在javascript中使用$ _SERVER ['REQUEST_URI']的substr

Question

他们无论如何在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";
}

还有一个JSFiddle来展示这一点.
