JS獲取Url傳遞過來的參數

  //獲取URl參數
    function getUrlParam(name) {
        var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)"); //構造一個含有目標參數的正則表達式對象
        var r = window.location.search.substr(1).match(reg);  //匹配目標參數
        if (r != null) return unescape(r[2]); return null; //返回參數值
    }

使用方法

 var vAccount = getUrlParam("userAccount");

方法2

function getQueryStringByKey(key) {
    var returnValue = "";
    var str = window.location.search;
    if ($.trim(str).length == 0) {
        returnValue = "";
    }
    else {
        str = str.substr(1);
        var strArr = str.split("&");
        for (var i = 0; i < strArr.length; i++) {
            var index = strArr[i].indexOf("=");
            var keyStr = strArr[i].substring(0, index);
            if (key == keyStr) {
                returnValue = strArr[i].substr(index + 1);
                break;
            }
        }
    }
    return returnValue;
}
