这可能有点过分了，但是现在有一个非常流行的用于解析uri的库，叫做URI.js。

例子

var uri = "http://example.org/foo.html?technology=jquery&technology=css&blog=stackoverflow"; var components = URI.parse(uri); var query = URI.parseQuery(components['query']); document.getElementById("result").innerHTML = "URI = " + uri; document.getElementById("result").innerHTML += "<br>technology = " + query['technology']; // If you look in your console, you will see that this library generates a JS array for multi-valued queries! console.log(query['technology']); console.log(query['blog']); <script src="https://cdnjs.cloudflare.com/ajax/libs/URI.js/1.17.0/URI.min.js"></script> <span id="result"></span>

如果有&在URL参数像filename="p&g.html"&uid=66

在这种情况下，第一个函数将不能正常工作。所以我修改了代码

function getUrlParameter(sParam) {
    var sURLVariables = window.location.search.substring(1).split('&'), sParameterName, i;

    for (i = 0; i < sURLVariables.length; i++) {
        sParameterName = sURLVariables[i].split('=');

        if (sParameterName[0] === sParam) {
            return sParameterName[1] === undefined ? true : decodeURIComponent(sParameterName[1]);
        }
    }
}

使用URLSearchParams:

var params = new window.URLSearchParams(window.location.search);
console.log(params.get('name'));

注意兼容性(大多数情况下是好的，但IE和Edge，可能是不同的故事，检查这个兼容性参考:https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams)

$.urlParam = function(name) {
  var results = new RegExp('[\?&]' + name + '=([^&#]*)').exec(window.location.href);
  return results[1] || 0;
}

Sameer回答的咖啡脚本版本

getUrlParameter = (sParam) ->
  sPageURL = window.location.search.substring(1)
  sURLVariables = sPageURL.split('&')
  i = 0
  while i < sURLVariables.length
    sParameterName = sURLVariables[i].split('=')
    if sParameterName[0] == sParam
      return sParameterName[1]
    i++

我用了这个，很管用。 http://codesheet.org/codesheet/NF246Tzs

function getUrlVars() {
    var vars = {};
    var parts = window.location.href.replace(/[?&]+([^=&]+)=([^&]*)/gi, function(m,key,value) {
    vars[key] = value;
    });
return vars;
}


var first = getUrlVars()["id"];
