JavaScript的：阅读使用AJAX文本文件文本文件、JavaScript、AJAX
不能让AJAX工作！我有一个网站，一个大帐篷，得到它的工作！但我想它找到一个文本文件字幕的文字，我想它读取文本文件中的文本（这是一条线），并将其分配给名为含量，这是在脚本标记的全局变量。
Can't get AJAX to work! I have a marquee on a website, got it working! But I want it to find the text of the marquee in a text file, and I want it to read the text in the text file (which is one line) and assign it to the variable called content, which is a global variable in the script tag.
在我所经营的网站（本地IIS），字幕文字是：未定义（不带引号）
When I run the website (local IIS), the marquee text is: "undefined" (without the quotes).
为什么不将其分配文本变量内容？
Why isn't it assigning the text to the variable content?
var content
function loadXMLDoc()
{
var textfile;
if (window.XMLHttpRequest)
{
textfile = new XMLHttpRequest();
}
textfile.onreadystatechange = function ()
{
if (textfile.readyState == 4 && textfile.status == 200)
{
content = textfile.responseText;
}
}
textfile.open("GET", "C:\Users\Fares\Dropbox\Sync\College\Computing\DeltaOne\MarqueeText.txt", true);
textfile.send();
}

A million thanks to @kuncajs, as he pointed out I forgot to call the function! :) Fixed! Thanks to everyone else!
推荐答案
不要使用类似本地路径：
C：\ Users \用户票价\ Dropbox的\同步\学院\计算\ DeltaOne \ MarqueeText.txt
Do not use local paths like:
C:\Users\Fares\Dropbox\Sync\College\Computing\DeltaOne\MarqueeText.txt
将它放在你的IIS的www目录并说明喜欢的路径：
本地主机/的text.txt
Place it in the www directory of your IIS and state the path like:
localhost/text.txt
服务器可以限制访问您的文件系统，你也应该尝试像的text.txt 相对路径或绝对路径 /text.txt 这样的路径，当你将其部署在生产环境中工作，甚至。
The server can have restricted access to your filesystem and also you should try relative paths like text.txt or absolute paths /text.txt so the paths work even when you deploy it in the production environment.
编辑：
因此，如果这没有帮助，那么要确保你真的叫 loadXMLDoc（）把功能。另外，请检查你做的一切都是的在的AJAX的结束！我的意思是你做任务的，如果 - ！当AJAX做，但你也应该初始化选取框后！文字是加载。如果你这样做之前，它是不确定的。
So if this did not help then make sure that you really call the loadXMLDoc() function. Also check that everything you do is after the AJAX ends! I mean you do the assignment in the if - when AJAX is done but you should also initialize your marquee !AFTER! the text is loaded. If you do it before it will be undefined
