-options转发器并使用它来填充<select class="shuttle-boxes-left">
。
我尝试这样做的方法是无效的只是将ng-options属性复制到选择列表中,如下所示:
var availableList = cElement.find('.shuttle-boxes-left'),
repeater = cAttrs.ngOptions;
availableList.attr('ng-options', repeater);

我做错了什么?

我建议您只将itemList传递给指令(和myModel),并将ng-options放在模板中:
<shuttle-boxes items="itemList" ng-model="myModel"></shuttle-boxes>
指令:
myApp.directive('shuttleBoxes', function($timeout) {
return {
restrict: 'E',
scope: { items: '=', ngModel: '='},
template: '<div class="shuttle-boxes">' +
'<select multiple="multiple" class="shuttle-boxes-left"
ng-options="item for item in items" ng-model="ngModel"></select>' +
'<button class="shuttle-boxes-btn" type="button">' +
'<i class="icon icon-arrow-right"></i></button>' +
'<button class="shuttle-boxes-btn" type="button">' +
'<i class="icon icon-arrow-left"></i></button>' +
'<select multiple="multiple" class="shuttle-boxes-right"></select>' +
'</div>',
replace: true
}
});
