ajax data nbsp quot val

后台转义字符问题
我用php输出ajax到html页面
其中ajax中的data属性如下
data:\'val=\'+\'\"\'+data+\'\"\',    相当于(data: val=" data ")
但是data本来就是一个字符串吧,不知道为什么要加双引号

到我到后台处理的时候$_POST['val'];发现前后多了转义字符"   无论我用什么方法都不能替换掉,解释掉"  请问怎么破
,如果可以,我最希望是改ajax中的参数写的方式,不知道是不是我写得太复杂
------解决方案--------------------
data: {val : data}

接收页
echo $_POST['val'];
