我在Drupal论坛发布了一个类似的问题，但是我没有太多的运气。 我正在将站点从D6升级到D7。到目前为止，它进展顺利，但我得到了一个Javascript错误，我无法为其解决方案。 这是整个剧本的削减版本：升级到Drupal 7后出现Javascript错误
(function($) {
function sign(secret, message) {
var messageBytes = str2binb(message);
var secretBytes = str2binb(secret);
if (secretBytes.length > 16) {
secretBytes = core_sha256(secretBytes, secret.length * chrsz);
}
var ipad = Array(16), opad = Array(16);
for (var i = 0; i < 16; i++) {
ipad[i] = secretBytes[i]^0x36363636;
opad[i] = secretBytes[i]^0x5C5C5C5C;
}
var imsg = ipad.concat(messageBytes);
var ihash = core_sha256(imsg, 512 + message.length * chrsz);
var omsg = opad.concat(ihash);
var ohash = core_sha256(omsg, 512 + 256);
var b64hash = binb2b64(ohash);
var urlhash = encodeURIComponent(b64hash);
return urlhash;
}
function addZero(n) {
return (n < 0 || n > 9 ? "" : "0") + n;
}
Date.prototype.toISODate =
new Function("with (this)\nreturn " +
"getFullYear()+'-'+addZero(getMonth()+1)+'-'" +
"+addZero(getDate())+'T'+addZero(getHours())+':'" +
"+addZero(getMinutes())+':'+addZero(getSeconds())+'.000Z'");
function getNowTimeStamp() {
var time = new Date();
var gmtTime = new Date(time.getTime() + (time.getTimezoneOffset() * 60000));
return gmtTime.toISODate() ;
}
}(jQuery));
是不断抛出我看到萤火虫的错误的部分是：
Date.prototype.toISODate =
new Function("with (this)\n return " +
"getFullYear()+'-'+addZero(getMonth()+1)+'-'" +
"+addZero(getDate())+'T'+addZero(getHours())+':'" +
"+addZero(getMinutes())+':'+addZero(getSeconds())+'.000Z'");
萤火虫一直停在“addZero不定义”。 JS从来就不是我的强项，我知道D7已经做了一些改变。我已经将整个脚本包装在“（function（$）{}（jQuery））;”中，但我必须缺少其他的东西。相同的脚本在D6站点上完美工作。
以下是添加了@Pointy建议的整个代码的“固定”版本。我所遗漏的是制作散列到亚马逊的脚本的一部分，以及我声明的一些变量。

控制台中的错误说了什么？ – 2012-02-10 13:49:38
我试图通过去除串联来简化函数 - 连接内部的串联比Inception更能伤害我的大脑。 http://jsfiddle.net/ExvRS/我得到一个关于内部函数的undef，也许检查那些被定义和导入的，并且在他们被调用的时候也准备好了。 – 2012-02-10 13:52:51
这很可怕。为什么这样写？ – Pointy 2012-02-10 13:52:55
