获取url参数jquery或如何在js中获取查询字符串值

本文翻译自：Get url parameter jquery Or How to Get Query String Values In js

I have seen lots of jQuery examples where parameter size and name are unknown. 我已经看到许多jQuery示例，其中参数大小和名称是未知的。 My url is only going to ever have 1 string: 我的网址只会有1个字符串：

http://example.com?sent=yes

I just want to detect: 我只想检测：

1. Does sent exist? sent是否存在？
2. Is it equal to "yes"? 等于“是”吗？

Try this working demo http://jsfiddle.net/xy7cX/ 试试这个工作演示 http://jsfiddle.net/xy7cX/

API: API：

• inArray : http://api.jquery.com/jQuery.inArray/ inArray ： http : inArray

This should help :) 这应该有帮助:)

code 码

I hope this will help. 我希望这将有所帮助。

 <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>

Best solution here . 最好的解决方案在这里 。

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]);
        }
    }
};

And this is how you can use this function assuming the URL is, 假设网址是，这就是使用该功能的方式，

jQuery code snippet to get the dynamic variables stored in the url as parameters and store them as JavaScript variables ready for use with your scripts: jQuery代码片段获取作为参数存储在url中的动态变量，并将其存储为可与脚本一起使用的JavaScript变量：

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

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

example params with spaces 带空格的示例参数

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



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

This will give you a nice object to work with 这将为您提供一个不错的对象

    function queryParameters () {
        var result = {};

        var params = window.location.search.split(/\?|\&/);

        params.forEach( function(it) {
            if (it) {
                var param = it.split("=");
                result[param[0]] = param[1];
            }
        });

        return result;
    }

And then; 接着;

    if (queryParameters().sent === 'yes') { .....
