需要使用javascript(或jquery)进行表单验证(所需的客户端提示) [英] need form validation using javascript(or jquery) (NEEDED CLIENT SIDE VALDATIONS)

问题描述

我是javascript和jquery的新手.我有一个发件人，其中有用户名和密码以及国家/地区文本框，还有一个下拉菜单和一个单选按钮.任何人都可以使用javascript或jquery来提供表单验证示例吗?如果用户按下提交"按钮时错误消息应该显示在名字文本框旁边，我想显示rror消息来显示名字文本框的下一个文本框示例，而无需输入名字，与下拉列表和单选框相同按钮.
