angular学习的一些小笔记，中之ng-init
ng-init是给angular执行给定的表达式，初始化变量的值
<!DOCTYPE html>
<html>
<head>
<meta charset='UTF-8'>
<title>ng-init</title>
<script type="text/javascript" src='static/plugins/angular.min.js'></script>
</head>
<body>
<div ng-app='' ng-init='myTest="hello world"'>
{{myTest}}
</div>
</body>
</html>这样就初始化了myTest的值，ng-app没有设值，要是设置的话，就要js啦，要不然就得报错了
