I belive Pocket IE support Java Script.Microsoft Pocket IE Browser comes as a part of the Pocket PC SDk, and it’s also a free download. It has most of the features of Desktop IE browser. Some of the un supported internet technology of Pocket IE are MIDI, AU, and AIFF sound files, Netscape plug-ins, Newsgroups and Style Sheet. Pocket IE also don’t support HTML tags like APPLET, BLINK, ISINDEX, OBJECT, STYLE.
最好不要用JAVASCRIPT,因为你所面对的客户端都不会一样。
用MICROSOFT提供的控制在服务器端进行处理就好了,它会自动为不同的客户端生成不同的代码。
