jQuery的1.5版本 - AJAX - ＆LT;脚本＆GT;标记时间戳问题 [英] jQuery version 1.5 - ajax - <script> tag timestamp problem
问题描述
如果我加载使用AJAX（jQuery的）一些内容已在它的脚本标记，jQuery的1.5增加了时间戳script标签的src URL。见例如波纹管。
If I load some content with ajax (jQuery) which has a script tag in it, jQuery 1.5 adds the timestamp to the script tag src url. See example bellow.
例： 内容我加载使用AJAX：
Example: content what I load with ajax:
<div>text1</div>
<script type="text/javascript" src="/js/abc-xyz.js?r=1.1"></script>
这是从它加载脚本code后，我插入了previous内容到页面的src网址：
This is the src url from where it loads the script code after I insert the previous content to the page:
.../js/abc-xyz.js?r=1.1&_=1297892228466
有谁知道为什么会这样呢？ 这种事只使用jQuery 1.5。它不会发生与jQuery 1.4.4。
Does anybody knows why this happening? It happens only with jQuery 1.5. It doesn't happen with jQuery 1.4.4.
code例：
$.ajax({
url: content.html,
type: 'GET',
data: someDataObject,
success: function(data) {
// some code here
},
error: function(data) {
// some code here
}
});
感谢。

答：
检查您的报告，您的code样品后，我得出的结论是，这是不是一个错误。我还做了这个测试用例的jQuery 1.4+（至1.5）有这引起了缓存选项不是一个bug默认为false，脚本的请求。这个bug（见＃7578 ）已被固定在1.5。 现在，你可能知道或不知道的是，那做jQuery的DOM操作（以prevent某些错误在IE浏览器）时，不特殊处理脚本标记。它过滤出来，并通过AJAX请求它们。这就解释了为什么即使是正常的内联脚本标记突然被要求额外的URL参数。 有办法解决这个如果有有害的副作用你。
After checking your report and your code samples I come to the conclusion that this isn't a bug. I also made this test case jQuery 1.4+ (until 1.5) had a bug which caused the cache option not to default to false for script requests. This bug (see #7578) has been fixed in 1.5 . Now what you might know or not know is, that jQuery does special-handle script tags when doing DOM manipulations (to prevent certain errors in IE). It filters them out and requests them via ajax. This explains why even a "normal" inline script tag suddenly is requested with additional url parameters. There are ways to work around this if it has unwanted side effects for you.

使用$ .ajaxSetup（{缓存：真}）在适当的时候
use $.ajaxSetup({ cache: true }) when appropriate
使用 prefilter 脚本请求而如检查URL地址不想要 要添加的随机参数，设置高速缓冲存储器：在prefilter对那些真正
use a prefilter for script requests and e.g. check for urls where you don't want the random parameter to be added and set cache: true in the prefilter for those
在如成功的回调处理脚本通过做一些沿着这些路线标签自己 VAR elems = $（htmlwithscripttags）; elems.filter（脚本）//现在做任何的脚本 elems.filter（：不是（脚本））appendTo（身体）。 //e.g。
in e.g. the success call back handle the script tags yourself by doing something along these lines var elems = $(htmlwithscripttags); elems.filter("script") //now do whatever with the scripts elems.filter(":not(script)").appendTo("body"); //e.g.
