获取window.location.href路径参数

function getUrlParams(params){
    var urlObj = {};
    if(!window.location.search){return false;}
    var urlParams = window.location.search.substring();
    var urlArr = urlParams.split('&');
    for(var i = ; i < urlArr.length; i++){
        var urlArrItem = urlArr[i].split('=');
        urlObj[urlArrItem[]] = urlArrItem[]
    }
　　// 判断是否有参数
    if(arguments.length>=){
        return urlObj[params]
    }
    return urlObj;
}
getUrlParams().ie;
getUrlParams('ie');

        GetQueryString(param) { //param为要获取的参数名 注:获取不到是为null
            var currentUrl = window.location.href; //获取当前链接
            var arr = currentUrl.split("?");//分割域名和参数界限
            if (arr.length > ) {
                arr = arr[].split("&");//分割参数
                for (var i = ; i < arr.length; i++) {
                    var tem = arr[i].split("="); //分割参数名和参数内容
                    if (tem[] == param) {
                        return tem[];
                    }
