javascript - 如何将范围值传递给指令 Controller

Question

我正在尝试将范围值数组从 Controller 传递到指令，这如何可能。

我需要将此值传递给我的指令 Controller $scope.recipientsOrgIdArr.push(data.latedEntityInstanceId);

HTML 文件

<search  searchobj="tei_org"  selecteditemslist="recipientsOrgIdArr"   searchid="organisation" />

搜索指令

.directive('search', function ($timeout) {
    return {
        restrict: 'AEC',
        scope: {
            selecteditemslist: "="
}
link: function (scope, elem, attrs) {
console.log(scope.selecteditemslist);  // getting as undefined

//how can i get scope value here
}
}
})

请帮我解决这个问题，提前致谢

您遇到的问题是，在调用指令链接函数时，selecteditemslist 尚未设置。

试试这个

.directive('search', function ($timeout) {
    return {
        restrict: 'AEC',
        scope: {
            selecteditemslist: "="
        }
        link: function (scope, elem, attrs) {
            scope.$watch('selecteditemslist', function(value) {
                if(value){
                    console.log(scope.selecteditemslist);
                }
        }...
