Prevent the login page from appearing in the frame js code_javascript skills

When using frame page for nested development, when the server is restarted, the login page will appear in the frame page,

So you need to use js to determine the current address information on the login page, and then jump to a separate login page.

js code is as follows:

$("document").ready(function(){ 
//防止在frame里面出现登录页面 
if(top.location!==self.location){ 
//alert(top.location); 
//alert(self.location); 
top.location.href=self.location.href; 
} 
});
