jquery 会有document.ready ,这是会把model value 给 set 去 jquery ，如果set 不进，可能需要整个渲染（refresh）。在操作时需要找到接口，在找到value。

 

所以jquery api 必须找到

1. document ready point

2. set view value

3. get view value

4. refresh 

5. on change

6. destroy

 

例子

//没有1 document ready 接口 & 4 refresh 接口 .directive('dtPicker', function () {        return {            require: '?ngModel',            restrict: 'A',            scope: {                viewMode: '@',                format: '@'            },            link: function (scope, element, attrs, ngModel) {                if (element[0]) {                    element.datetimepicker({                        format: scope.format,                    }).on('dp.change', function (e) { //4 on change                        var $picker = $(element).data("DateTimePicker");                        var date = $picker.date().toDate(); //3 get view value                        ngModel.$setViewValue(date);                    });                }                var originRender = ngModel.$render;                ngModel.$render = function () {                    originRender();                    var $picker = element.data("DateTimePicker");                    $picker.date(new Date(ngModel.$viewValue)); //2 set view value                }                scope.$on("$destroy", function () {                    var $picker = $element.data("DateTimePicker");                    $picker.destroy(); //6 destroy                });            }        }    })
