我的Bootstrap 4 form validation发生了一件令人讨厌的事情,其中有两个单选按钮,当表单经过验证时,其标签的前景会变为绿色。如果表单无效,则标签不会变为红色。无论哪种方式,他们应该坚持他们的黑色前景,因为单选按钮输入没有像我的其他表单元素那样与他们相关联的required
属性。为什么它们会变为绿色,我如何防止这种情况或停止在这两个实体上进行表单验证?
的index.html
<form id="signup-form" novalidate>
<div class="form-group">
<h1>Sign Up</h1>
<p>Use this form to enter your name and email to sign up.</p>
</div>
<!-- Name -->
<div class="form-group">
<div class="row">
<div class="col">
<label for="firstNameInput">Name</label>
<input type="text" class="form-control" id="firstNameInput" placeholder="First name" required>
<div class="valid-feedback">
Looks good!
</div>
</div>
<div class="col">
<label for="lastNameInput">Last</label>
<input type="text" class="form-control" id="lastNameInput" placeholder="Last name" required>
<div class="valid-feedback">
Looks good!
</div>
</div>
</div>
</div>
<!-- Email -->
<div class="form-group">
<label for="emailAddressInput">Email address</label>
<input type="email" class="form-control" id="emailAddressInput" aria-describedby="emailHelp" placeholder="name@example.com" required>
<small id="emailHelp" class="form-text text-muted">We'll never share your email with anyone else.</small>
<div class="invalid-feedback">
Please provide a valid email.
</div>
</div>
<!-- Options -->
<div class="form-group">
<div class="form-check">
<input class="form-check-input" type="radio" name="Radios" id="type1RadioButton" value="option1" checked>
<label class="form-check-label" for="type1RadioButton">
Type 1 user
</label>
</div>
<div class="form-check">
<input class="form-check-input" type="radio" name="Radios" id="type2RadioButton" value="option2">
<label class="form-check-label" for="type2RadioButton">
Type 2 user
</label>
</div>
</div>
<!-- Submit Button -->
<div class="form-group">
<a href="#" class="btn btn-primary" id="submitButton" type="submit">Submit</a>
</div>
</form>
的script.js
$(document).ready(function() {
$("#submitButton").click(function() {
//Fetch form to apply custom Bootstrap validation
var form = $("#signup-form")
alert(form.prop('id')) //test to ensure calling form correctly
if (form[0].checkValidity() === false) {
event.preventDefault()
event.stopPropagation()
}
form.addClass('was-validated')
})
})
结果
在表单验证之前
表单验证后
答案 0 :(得分:3)
使用HTML5验证表单时,:valid
状态(或验证失败时为:invalid
)将应用于所有表单输入。我不知道如何防止:将有效状态应用于特定输入。
一旦:valid
应用于输入,Bootstrap就会有这个CSS,使标签变为绿色......
.was-validated .form-check-input:valid~.form-check-label {
color: #28a745;
}
要覆盖Bootstrap正在应用的绿色样式,请使用标签上的text-dark
类。这样标签将始终为黑色,而不是绿色(:有效)或红色(:无效)。
