我有一个 javascript 文件,我创建它以按以下方式工作: -它将验证在我的 html 表单字段中输入的名称和电子邮件。如果电子邮件或姓名无效,javascript 将向用户发出警报并警告他您输入的电子邮件或姓名无效。
无论如何,此警报将弹出“onBlur”。(当光标退出名称和电子邮件字段时)
我想删除“onBLur”标签。我希望在用户单击“提交”时在表单填写结束时进行验证。
怎么做?我必须用哪个标签替换“onBlur”?顺便说一句,我尝试用“onClick”替换“onBlur”:当我单击该字段以填充它时出现警报。
这是放置在我的 html 中的 head 和 /head 标记之间的 javascript **
