1.
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
<script type="text/javascript">
$(function(){
$.ajax({
url:'xxxx',
type:'post',
dataType:'json',
data:{
'p1':$('#p1'),
'p2':$('#p2')
},
success:function(result){
//回调函数
}
});
});
</script>
</head>
<body>
<form id="myForm" action="">
<input id="p1" name="p1" value="p1"/>
<input id="p2" name="p2" value="p2"/>
<input id="btn" type="button" value="提交"/>
</form>
</body>
</html>
2.$('#id').serialize( ); 这时表单的按钮的type不可以是submit，否则自提交数据，也就是自动刷新;改为button
<!DOCTYPE html>

<script type="text/javascript">
$(function(){
$.ajax({
url:'xxxx',
type:'post',
dataType:'json',
data:$("#myForm").serialize(),
success:function(result){
//回调函数
}
});
});
</script>

<body>
<form id="myForm" action="">
<input id="p1" name="p1" value="p1"/>
<input id="p2" name="p2" value="p2"/>
<input id="btn" type="button" value="提交"/>
</form>
</body>
</html>
3.使用jQuery Form插件提供的ajaxSubmit()函数
$('#myform').ajaxSubmit({
type: 'GET/POST',
url: 'xx.php',
dataType: 'json',
success: fn,
clearForm: true,
resetForm: true
});
