当用户点击＆＃34;下一步＆＃34;当前错误消息将逐一显示。按钮，但是当用户没有在字段中输入任何数据时，我想一起显示所有三条错误消息。 电子邮件，名字和姓氏。目前，我可以逐个显示错误消息。我不想再这样做了，我想在用户点击＆＃34;下一步＆＃34;时，一起显示所有适用的错误消息。按钮。
我该怎么做？请帮帮我。
再次为无法创建js小提琴道歉。
感谢。
答案 0 :(得分：0)
您有两种选择：
1）通过附加：
，将所有错误消息收集到变量中rrrorText .= '<span class="stylish">we have toruble!</span>'
并在表格之前输出。
2）你做了一个空div：
<div id="poo"></div>
并使用javascript：
之类的内容添加错误document.getElementById('poo').innerHTML .= 'we have another problem!';
