另一个是Ajax中post的用法

实例

<!DOCTYPE html>
<html lang="en">
<head>
	<meta charset="UTF-8">
	<title>4.Ajax_POST</title>
</head>
<body>
	<form action="api/check.php" method="post">
		<fieldset>
			<legend>用户登录</legend>
			<p>
				<label for="email">邮箱:</label>
				<input type="email" name="email" id="email">
			</p>
			<p>
				<label for="password">邮箱:</label>
				<input type="password" name="password" id="password">
			</p>

			<p>
				<button>登录</button>
				<span id="tips" style="font-size:1.2em;font-weight: bolder;color:red"></span>
			</p>
			
			
		</fieldset>
	</form>
</body>
</html>
<script type="text/javascript" src="js/jquery.js"></script>
<script type="text/javascript">
	
	
	$('button:first').click (function(){
		//1.ajax-post提交的地址
		var url = 'api/user.php?m=login'

		//2.要提交到服务器的数据
		var data = {			
					"email": $('#email').val(),
					"password": $('#password').val()		
				}

		//3.设置执行成功的回调函数
		var success = function(res){
				if (res == '1') {
					$('#tips').text('登录成功,正在跳转中...')
					setTimeout(function(){
						location.href = 'api/index.php'
					},2000)
				} else {
					$('#tips').text('邮箱或密码错误,请重新输入...')
					$('#email').focus()
					setTimeout("$('#tips').empty()",2000)	
				}
			}

		//4.设置返回的数据格式为:json
		var dataType = 'json'

		//5.调用全局函数$.post()执行post请求
		$.post(url, data, success, dataType)

		
		
		//禁用默认提交
		return false
	})

			
</script>
