I am new in appcelerator. I have a doubt. Does anybody have any idea about how to check email validation after we entered text in text field. I can able to do by a button click. But what i want is that, need to check in text field itself after text is entered. Any help will be deeply appreciated.
我是appcelerator的新手。我有个疑问。在文本字段中输入文本后,是否有人知道如何检查电子邮件验证。我可以通过点击按钮来完成。但我想要的是,需要在输入文本后签入文本字段。任何帮助将深表感谢。
Thanks

You can add a event listener on textfield.
您可以在文本字段上添加事件侦听器。
textField.addEventListener('return',function(e){
if(isValidEmail(e.source.value)){
//Email is valid
}else{
//Invalid Email
}
});
function isValidEmail(email) {
var re = /^(([^<>()[\]\\.,;:\s@\"]+(\.[^<>()[\]\\.,;:\s@\"]+)*)|(\".+\"))@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\])|(([a-zA-Z\-0-9]+\.)+[a-zA-Z]{2,}))$/;
return re.test(email);
}
