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

使用普通JavaScript，您可以很容易地获取参数(location.search)，获得子字符串(不带?)，并通过'&'分隔它，将其转换为数组。

当你遍历urlParams时，你可以再次用'='分割字符串，并将其添加到'params'对象中，作为object[elmement[0]] = element[1]。超级简单，易于访问。

http://www.website.com/?error=userError&type=handwritten

            var urlParams = location.search.substring(1).split('&'),
                params = {};

            urlParams.forEach(function(el){
                var tmpArr = el.split('=');
                params[tmpArr[0]] = tmpArr[1];
            });


            var error = params['error'];
            var type = params['type'];

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>

我希望使用完整的简单REG Exp

  function getQueryString1(param) {
    return decodeURIComponent(
        (location.search.match(RegExp("[?|&]"+param+'=(.+?)(&|$)'))||[,null])[1]
    );
  }

还有一个使用URI.js库的例子。

例子准确地回答了所问的问题。

var url = 'http://example.com?sent=yes'; var urlParams = new URI(url).search(true); // 1. Does sent exist? var sendExists = urlParams.sent !== undefined; // 2. Is it equal to "yes"? var sendIsEqualtToYes = urlParams.sent == 'yes'; // output results in readable form // not required for production if (sendExists) { console.log('Url has "sent" param, its value is "' + urlParams.sent + '"'); if (urlParams.sent == 'yes') { console.log('"Sent" param is equal to "yes"'); } else { console.log('"Sent" param is not equal to "yes"'); } } else { console.log('Url hasn\'t "sent" param'); } <script src="https://cdnjs.cloudflare.com/ajax/libs/URI.js/1.18.2/URI.min.js"></script>

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"];
