这是我的 JSP 页面。我已经完成了一次验证，它取决于提交按钮，即，如果有任何验证失败，它将检查并抛出错误消息，但我希望它在运行中，即，将进入自己。所以请帮助我!
最佳答案
为您的电子邮件文本字段提供 id 属性并使用我的代码:
$(document).ready(function(){
$("#email").keyup(function(){
var email = $(this).val();
// here you can validate email and show alert or show message into your error box.
var pattern=/^(([^<>()[\]\\.,;:\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,}))$/;
if(pattern.test(email)){
$("#errmsgbox").html("Valid email address");
}else{
$("#errmsgbox").html("Please enter valid email address");
}
});
});
关于javascript - 我想在输入数据时显示一条错误消息(在 keyup 上)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/34850981/
