extjs+php ,大家来看看是我的json输出的问题,还是我的extjs没有写对呢?
客户端:主要是看我鞋底subm这个函数有没得问题,

var main=new Ext.FormPanel({<br />
	title:'用户注册',<br />
	width:500,<br />
	frame:true,<br />
	bodyStyle:'margin:10px;',<br />
	renderTo:'tool',<br />
	height:400,<br />
	<br />
	items:[<br />
		{<br />
			layout:'column',<br />
			border:false,  <br />
			items:[<br />
				{	columnWidth:.4,<br />
					xtype:'textfield',<br />
					fieldLabel:'姓名',<br />
					labelWidth:30,<br />
					regex:/^[0-9a-zA-Z\.]+$/,<br />
					regexText:'只能是字母',<br />
					regexTextWidth:300,<br />
					allowBlank:false,<br />
					name:'name'<br />
					<br />
				},{<br />
					columnWidth:0.6,<br />
					layout:'column',<br />
					bodyStyle:'margin-left:20px',<br />
					border:false,<br />
					items:[<br />
				<br />
				{<br />
					columnWidth:.2,<br />
					xtype:'checkbox',<br />
					name:'aihao',<br />
					boxLabel:'足球',<br />
				},<br />
					{<br />
					columnWidth:.2,<br />
					xtype:'checkbox',<br />
					name:'aihao',<br />
					boxLabel:'踢足球'<br />
				}<br />
					<br />
				]<br />
			}<br />
			]<br />
		<br />
		}<br />
	<br />
	],<br />
	buttons:[<br />
			{text:'保 存',<br />
			 handler:subm},<br />
			 {text:'取 消'}<br />
		]<br />
	<br />
	<br />
	<br />
	<br />
	})<br />
<br />
function subm(){<br />
	 <br />
	  if (!main.isValid()) {  <br />
               return;  <br />
          }<br />
	    		main.getForm().submit({<br />
            	waitMsg:'数据提交中....',<br />
            	url:'./php.php',<br />
            	method:'POST',<br />
				params:main.getValues(),<br />
          	success:function(form,action){<br />
				alert("ok");<br />
            },<br />
                failure:function(form,action) {<br />
				alert('');<br />
            }<br />
        })<br />
<br />
	<br />
	<br />
	<br />
	}<br />
Copy after login


服务端:
<?php<br />
$str=$_POST["name"];<br />
$arr=array(<br />
"name"=>"xiobai",<br />
"sex"=>"28"<br />
);<br />
echo json_encode($arr);<br />
<br />
?>
Copy after login


问题他直接走failure:后面的函数,为什么不走success:
