<!--
angular.module('notesApp',[])
.controller('MainCtrl',[function(){
var self=this;
self.submit=function(){
console.log("User name="+self.user.name+
" age="+self.user.age+
" mail="+self.user.mail+
" date="+self.user.date+
" sn="+self.user.sn+
" url="+self.user.url);
alert("Form submitted.");
};
}]);
//-->
</script>
效果：
要点：
目前我感觉AngularJS对复杂表单的验证不是那么方便，对浏览器的依耐性也强。常规验证的JS代码其实不复杂，AngularJS的优势在此并不明显。
