我正在处理由5个指令组成的页面,例如:
<directive-one></directive-one>
<directive-two></directive-two>
<directive-three></directive-three>
<directive-four></directive-four>
<directive-five></directive-five>
我希望能够按需重新排序这些内容,以便用户可以控制其页面的外观。我能想到的唯一方法是将它们放入ng-repeat中:
$scope.directiveOrder = [{
name: "directive-one",
html: $sce.trustAsHtml('<directive-one></directive-one>'),
order: 1
}, ...
HTML:
<div ng-repeat="directive in directiveOrder" ng-bind-html="directive.html">
{{directive.html}}
</div>
这将为我提供正确的标签,但它们不会被角度处理为指令。有办法吗?我假设它与$sce
没有处理它有关,但我可能会离开?

尝试创建一个新指令并使用$ compile来呈现每个指令:

element.append($compile(template)(scope));
}
}
})
.controller('MyCtrl', function($scope, $compile) {
$scope.directives = [{
name: 'directive-one'
}, {
name: 'directive-two'
}];
$scope.reOrder = function () {
$scope.directives.push($scope.directives.shift());
console.log($scope.directives);
};
});

我希望你能轻松完成它。
var myApp = angular.module('myApp',[])
.directive('directiveOne', function() {
return {
restrict: 'E',
scope: {},
template: '<h1>{{obj.title}}</h1>',
controller: function ($scope) {
$scope.obj = {title: 'Directive One'};
}
}
})
.directive('directiveTwo', function() {
return {
restrict: 'E',
scope: {},
template: '<h1>{{obj.title}}</h1>',
controller: function ($scope) {
$scope.obj = {title: 'Directive Two'};
}
}
});
myApp.controller('ctrl',function($scope){
$scope.data = [{name:'directive-one'},{name:'directive-two'}];
});
<html ng-app='myApp'>
<head>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.17/angular.min.js"></script>
</head>
<body ng-controller='ctrl'>
<div ng-repeat='item in data'>
