substr with $ _SERVER ['REQUEST_URI'] in javascript

Question

他们无论如何都要在javascript中复制这样的PHP函数？

$uri = explode("/",substr($_SERVER['REQUEST_URI'],1)); 
if((isset($uri[0])) && ($uri[0]!="")) {$page = $uri[0];} else {$page = "home";} 

Answer 1

试试这个：

var uri = location.pathname.substr(1).split('/'); 
if(0 in uri && uri[0] != "") { 
    var page = uri[0]; 
} else { 
    var page = "home"; 
} 

而一个JSFiddle以行动证明这一点。
