首先尝试使用 真正的 Javascript 进行投票！
其次，您可能没有意识到，但是您将代码视为文本，而不是代码。不要使用
innerHTML也不要使用
responseText。您需要使用适当的DOM方法，例如
appendChild，
insertBefore尽管使用AJAX，您需要专门使用
importNode和
responseXML。从服务器加载的XML
必须 用作
application/xml，而mime
text/xml无效。
我网站上的代码可用于较旧的浏览器（例如IE5 /
6，如果您此时如此疯狂）。我一直想清理这个。此外，它是可重用的，因此您无需继续创建新的AJAX函数，除非
ajax_post()您访问我的网站并查看
index.js文件，否则您可以将其弄乱。
超级奖金： 该
ajax_sequel()功能可用于在AJAX请求完全完成 后 执行所需的任何操作。我将
alerts
留在原处，让您弄乱代码。
执行示例…
ajax_load_page('?ajax=1&url=mail/sent/','inside','sidebar','sequel-string',id_focus);第一个参数是AJAX URL，请记住，您 必须 具有单个元素，其中包含请求的 所有内容 ，并且在请求之前或之后都没有空格。它必须 也
有一个XML命名空间…
<div xmlns="http://www.w3.org/1999/xhtml">AJAX stuffs</div>
第二参数接受字符串
after，
before，
inside，
replace相对于所述第三参数的id。
ajax_sequel()我已经提到的函数使用的第四个参数。
最后一个（第五个）参数是我希望浏览器重点关注的ID（如果有）。
严格的代码很难，但是如果您以正确的方式进行操作，事情就会变得容易得多。
缺少的任何功能都可以在
index.js我的网站文件中找到，该文件通过我的个人资料链接。这是您要寻找的主要内容…
