" AJAX" - 发送但不需要回复？ [英] "AJAX" - sending but don't need response?
问题描述
我有一种情况需要发送数据，但我不需要
响应。在我看来，XMLHTTPRequest是发送
数据的最佳方式，但我不需要从服务器回复任何响应。
基本上，我正在将js错误写入服务器端的错误日志 -
并且无需通知用户错误已被记录。
问题是我不想坐在请求打开和放大等待
作为回复，当我不需要回复时。我想我可以
服务器响应只是OK或类似的东西，但是它的确是不相关的b $ b
我在考虑只是在readystate = 1中删除请求（在那个
点，服务器端脚本应该已经执行了，对吧？），但是
我想知道是否还有其他方法可以发送..
Thanx
I have a situation where I want to send data, but I have no need for a
response. It seems to me that XMLHTTPRequest is the best way to send the
data, but I don''t need any response back from the server.
Basically, I''m writing js errors to an error log on the server side -
and there is no need to inform the user that the error has been logged.
The problem is that I don''t want to sit with the request open & waiting
for a response, when I have no need for the response. I suppose I could
have the server respond with just "OK" or something like that, but it''s
really not relevant
I was thinking of just aborting the request on readystate=1 (at that
point, the server-side script should have executed already, right?), but
I was wondering if there were any other methods to JUST send..
Thanx

Not一个脚本问题。请参阅HTTP规范，204 /无内容响应
Not a script question. See HTTP specs, 204 / No Content response

否，XMPHTTPRequest不是发送数据的最佳方式。特别是
，因为你不需要回复。
myVar = new Image（）;
myVar.src = " pathToServerSideScript.ext" + errorMessage;
然后服务器端脚本执行，没有任何响应。
这是如此广泛的问题，它在常见问题：

No, XMPHTTPRequest is not the best way to send the data. Especially
since you don''t need the response.
myVar = new Image();
myVar.src = "pathToServerSideScript.ext?" + errorMessage;
Then the server side script executes and nothing is done with the response.
This is so widely asked that its in the FAQ:

这个老技巧总能奏效，但这只是一个技巧，我认为XHR是正确的方式
这样做。除了查询字符串也有一个
大小限制这一事实，所以这个技巧也不是发送数据的最佳方式。
如果你不需要发送大量数据，或者如果你需要
与旧浏览器的兼容性，那么......使用查询字符串。
否则我全都是XHR \ o /，因为对我来说这显然是正确的方式，
如果回复对你没关系，甚至不会产生它！由于
你只需要检查标题（有一种方法可以在这个XHR对象上获取
标题，但我认为它不存在于IE，搜索一下
小嘿嘿）。
