echo json_encode回到json对象，在前端获取到的却是字符串，而非json对象
echo json_encode返回json对象，在前端获取到的却是字符串，而非json对象
前端使用一下代码提交并处理后续结果
<br />
function del(id){<br />
if(confirm('确认要删除此关键字吗？')){<br />
$.post('./keyword',{ op:'del',id:id },function(result){<br />
alert(result); //正常这个部分应该显示的是object:object,但现在显示的是一个字符串<br />
if( result.code != 0 ){<br />
alert("删除失败！");<br />
}else{<br />
location.reload();<br />
}<br />
});<br />
}<br />
}<br />
<br />
服务端使用以下代码返回
<br />
echo json_encode(array("code"=>0));<br />
exit;<br />
正常情况下在前端alert result这个变量，应该显示的是object:object，可现在显示的却是这个json字符串。
