不刷新页面修改地址栏及历史记录

//获取替换url参数后的url数据
function GetReplaceUrl(paramName, replaceWith) {
    var oUrl = this.location.href.toString();
    var re = eval('/(' + paramName + '=)([^&]*)/gi');
    var nUrl = oUrl.replace(re, paramName + '=' + replaceWith);
    return nUrl;
};
//替换url不刷新
function ReplaceUrl(paramName, replaceWith) {
    window.history.replaceState(null, null, GetReplaceUrl(paramName, replaceWith));
};

ReplaceUrl("id", 3);
将url中id替换为3
如果没有自动添加，有的话自动替换，完善代码如下

//获取替换url参数后的url数据
function GetReplaceUrl(paramName, replaceWith) {
    var oUrl = this.location.href.toString();
    var re = eval('/(' + paramName + '=)([^&]*)/gi');
    if (oUrl.search(re) > 0)
        var nUrl = oUrl.replace(re, paramName + '=' + replaceWith);
    else {
        if(oUrl.indexOf('?')>0)
            nUrl = oUrl + "&" + paramName + "=" + replaceWith;
        else
            nUrl = oUrl + "?" + paramName + "=" + replaceWith;
    }
    return nUrl;
};
