我已阅读https://getbootstrap.com/docs/4.0/components/forms/#validation。阅读后,我想可以使用bootstrap 4默认选项在客户端站点中检查确认密码。而且,由于我是Web开发新手,所以我找不到解决方案。
如果有可能,那怎么办?
我的注册模式是
<li><button type="button" class="btn btn-light btn-lg" data-toggle="modal" data-target="#signUp">Sign Up</button></li>
<li><button type="button" class="btn btn-light btn-lg" data-toggle="modal" data-target="#signIn" style="margin-left:10px">Sign In</button></li>
<!-- Modal content-->
<div class="modal fade" id="signUp" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Sign Up</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<form>
<div class="form-group">
<label for="email" class="col-form-label">Email address:</label>
<input type="email" class="form-control" id="email" name="email">
</div>
<div class="form-group">
<label for="pwd" class="col-form-label">Password:</label>
<input type="password" class="form-control" id="pwd" name="password">
</div>
<div class="form-group">
<label for="pwd" class="col-form-label">Confirm Password:</label>
<input type="password" class="form-control" id="pwd" name="password">
</div>
</form>
</div>
<div class="modal-footer">
<button type="submit" class="btn btn-primary">Sign Up</button>
</div>
</div>
</div>
</div>

使用约束验证为的Bootstrap 4,以下形式具有两个必填字段,一个用于电子邮件地址,一个用于密码。它还具有第三个字段,只有在用户在密码字段和该第三个字段中键入相同的密码时,该第三个字段才被视为有效。
<h1>Create new account</h1>
<form action="/newaccount" method=post
oninput='up2.setCustomValidity(up2.value != up.value ? "Passwords do not match." : "")'>
<p>
<label for="username">E-mail address:</label>
<input id="username" type=email required name=un>
<p>
<label for="password1">Password:</label>
<input id="password1" type=password required name=up>
<p>
<label for="password2">Confirm password:</label>
<input id="password2" type=password name=up2>
<p>
<input type=submit value="Create account">
