在jqery中有这样一个方法,$.post()下面就这个方法做一个简单的实例:
jQuery.post( url, [data], [callback], [type] ) :
使用POST方式来进行异步请求
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>Untitled Document</title>
<script type="text/javascript" src=\'#\'" /jquery-1.3.2.js"></script>
<script language="javascript">
function checkemail(){
if($('#email').val() == ""){
$('#msg').html("please enter the email!");
$('#email').focus;
return false;
}
if($('#address').val() == ""){
$('#msg').html("please enter the address!");
$('#address').focus;
return false;
}
ajax_post();
}
function ajax_post(){
$.post("action.php",{email:$('#email').val(),address:$('#address').val()},
function(data){
//$('#msg').html("please enter the email!");
//alert(data);
$('#msg').html(data);
},
"text");//这里返回的类型有:json,html,xml,text
}
</script>
</head>
<body>
<form id="ajaxform" name="ajaxform" method="post" action="action.php">
<p>
email<input type="text" name="email" id="email"/>
</p>
<p>
address<input type="text" name="address" id="address"/>
</p>
<p id="msg"></p>
<p>
<input name="Submit" type="button" value="submit" onclick="return checkemail()"/>
</p>
</form>
</body>
</html>
2.php页面(action.php)
$email = $_POST["email"];
$address = $_POST["address"];
//echo $email;
//echo $address;
echo "success";
?>
说明:当
点击按钮时,注意按钮现在的类型是button.在不使用$.post()方法时,按钮类型是submit,这样submit提交form里的数据,采用
post方法传递到页面action.php,这时在页面action.php中就能接受到传过来的数据。当采用$.post方法时,我们在函数
ajax_post()方法中其实就是使用了post的方法。(要引用jquery库文件)
