[英]Use $compile inside Angular link function AND access directive arguements
[英]How to use the moment library in angular in a directive that uses compile instead of link
我的數據庫中有一個名為Actions的模型,其中包含連接文檔的樹(父級到子級),它們以有角度的指令遞歸地編譯,以便嵌套在其父級中。
我有以下代碼:
angular.module('crmDashboardApp')
.directive('actionDirective', function ($http, $compile, RecursionHelper) {
return {
scope: {
actionId: '=', // html:action-node, js:actionNode
actionList: '='
},
templateUrl: 'app/main/directive/action/action.directive.html',
replace: true,
restrict: 'E',
compile: function (element) {
return RecursionHelper.compile(element, function(scope, iElement, iAttrs, controller, transcludeFn){
scope.deleteAction = function (_action) {
var id = _action._id;
$http.delete('/api/actions', {
data: {'id':id},
headers: {"Content-Type": "application/json;charset=utf-8"} // we need to do this if we want to send params, otherwise we need to do traditional REST in URL
});
};
// Find for already called action list
scope.findAction = function (_id, _list) {
scope.actionNode = _.findWhere(_list, {_id:_id})
};
scope.findAction(scope.actionId, scope.actionList);
function calculateTimeSince(){
scope.fromNow = moment(scope.actionNode.content).fromNow(true);
}
setInterval(calculateTimeSince, 1000);
scope.fromNow = moment(scope.actionNode.content).fromNow(true);
});
}
};
});
這只會在加載時編譯一次,而在什么都不做之后更改范圍中的任何內容。 我希望setInterval函數更改變量scope.fromNow每秒更新一次並更新視圖(HTML使用簡單的{{fromNow}}對此進行引用)
我相信我將必須以某種方式重新編譯指令,但必須執行以下操作:
$compile(element.contents())(scope)
在setInterval函數中不起作用。
我的指令的HTML如下所示:
<div class="action-node">
<header>{{ actionNode.name }}</header>
<div class="row">
<h3 class="col-md-12">{{ actionNode.title }}</h2>
<h5 class="col-md-12">{{ actionNode.description }}</h5>
</div>
<div class="row">
<div class="col-md-3">Time Since: {{fromNow}}</div>
<div class="col-md-3">Content: {{ actionNode.content}}</div>
<div class="col-md-3">Duration Type:{{ actionNode.duration_type }}</div>
<div class="col-md-3">Type: {{ actionNode.type }}</div>
</div>
<div class="row">
<div class="col-md-4">
{{actionNode.children.length > 0 ? actionNode.children : "No children" }}
</div>
<form class="pull-right" ng-submit="deleteAction(actionNode)">
<input class="btn btn-primary" type="submit" value="Delete">
</form>
</div>
<div class="action-wrapper" ng-repeat="child in actionNode.children" ng-if="actionNode.children.length > 0">
<!-- <div class="row" ng-repeat="child in actionNode.children" ng-if="actionNode.children.length > 0" ng-style="{'margin-left': ({{actionNode.nest_level}}+1)*30+'px'}"> -->
<action-directive action-ID="child" action-list="actionList" />
</div>
</div>
您可以看到它再次在底部再次調用自身。 我也在使用RecursionHelper,所以無限循環不是問題。
除了使用setInterval
,您還需要使用Angular包裝器服務$interval
。
$interval
服務通過內部調用$ scope。$ apply來執行視圖循環來同步視圖和模型。
