base64记录查询参数！

Base64.encode('dankogai');  // ZGFua29nYWk=
Base64.encode('小飼弾');    // 5bCP6aO85by+
Base64.encodeURI('小飼弾'); // 5bCP6aO85by-

Base64.decode('ZGFua29nYWk=');  // dankogai
Base64.decode('5bCP6aO85by+');  // 小飼弾
// note .decodeURI() is unnecessary since it accepts both flavors
Base64.decode('5bCP6aO85by-');  // 小飼弾

首页，获取查询参数！

/**
* [获取URL中的参数名及参数值的集合]
* 示例URL:http://htmlJsTest/getrequest.html?uid=admin&rid=1&fid=2&name=小明
* @param {[string]} urlStr [当该参数不为空的时候，则解析该url中的参数集合]
* @return {[string]}       [参数集合]
*/
function GetRequest(urlStr) {
    if (typeof urlStr == "undefined") {
        var url = decodeURI(location.search); //获取url中"?"符后的字符串
    } else {
        var url = "?" + urlStr.split("?")[1];
    }
    var theRequest = new Object();
    if (url.indexOf("?") != -1) {
        var str = url.substr(1);
        strs = str.split("&");
        for (var i = 0; i < strs.length; i++) {
            theRequest[strs[i].split("=")[0]] = decodeURI(strs[i].split("=")[1]);
        }
    }
    return theRequest;
}

var request = Base64.encode(JSON.stringify(GetRequest()));
console.log(Base64.decode(request));
if (request) {
    var tail = '&request=' + request;
} else {
    var tail = '';
}

传入编辑页面

$(".edit").on('click', function () {
    var id = $(this).data('id');
    window.location.href = '__APP__/Product/edit?id=' + id + tail;
});

后台获取，并传入

$request = $_GET['request'];
$this->assign('request', $request);

<input type="hidden" name="request" id="request" value="{$request}" />

取消，或者完成编辑的时候，解析Base64

var request = $("#request").val();
if (request) {
    var str = '&request=' + request;
} else {
    var str = '';
}

$("#cancel_btn").on('click', function () {
    // 解密参数
    var request = JSON.parse(Base64.decode($("#request").val()));
    let tail = '';
    for(let key in request){
        if (tail == '') {
            tail += '?' + key + '=' + request[key];
        } else {
            tail += '&' + key + '=' + request[key];
        }
        console.log(key + '---' + request[key])
    }

    window.location.href = 'index'+tail;
});

$("#add_form").ajaxForm({
    dataType: "json",
    success: function (obj) {
        if (obj.errno == 0) {
            alert('添加编辑完成');
            var request = JSON.parse(Base64.decode($("#request").val()));
            let tail = '';
            for (let key in request) {
                if (tail == '') {
                    tail += '?' + key + '=' + request[key];
                } else {
                    tail += '&' + key + '=' + request[key];
                }
                console.log(key + '---' + request[key])
            }
            window.location.href = 'index' + tail;
        } else {
            alert(obj.errdesc);
        }
        return false;
    }
});

小结

base64的好处是能够存储无数个参数！一个参数，能够解决传入参数问题！
