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++

jQuery代码片段，以获取动态变量存储在url作为参数，并将它们存储为JavaScript变量，以供您的脚本使用:

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

example.com ? param1 = name&param2 = id = 6

$.urlParam('param1'); // name
$.urlParam('id');        // 6
$.urlParam('param2');   // null

带有空格的参数示例

http://www.jquery4u.com?city=Gold Coast
console.log($.urlParam('city'));  
//output: Gold%20Coast



console.log(decodeURIComponent($.urlParam('city'))); 
//output: Gold Coast

我总是把它写成一行。params有变量:

params={};location.search.replace(/[?&]+([^=&]+)=([^&]*)/gi,function(s,k,v){params[k]=v})

多行:

var params={};
window.location.search
  .replace(/[?&]+([^=&]+)=([^&]*)/gi, function(str,key,value) {
    params[key] = value;
  }
);

作为一个函数

function getSearchParams(k){
 var p={};
 location.search.replace(/[?&]+([^=&]+)=([^&]*)/gi,function(s,k,v){p[k]=v})
 return k?p[k]:p;
}

你可以这样用:

getSearchParams()  //returns {key1:val1, key2:val2}

or

getSearchParams("key1")  //returns val1

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>

我希望这能有所帮助。

 <script type="text/javascript">
   function getParameters() {
     var searchString = window.location.search.substring(1),
       params = searchString.split("&"),
       hash = {};

     if (searchString == "") return {};
     for (var i = 0; i < params.length; i++) {
       var val = params[i].split("=");
       hash[unescape(val[0])] = unescape(val[1]);
     }

     return hash;
   }

    $(window).load(function() {
      var param = getParameters();
      if (typeof param.sent !== "undefined") {
        // Do something.
      }
    });
</script>

最好的解决方案。

var getUrlParameter = function getUrlParameter(sParam) {
    var sPageURL = window.location.search.substring(1),
        sURLVariables = sPageURL.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]);
        }
    }
    return false;
};

这就是你如何使用这个函数假设URL是， http://dummy.com/?technology=jquery&blog=jquerybyexample。

var tech = getUrlParameter('technology');
var blog = getUrlParameter('blog');
