使用ng-repeat渲染条件标记
Given this data in my controller :
在我的控制器中给出这些数据:
$scope.data = [
{id: "1", ElementType: "paragraph", text: "some content"},
{id: "2", ElementType: "listItem", text: "some list item content"},
{id: "3", ElementType: "quote", text: "some quote"}
]
An given this ng-repeat in my view:
在我看来,给出了这个ng-repeat:
<div ng-repeat="item in data">{{item.text}}</div>
How can I render this HTML ? :
如何呈现此HTML? :
<p>Some content</p>
<ul>
<li>some list item content</li>
</ul>
<blockquote>some quote</blockquote>
I've explored ng-switch but it keeps the parent div. In other words I want to replace the HTML produced by ng-repeat with new markup based on an object attribute.
我已经探索过ng-switch,但它保留了父div。换句话说,我想用基于对象属性的新标记替换ng-repeat生成的HTML。

You can do it inside a directive using the $compile
angular function like shown in this plnkr.
您可以使用$ plangle中的$ compile angular函数在指令内执行此操作。
UPDATE Here is a plnkr that works better
更新这是一个更好的plnkr
Here is the key part:
这是关键部分:
link: function (scope, ele, attrs) {
scope.$watch(attrs.dynamic, function(html) {
var htmlStr = '';
var repeat = attrs.repeat;
for(var i = 0; i< repeat; i++){
htmlStr += html;
}
ele.html(htmlStr);
$compile(ele.contents())(scope);
});
}
Your controller would look like this:
你的控制器看起来像这样:
function MyController($scope) {
$scope.html = '<p>{{id}}</p>\
<ul>\
<li>{{ElementType}}</li>\
</ul>\
<blockquote>{{text}}</blockquote>';
}
From your example, you'd remove the ng-repeat entirely and just use this directive. One change is that you'd pass in the whole $scope.data and dynamically pull out the bits you wanted to use in your html string. But because it's a string, that should be easy to do with simple string concatenation.
从您的示例中,您将完全删除ng-repeat并使用此指令。一个变化是你传入整个$ scope.data并动态地拉出你想在html字符串中使用的位。但是因为它是一个字符串,所以使用简单的字符串连接应该很容易。
One final thing - you are probably going to have to put some tags in so you can replace your static content with dynamic data from your array. Kind of like ng-repeat! (but different all the same).
最后一件事 - 你可能不得不放入一些标签,这样你就可以用你阵列中的动态数据替换你的静态内容。有点像ng-repeat! (但不同的都是一样的)。
Finally, you could use interpolate
to fill up your html string:
最后,您可以使用interpolate来填充您的html字符串:
$interpolate(template)({
id: id,
ElementType: ElementType,
text: text
});
Where you would get the data for these items from the controller
您可以从控制器获取这些项目的数据
