javascript - 从jQuery中的字符串中提取某个查询的值

Question

var test = "http://www.example.org/search?q=whatever&another=moretext";

如何在上面的查询字符串中提取another's value ( moretext) 并从中创建一个变量？

Answer 1

var test = "http://www.example.org/search?q=whatever&another=moretext";
var another = test.split('another=');

another 是一个数组，其中 another[0] = 'http://www.example.org/search?q=whatever&' 和 another[1] = 'moretext'。

将此功能放在您的包中：

 function querySt(qsName, url)
        {
            var theUrl;
            if (url == null || url == undefined)
                theUrl = window.location.search.substring(1); else theUrl = url;
            var g = theUrl.split("&");
            for (var i = 0; i < g.length; i++) {
                var pair = g[i].split("=");
                if (pair[0].toLowerCase() == qsName.toLowerCase())
                {
                    return pair[1];
                }
            }
            return null;
        }

alert(querySt("another")+'      '+querySt("q"));
