奇怪的jQuery的查询字符串追加 [英] Weird jQuery query string appended
问题描述
能解释一些什么_的价值是怎么一回事?这是小提琴手是显示我有客户端上的jQuery的Ajax调用我的MVC 3页。
Can some explain what the "_" value is all about? This is what fiddler is showing me for my MVC 3 page that has a jQuery ajax call on the client.
GET /服务/ GetFoodDescriptionsLookup(100)?_ = 1291727469299 HTTP / 1.1
GET /Services/GetFoodDescriptionsLookup(100)?_=1291727469299 HTTP/1.1
在网址构建以这种方式,我不回来任何数据,但如果我键入
When the URL is constructed in this fashion I don't get back any data, but if I type
GET /服务/ GetFoodDescriptionsLookup(100)
GET /Services/GetFoodDescriptionsLookup(100)

推荐答案
它是由jQuery的加入到prevent缓存时的 缓存:假
设置。这基本上是IE的,不会重新提交一个AJAX GET请求(除非极其配置以及缓存策略)过于急切的高速缓存的解决方法。
It's added by jQuery to prevent caching when cache:false
is set. This is basically a workaround for IE's over-eager caching that will not resubmit an AJAX GET request (unless the caching policy is extremely well-configured).
