Html5表单验证不适用于iphone，android或safari
我正在尝试为我的网络应用程序实现html5表单验证，但它不能使用
safari 5.0.1，iphone3或android2。这些浏览器是否支持表单输入属性，模式或与验证相关的任何内容，或者我犯了一些错误？
I am trying to implement html5 form validation for my web app but it's not working with safari 5.0.1 , iphone3 or android2. Is the form input attribute required, pattern or anything related to validation not supported by these browsers or i am making some mistake?
它正在使用mozilla，chrome和opera。如果我使用html5表单验证，那么我再次需要编写代码作为后备。使用这个或更老的方式作为jquery和普通的javascript是一个好主意？如果有任何想法请告诉我。
It's working with mozilla, chrome and opera. If i use html5 form validation then again i need to write code as fallback. Is it a good idea to use this or the older way as jquery and plain javascript? If any one have idea please tell me.
请检查此链接（我写了一些代码）并在iphone，android或safari中试用：

如果您正在使用jQuery，可以查看 h5Validate插件。这为IE6增加了对表单验证的跨浏览器支持。根据项目网站：
If you're using jQuery, you could take a look at the h5Validate plugin. This adds cross-browser support for form validations down to IE6. According to the project's website:
