加载JavaScript的只在一个网页

Question

我想一个JavaScript仅在我的论坛的一个网页的工作，所以我用这个代码：

if (window.location.href.indexOf('/u1') != -1) { 

但它也影响到像/ U11网页，/ U12，/ U13 ，/ u14等。

我能做些什么才能使代码只在/ u1中工作？

Answer 1

试试这个，我忽略了你使用干净的URL的事实。

//split url into an array separated by the/
    var url = window.location.href.split("/"); 

    //store the page that you want the script to execute on 
    var rightPage = "u1"; 



//if the last index of the url array equals the value of the rightPage 
//note: -1 is subtracted because array indexes start at 0 
if (url[url.length - 1] === rightPage) {//begin if then else 


//do something if the your on the rightPage 
alert("right"); 

} 
else{ 

//do something if you are not on rightPage 
alert(page.join("/")); 

}//end if then else

这一个发现，如果有一个确切的段“U1”的URL里面，但在href路径不关心它的位置（这也会为http://somewhere.com/one/two/three/u1/foo/bar返回true），但它很简单应该够了。

var segments = window.location.href.split("/"); 
var found = false; 
// You can also do this loop with index and count the position if needed 
for (var segment in segments){ 
    if (segment == "u1"){ 
     found = true; 
     break; 
    } 
} 
// do with found whatever you need below
