js 设置url参数转

// 获取地址栏的参数数组
function getUrlParams() {
    var search = window.location.search;
    // 写入数据字典
    var tmparray = search.substr(1, search.length).split("&");
    var paramsArray = new Array;
    if (tmparray != null) {
        for (var i = 0; i < tmparray.length; i++) {
            var reg = /[=|^==]/;    // 用=进行拆分，但不包括==
            var set1 = tmparray[i].replace(reg, '&');
            var tmpStr2 = set1.split('&');
            var array = new Array;
            array[tmpStr2[0]] = tmpStr2[1];
            paramsArray.push(array);
        }
    }
    // 将参数数组进行返回
    return paramsArray;
}

// 根据参数名称获取参数值
function getParamValue(name) {
    var paramsArray = getUrlParams();
    if (paramsArray != null) {
        for (var i = 0; i < paramsArray.length; i++) {
            for (var j in paramsArray[i]) {
                if (j == name) {
                    return paramsArray[i][j];
                }
            }
        }
    }
    return null;
