我所知道的是当我想将HTML插入到视图中时,我使用’ng-bind-html’或’ng-bind-html-unsafe’。
我不知道的是如何插入HTML并使Angular解析其内容
即如果有’ng-repeat’,我想要Angular来解析呢?
更新1:
例:
HTML:
<div ng-repeat="t in ts" ng-bind-html-unsafe="t.html()"></div>
JS:
function Controller($scope) { $scope.ts = {obj1: new obj(),obj2: new obj(),ob3: new obj()}; } function obj() { // which may be "<div ng-repeat="s in somthing">{{s}}</div>" // or "<ul><li ng-repeat="s in somthing">{{s.k}}</li></ul>" // or something else var _html; this.html = function() { return _html; } }
我尝试使用上述方法,但Angular只是打印{{s}}或{{s.k}}。
您可以使用$ compile服务(
docs)将任意HTML编译成角度视图。
原文链接:https://www.f2er.com/angularjs/144659.htmlapp.run(function($rootScope,$compile,$rootElement) { // We'll create a new scope to use as the context for the view. $scope = $rootScope.$new(); $scope.model = [{name: 'first'},{name: 'second'},{name: 'third'}]; // Calling `$compile(html)` returns a function that,when called with // a context object,links the compiled HTML to the given context (e.g. // binds scope-based expressions in the view to the passed in scope). var html = "<div ng-repeat='m in model'>{{m.name}}</div>"; var linkingFunction = $compile(html); var elem = linkingFunction($scope); // You can then use the DOM element like normal. $rootElement.append(elem); });
在这种情况下,我将视图附加到$ rootElement(这是引导模块时使用的元素,通常是由ng-app指令);在许多情况下,您将在指令的链接功能中执行此类操作,并可访问该元素。当然,您可以使用jQuery或jqLite获取原始HTML,但请记住在链接的范围之前至少允许一个摘要循环(否则HTML将不会被范围内的值更新) 。

在ng-include指令的下方,Angular’s doing this very thing:
$compile(currentElement.contents())(currentScope);
[更新]
这是一个更完整的例子,它演示了一些更接近你更新的问题:
app.controller("MainController",function($scope) { $scope.ts = [ { elements: ['one','two','three'],html: '<div ng-repeat="elem in t.elements">{{elem}}</div>' },{ things: [8,9,10],add: function(target) { var last = target[target.length - 1]; target.push(last + 1); },html: '<ul><li ng-repeat="num in t.things">{{num}}</li>' + '<li><button ng-click="t.add(t.things)">More</button></li></ul>' } ]; }); app.directive("bindCompiledHtml",function($compile,$timeout) { return { template: '<div></div>',scope: { rawHtml: '=bindCompiledHtml' },link: function(scope,elem,attrs) { scope.$watch('rawHtml',function(value) { if (!value) return; // we want to use the scope OUTSIDE of this directive // (which itself is an isolate scope). var newElem = $compile(value)(scope.$parent); elem.contents().remove(); elem.append(newElem); }); } }; });
<div ng-controller="MainController"> <div ng-repeat="t in ts" bind-compiled-html="t.html"></div> </div>

HTML片段使用t.elements和t.things是不值得的,因为t是由外部HTML中的ng-repeat创建的范围值。你可以做一些范围体操,使它更好一点,如果你喜欢。
