您可以使用$compile 服务 (docs) 将任意 HTML 编译成角度视图。
app.run(function($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,我已将视图附加到 $rootElement(这是引导模块时使用的元素,通常由 ng-app 指令);在许多情况下,您将在指令的链接函数中执行此类操作,并且可以访问相关元素。当然,您可以使用 jQuery 或 jqLite 获取原始 HTML,但请记住在链接范围内至少允许一个摘要循环(否则 HTML 尚未使用范围中的值更新) .

在ng-include 指令的内部,Angular's doing this very thing:
$compile(currentElement.contents())(currentScope);
[更新]
这是一个更完整的示例,展示了更接近您更新的问题的内容:
app.controller("MainController", function($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 sn-ps 使用t.elements 和t.things 毫无价值,因为t 是由外部 HTML 中的ng-repeat 创建的范围值。如果你愿意,你可以做一些范围体操,让它变得更好。
