ReferenceError: GM_xmlhttpRequest is not defined
提问by Kendall Frey
I get a ReferenceError in the following userscript code:
我在以下用户脚本代码中收到一个 ReferenceError：
// ==UserScript==
// @name ...
// @namespace ...
// @description ...
// @include ...
// @grant GM_xmlhttpRequest
// ==/UserScript==
console.log(GM_info);
try
{
console.log(GM_xmlhttpRequest({ method: "GET", url: "http://google.ca/", synchronous: true }).readyState);
}
catch (e)
{
console.log(e);
}
...
It first logs GM_infosuccessfully, then logs the ReferenceError. (I'm using Firefox/Firebug.)
它首先GM_info成功记录，然后记录 ReferenceError。（我正在使用 Firefox/Firebug。）

从新闻版本（GM 4.0）开始，这个错误在你使用时发生，GM_xmlhttpRequest因为GM_xmlhttpRequest被替换为 : GM.xmlHttpRequest。

// @namespace ...
// @description ...
// @include ...
// @grant GM.xmlHttpRequest

console.log(GM_info);
try
{
console.log(GM.xmlHttpRequest({ method: "GET", url: "http://google.ca/", synchronous: true }).readyState);
}
catch (e)
{
console.log(e);
}
