修改url中参数值

1.一种方法function changeUrlArg(url, arg, val){    var pattern = arg+‘=([^&]*)‘;    var replaceText = arg+‘=‘+val;    return url.match(pattern) ? url.replace(eval(‘/(‘+ arg+‘=)([^&]*)/gi‘), replaceText) : (url.match(‘[\?]‘) ? url+‘&‘+replaceText : url+‘?‘+replaceText);}2.麻烦的方法 

function replaceUrlParams(myUrl, newParams) {    var _url = $.urlGet(myUrl);    for (var x in newParams) {        var hasInMyUrlParams = false;        for (var y in _url) {            if (x.toLowerCase() == y.toLowerCase()) {                _url[y] = newParams[x];                hasInMyUrlParams = true;                break;            }        }        if (!hasInMyUrlParams) {            _url[x] = newParams[x];        }    }    var _result = "";    for (var p in _url) {        _result += (p + "=" + _url[p] + "&");    }    if (_result.substr(_result.length - 1) == "&") {        _result = _result.substr(0, _result.length - 1);    }    return  _result;}

(function($){

    $.extend({        urlGet:function(url)        {            var getUrl = url ? url.split("?") : window.location.href.split("?");            var _exportUrl = [];            if(getUrl.length > 1)            {                var params = getUrl[1].split("&");                for(var i=0, paramsLength = params.length; i<paramsLength; i++)                {                    var param = params[i].split("=");                    _exportUrl[param[0]] = param[1];                }            }            return _exportUrl;        }    });})(jQuery);

2种方法 都实现了功能 需求是修改一个值 就跳转 2钟方法 实现效果 不知道怎么样 有机会再测试
