Question

我抓住了一个登录页面模板，在我的网站上实现，并根据登录页面模板创建了一个注册页面。我遇到了实际按钮点击的问题。当我将鼠标悬停在按钮上时，它会改变颜色，但当您将鼠标悬停在链接/按钮上时，鼠标指针不会切换手指。当我点击按钮时没有任何反应。我有一个php文件设置来检查字段，然后将信息提交到数据库中。这是代码：

Answer 1

使用

<form method="post" action="register.php" autocomplete="on">

错误是<form action="javascript:void(0);" method="post" action="register.php" autocomplete="on">

形式的两个操作属性

Answer 2

我重写了编码。你可以使用它们。我删除了多个操作。我使用占位符代替 value =＆＃34;用户名＆＃34; onBlur =＆＃34; if（this.value ==＆＃39;＆＃39;）this.value =＆＃39;用户名＆＃39;＆＃34; onFocus =＆＃34; if（this.value ==＆＃39;用户名＆＃39;）this.value =＆＃39;＆＃39;＆＃34; 。此外，我们不得使用 value =＆＃34;名字＆＃34; 。现在您已经编写了所有值。它会影响表单验证。
