问题:
form表单提交,响应类型text/plain,不走sucess,直接结束
但是页面显示内容如下
![这里写图片描述](http://img.blog.csdn.net/20170928170328772?water/2/text/aHR0cDovL2Jsb2cuY3Nkbi5uZXQvemhvdTkyMDc4NjMxMg==/font/5a6L5L2T/fontsize/400/fill/I0JBQkFCMA==/dissolve/70/gravity/SouthEast)即使后面我返回text/html,json也没有用。
...
success:function(){
},
error:function(){
//这个error回调你加上,看看程序是不是走到这里了
}
});
//如果进了error,观察一下这3个变量
}
var s=result;
var result = eval('(' + result + ')');
你定义了相同的变量名,把变量名改掉试试
