how to create a ActiveXObject with node.js?
提问by cybertextron
I'm a totally newbie in node.js. I'm trying to implement a browser performance tool using node.js, so I have the following piece of code:
我是node.js. 我正在尝试使用 node.js 实现浏览器性能工具，所以我有以下代码：
for(var j=0; j < 14; j++) {
// Create a new instance of HttpWatch in Firefox
var control = new ActiveXObject('HttpWatch.Controller');
var plugin = control.Firefox.New();
// Start Recording HTTP traffic
plugin.Log.EnableFilter(false);
// Clear Cache and cookier before each test
plugin.ClearCache();
plugin.ClearAllCookies();
plugin.ClearSessionCookies();
plugin.Record();
// Goto to the URL and wait for the page to be loaded
plugin.GotoURL(url);
control.Wait(plugin, -1);
// Stop recording HTTP
plugin.Stop();
if ( plugin.Log.Pages.Count != 0 )
{
// Display summary statistics for page
var summary = plugin.Log.Pages(0).Entries.Summary;
//WScript.Echo( "Iteration number " + j + "for" + url + " Total time to load page in (secs): " + summary.Time);
cache[i].value.push(summary.Time);
}
// Close down Firefox
plugin.CloseBrowser();
}
I'm using httpwatchto measure the performance values, which are going to be stored in a MySQLdatabase.
However, when I run:
我正在使用httpwatch来测量性能值，这些值将存储在MySQL数据库中。但是，当我运行时：
node test.js
I get:
我得到：
C:\xampp\htdocs\test\browser-perf>node test.js
C:\xampp\htdocs\test\browser-perf\test.js:37
var control = new ActiveXObject('HttpWatch.Controller');
^
ReferenceError: ActiveXObject is not defined

How can I create a similar object as ActiveXObjectin node.jsand obtain the same desired results?
我怎样才能创建一个类似的对象ActiveXObject中node.js，并获得同样的预期效果？

I'm not a node.js user, so I can't comment on node.js specifically, but ActiveXObjectis a feature of the Microsoft Active Scripting JScript engine, as well as the new Chakra engine in IE9, so it is not available in other platforms because it's very Windows-specific.
我不是node.js用户，所以不能具体评论node.js，但它ActiveXObject是Microsoft Active Scripting JScript引擎的一个特性，以及IE9中新的Chakra引擎，所以它在其他平台，因为它非常特定于 Windows。

As in https://github.com/mynetx/codebird-js/issues/13, you can emulate it using xhr2: https://npmjs.org/package/xhr2.
正如在https://github.com/mynetx/codebird-js/issues/13 中一样，您可以使用xhr2：https: //npmjs.org/package/xhr2模拟它。
npm install xhr2
I'm not sure if that will work for your browser performance tool but at least for someone else googling on the ActiveXObjecterror it should work.
我不确定这是否适用于您的浏览器性能工具，但至少对于谷歌搜索ActiveXObject它应该工作的错误的其他人。
