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 />

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:
