flex验证总结

最近很长时间没写博客了，主要是刚从学校回来。现在做表单定制的开发，其中涉及到了对flex中输入数据验证处理，比如email，tel，zip，当然flex中已经做的很强大，很实用。但是我们为了满足我们的需求，均对其做了继承，让变的更简单，只需要在你所验证的文本框后面加change="Validate.validate('null',event,txt1)" 即可，因为我们已经把所有的基本验证方法写成Validate这个类的validate方法，需要传参数：需要什么验证（email，tel，qq），event，text的id。然后把其打包为swc文件，最后直接引用进去就ok。很简单，:-) ，更方便以后的扩展，下面主要是代码。
