Question

请查看下面列出的html，让我知道为什么IE6在尝试加载远程脚本（位于“http://code.katzenbach.com/Default.aspx”时）时会冻结。该脚本返回JSONP并执行标头中列出的'callbackFunction'。当它正确运行时，您将看到一个弹出警报，显示数字1-500。这在FF3和IE7中工作正常。我无法理解为什么它在Internet Explorer 6中失败 - 处理器被挂起并且一切都挂起。

自己运行并告诉我您是否遇到同样的问题。我一整天都在盯着这个问题。谢谢你的帮助。

Answer 1

我看了Fiddler和IE6并且看不到任何异常（除了冻结浏览器的事实）。

http://code.katzenbach.com/Default.aspx?callback=callbackFunction&test=true&c=500的请求确实发出并返回2909字节。

我建议三件事：

从您的内容类型中移除一个分号：application/json;; charset=utf-8或者可以完全删除分号和charset=utf-8（仅用于测试）
发送) callbackFunction

Content-Type: text/javascript

将其更改为{{1}}，因为您确实将Javascript返回到浏览器，而其他内容类型可能会让IE6感到困惑（尽管不太可能）。

我在想1.最有可能。 IE6中可能存在一个解析错误，当它遇到两个分号时会导致它进入无限循环。因为否则就没有任何理由说明你为什么不应该工作。

尝试使用不同的MIME类型作为测试也是值得的。

外部脚本的返回是：

callbackFunction(["0","1","2","3","4","5","6","7","8","9","10","11","12","13","14","15","16","17","18","19","20","21","22","23","24","25","26","27","28","29","30","31","32","33","34","35","36","37","38","39","40","41","42","43","44","45","46","47","48","49","50","51","52","53","54","55","56","57","58","59","60","61","62","63","64","65","66","67","68","69","70","71","72","73","74","75","76","77","78","79","80","81","82","83","84","85","86","87","88","89","90","91","92","93","94","95","96","97","98","99","100","101","102","103","104","105","106","107","108","109","110","111","112","113","114","115","116","117","118","119","120","121","122","123","124","125","126","127","128","129","130","131","132","133","134","135","136","137","138","139","140","141","142","143","144","145","146","147","148","149","150","151","152","153","154","155","156","157","158","159","160","161","162","163","164","165","166","167","168","169","170","171","172","173","174","175","176","177","178","179","180","181","182","183","184","185","186","187","188","189","190","191","192","193","194","195","196","197","198","199","200","201","202","203","204","205","206","207","208","209","210","211","212","213","214","215","216","217","218","219","220","221","222","223","224","225","226","227","228","229","230","231","232","233","234","235","236","237","238","239","240","241","242","243","244","245","246","247","248","249","250","251","252","253","254","255","256","257","258","259","260","261","262","263","264","265","266","267","268","269","270","271","272","273","274","275","276","277","278","279","280","281","282","283","284","285","286","287","288","289","290","291","292","293","294","295","296","297","298","299","300","301","302","303","304","305","306","307","308","309","310","311","312","313","314","315","316","317","318","319","320","321","322","323","324","325","326","327","328","329","330","331","332","333","334","335","336","337","338","339","340","341","342","343","344","345","346","347","348","349","350","351","352","353","354","355","356","357","358","359","360","361","362","363","364","365","366","367","368","369","370","371","372","373","374","375","376","377","378","379","380","381","382","383","384","385","386","387","388","389","390","391","392","393","394","395","396","397","398","399","400","401","402","403","404","405","406","407","408","409","410","411","412","413","414","415","416","417","418","419","420","421","422","423","424","425","426","427","428","429","430","431","432","433","434","435","436","437","438","439","440","441","442","443","444","445","446","447","448","449","450","451","452","453","454","455","456","457","458","459","460","461","462","463","464","465","466","467","468","469","470","471","472","473","474","475","476","477","478","479","480","481","482","483","484","485","486","487","488","489","490","491","492","493","494","495","496","497","498","499"])

Answer 3

如果直接转到脚本（http://code.katzenbach.com/Default.aspx?callback=callbackFunction&test=true&c=500），您将看到未处理文件（未知的mime类型）。这可能是由于您的服务器设置问题。它似乎不知道如何处理.aspx而是试图流出文件。

为什么这个远程脚本导致IE6挂起？
