我有一个带有ASP.NET应用程序的iframe,它包含UpdatePanel.我开始在应用程序中使用Angular,但是因为.NET回发而无法正常工作.
要解决这个问题,我使用了这个解决方案
with (Sys.WebForms.PageRequestManager.getInstance()) {
add_endRequest(onEndRequest); // regester to the end Request
}
function onEndRequest(sender, args) {
angular.bootstrap($('#mainDiv'), ['defaultApp']);
var rootscope = angular.element('#mainDiv').scope();
if (rootscope) {
rootscope.$apply();
}
}

而且效果很好.
问题是当我在ASP.NET页面中使用另一个ng-controller动态加载不同的用户控件时,Angular会抛出一个错误,说明该应用已经加载:
App Already Bootstrapped with this Element

所以问题是:我如何检查应用程序是否已经自举?我可以重装这个模块吗?我可以从元素中删除它而不是再次引导它吗?
谢谢.

我ng-include src在HTML中的多个地方使用指令.每个ng-include都为自己创造了一个孤立的范围,这显然给我带来了很多麻烦.
例如.
<div ng-controller="parent">
<div ng-include src="'id1'">
</div>
<div ng-include src="'id2'">
</div>
<div ng-include src="'id2'">
</div>
</div>

在上面提到的html中,创建了4个范围.在父级中controller定义了1,默认情况下每个都创建了3个ng-include src.
是否可以防止ng-include为自己创建一个孤立的范围?如果不可能那么有一个解决方法吗?
