jquery 获取网页参数

新建个param.js文件，然后把下面的代码放进去。

$.request = (function () { 
    var apiMap = {}; 
    function request(queryStr) { 
        var api = {}; 
        if (apiMap[queryStr]) { return apiMap[queryStr]; } 
        api.queryString = (function () { 
            var urlParams = {}; 
            var e, 
            d = function (s) { return decodeURIComponent(s.replace(/\+/g, " ")); }, 
            q = queryStr.substring(queryStr.indexOf('?') + 1), 
            r = /([^&=]+)=?([^&]*)/g; 
            while (e = r.exec(q))     urlParams[d(e[1])] = d(e[2]);
            return urlParams; 
        })(); 
        api.getUrl = function () { 
            var url = queryStr.substring(0, queryStr.indexOf('?') + 1); 
            for (var p in api.queryString) { url += p + '=' + api.queryString[p] + "&";        } 
            if (url.lastIndexOf('&') == url.length - 1) { return url.substring(0, url.lastIndexOf('&')); } 
            return url; 
        } 
        apiMap[queryStr] = api; 
        return api; 
    } 
    $.extend(request, request(window.location.href)); 
    return request; 
})(); 

使用的时候：$.request.queryString["name"]就可以了，爽呆了吧~
