【中文标题】Jquery - 如何删除复选框和收音机上的多个味精返回【英文标题】:Jquery - How do I remove multiple msg return on checkboxes and radio 【发布时间】:2012-06-07 13:27:53 【问题描述】:感谢这个论坛上的人们,我在代码工作中遇到了主要的痛苦,但我遇到了一些问题。
验证复选框/单选字段时,返回消息会针对每个未选中的单选/复选框给我一个响应。返回信息应该只是说一个'请填写1433'不是 请填写1433 请填写1433 请填写1433【群内每张支票/单选一条留言】
在这个继承的代码中,我实际上会将字段的名称添加到类中,但是在确定未选择所需的检查/无线电组中的任何内容后,我如何只获得一个消息?

【问题讨论】:
【参考方案1】:这是一个轻微的修改,首先创建一个空数组。在each
循环中,它会检查名称是否已经在数组中,如果没有,它将错误写入页面并将名称添加到数组中
