本文介绍了一个基于AngularJS的简易在线笔记应用程序。该应用包括文本输入、字符计数、保存及清除功能。通过使用AngularJS框架简化了前端开发流程。

<!DOCTYPE html>
<html ng-app="myNoteApp">

	<head>
		<meta charset="utf-8" />
		<title></title>
		<script type="text/javascript" src="js/angular.min.js"></script>
	</head>

	<body>

		<div ng-controller="myNoteCtrl">
			<h2>我的笔记</h2>
			<p>
				<textarea ng-model="message" cols="40" rows="10">
				
			</textarea>
			</p>
			<p>
				<button ng-click="save()">保存</button>
				<button ng-click="clear()">清除</button>
			</p>
			<p>Number of character left:<span ng-bind="left()"></span></p>
		</div>
		<script type="text/javascript">
			var app = angular.module("myNoteApp", []);
			app.controller("myNoteCtrl", function($scope) {
				$scope.message = "";
				$scope.left = function() {
					return 100 - $scope.message.length;
				};
				$scope.clear = function() {
					$scope.message = "";
				};
				$scope.save = function() {
					alert("Note Saved");
				};
			});
		</script>
