本文深入探讨了AngularJS中遇到的常见错误AppAlreadyBootstrapped及其产生的原因，特别是当在同一页面上多次加载AngularJS库导致的应用初始化冲突。文章详细解释了如何通过合理使用`ng-app`和`angular.bootstrap`来避免此类问题，同时提供了实例演示错误的出现方式及解决策略。

Error: ng:btstrpd
App Already Bootstrapped with this Element
App Already Bootstrapped with this Element '{0}'
Description
Occurs when calling angular.bootstrap on an element that has already been bootstrapped.
This usually happens when you accidentally use both ng-app and angular.bootstrap to bootstrap an application.
<html> ... <body ng-app = "myApp" > <script> angular . bootstrap ( document . body , [ 'myApp' ]); </script> </body> </html>Note that for bootstrapping purposes, the <html> element is the same as document, so the following will also throw an error.
<html> ... <script> angular . bootstrap ( document , [ 'myApp' ]); </script> </html>You can also get this error if you accidentally load AngularJS itself more than once.
<html ng-app > <head> <script src = "angular.js" ></script> ... </head> <body> ... <script src = "angular.js" ></script> </body> </html>

根据 这个话。
根据 这个话。
angular.element(document).ready 这句话在IE下 会执行两次~ 所以才会报 error SCRIPT5022 ng:btstrpd 错。
