从Hashtag Url获取参数

Question

我想从一个url看起来像这样的'#spagepage？id = 5'我用这个函数似乎没有工作有问题的函数是：

function getParam(name) { 
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); 
var regexS = "[\\?&]" + name + "=([^&#]*)"; 
var regex = new RegExp(regexS); 
var results = regex.exec(window.location.href); 
if (results == null) 
    return ""; 
else 
    return results[1]; 
} 

有没有一种方法可以修改或替换这个函数来从上面提到的url中提取id？

Answer 1

function getParameterByName(name) { 
name = name.replace(/[\[]/, "\\\[").replace(/[\]]/, "\\\]"); 
var regex = new RegExp("[\\?&]" + name + "=([^&#]*)"), 
    results = regex.exec(location.search); 
return results == null ? "" : decodeURIComponent(results[1].replace(/\+/g, " ")); 
}
