在 Angular JS 中初始化 jQuery 插件 (RoyalSlider) [英] Initialising jQuery plugin (RoyalSlider) in Angular JS

问题描述

尝试加载 RoyalSlider 作为指令.这是我的指令，虽然我不确定为什么在第一次加载时有效，但在后续加载时无效:

app.directive('royalSlider', ['$timeout', function($timeout) {$(".royalSlider").royalSlider({键盘导航启用:真，箭头导航:真实，arrowsNavHideOnTouch: 真,imageScaleMode: '填充',幻灯片间距:0});}]);

错误:

TypeError: 无法读取未定义的属性编译"

假设问题是在所有内容完成后加载，我将其更改为:

app.directive('royalSlider', ['$timeout', function($timeout) {返回 {链接:函数($scope，元素，属性){$scope.$on('$viewContentLoaded', function () {$(".royalSlider").royalSlider({键盘导航启用:真，箭头导航:真实，arrowsNavHideOnTouch: 真,imageScaleMode: '填充',幻灯片间距:0});})}}}]);

然后什么也没发生.$timeout 也在那里，因为我也尝试过这个技巧，但无济于事.

解决方案

我已经有 2 种情况，指令和服务/工厂不能很好地发挥作用.

场景是我有(有)一个指令，该指令具有服务的依赖注入，并且从指令中我要求服务进行 ajax 调用(使用 $http).

最后，在这两种情况下，ng-repeat 根本没有归档，即使我给了数组一个初始值.

我什至尝试使用控制器和隔离范围来制定指令.只有当我将所有东西都移动到控制器时，它才能像魔术一样工作.其中之一是皇家滑块.

这是我的代码

app.service('AjaxService', ['$log', '$http', function ($log, $http) {var me = this;me.CallHttpAjaxAndMapSearch = function (url, targetObjext, propertyName, callback, splitObject) {$http.get(url).成功(功能(数据){//等，映射到selectedArray如果(属性名称){targetObjext[propertyName] = selectedArray;}别的 {targetObjext['selectedArray'] = selectedArray;}如果(回调){打回来();}});};}]);app.service('slidersService', ['$log', '$http', 'AjaxService', function ($log, $http, AjaxService) {var me = this;me.initRoyalSlider = 函数(url，元素，arrayName，sliderOptions，splitObject){我[数组名] = [];var successCallback = 函数滑块Service_successCallback() {setTimeout(函数滑块Service_successCallback_Timeout(){$log.log('setTimeout for ' + arrayName);element.royalSlider(sliderOptions);}, 0);};AjaxService.CallHttpAjaxAndMapSearch(url, me, arrayName, successCallback, splitObject);};}]);app.controller('royalSlider', function ($scope, $attrs, $log, slidersService) {var arrName = $attrs.royalSlider;var options = JSON.parse($attrs.royalSliderOptions);var element = $attrs.$$element;$scope.svc = 滑块服务；滑块服务.initRoyalSlider($attrs.royalSliderUrl, element, arrName, options, $attrs.splitObject);});

和 HTML

Trying to load the RoyalSlider as a Directive. Here's my directive, which works though I'm not sure exactly why, on first load but not on subsequent loads:

app.directive('royalSlider', ['$timeout', function($timeout) {

    $(".royalSlider").royalSlider({
        keyboardNavEnabled: true,
        arrowsNav: true,
        arrowsNavHideOnTouch: true,
        imageScaleMode: 'fill',
        slidesSpacing: 0
    });

}]);

with the error:

TypeError: Cannot read property 'compile' of undefined

Assuming the issue is loading when all content is finished, I changed it to this:

app.directive('royalSlider', ['$timeout', function($timeout) {
    return {
        link: function ($scope, element, attrs) {
            $scope.$on('$viewContentLoaded', function () {

                $(".royalSlider").royalSlider({
                    keyboardNavEnabled: true,
                    arrowsNav: true,
                    arrowsNavHideOnTouch: true,
                    imageScaleMode: 'fill',
                    slidesSpacing: 0
                });

            })
        }
    }
}]);

And Nothing happens. $timeout is also in there because I've tried that trick too, to no avail.

解决方案

I already have 2 situations where directives and services/factories didn't play well.

The scenario is that I have (had) a directive that has dependency injection of a service, and from the directive I ask the service to make an ajax call (with $http).

In the end, in both cases the ng-repeat did not file at all, even when I gave the array an initial value.

I even tried to make a directive with a controller and an isolated-scope. Only when I have moved everything to a controller then it worked like magic. One of them was the royal slider.

Here is my code

app.service('AjaxService', ['$log', '$http', function ($log, $http) {
    var me = this;
    me.CallHttpAjaxAndMapSearch = function (url, targetObjext, propertyName, callback, splitObject) {
        $http.get(url)
               .success(function(data){
                //etc., mapping to selectedArray
                if (propertyName) {
                    targetObjext[propertyName] = selectedArray;
                }
                else {
                    targetObjext['selectedArray'] = selectedArray;
                }
                if (callback) {
                    callback();
                }
            });
    };
}]);

app.service('slidersService', ['$log', '$http', 'AjaxService', function ($log, $http, AjaxService) {
    var me = this;
    me.initRoyalSlider = function (url, element, arrayName, sliderOptions, splitObject) {
        me[arrayName] = [];
        var successCallback = function slidersService_successCallback() {
            setTimeout(function slidersService_successCallback_Timeout() {
                $log.log('setTimeout for ' + arrayName);
                element.royalSlider(sliderOptions);
            }, 0);

        };
        AjaxService.CallHttpAjaxAndMapSearch(url, me, arrayName, successCallback, splitObject);
    };
}]);

app.controller('royalSlider', function ($scope, $attrs, $log, slidersService) {
    var arrName = $attrs.royalSlider;
    var options = JSON.parse($attrs.royalSliderOptions);
    var element = $attrs.$$element;

    $scope.svc = slidersService;
    slidersService.initRoyalSlider($attrs.royalSliderUrl, element, arrName, options, $attrs.splitObject);
});

And the HTML

            <div class="slides royalSlider rsMinW "
                    ng-controller="royalSlider" 
                    royal-slider="mainSlider" 
                    royal-slider-options='{"loop":true,"autoPlay":{"enabled":true,"pauseOnHover":true,"delay":3000},"arrowsNav":false,"controlNavigation":"bullets"}'
                    royal-slider-url="/_api/search/query?bla bla">
                   <div ng-repeat="slide in svc.mainSlider">
