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。

1 个答案:

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!';
