我关注了这个link在我的本地主机上构建一个由名称和用户名组成的表单验证。
我面临的问题是，当我在两个字段都为空时单击注册时，会显示错误“该字段是必需的”，但是当我输入名称或用户名时，它会显示“确定!”红色，即使我在 label.success 下将 css 指定为绿色。
请帮忙。

}
@import url("assets/css/bootstrap.min.css");
@import url("assets/css/bootstrap-responsive.min.css");
label.valid {
font-weight: bold;
color: green;
padding: 2px 8px;
margin-top: 2px;
}
label.error {
font-weight: bold;
color: red;
padding: 2px 8px;
margin-top: 2px;

您应该在表单输入包装器上使用“has-success”、“has-warning”或“has-error”类
<div class="form-group has-success">
<label class="control-label" for="inputSuccess1">Input with success</label>
<input type="text" class="form-control" id="inputSuccess1" aria-describedby="helpBlock2">
<span id="helpBlock2" class="help-block">A block of help text that breaks onto a new line and may extend beyond one line.</span>
</div>
<div class="form-group has-warning">
<label class="control-label" for="inputWarning1">Input with warning</label>
<input type="text" class="form-control" id="inputWarning1">
</div>
<div class="form-group has-error">
<label class="control-label" for="inputError1">Input with error</label>
<input type="text" class="form-control" id="inputError1">
</div>
顺便说一下，使用 !important 不是一个好主意，目前它不受欢迎。如果你想改变标准的 Bootstrap 颜色，你应该从 SASS 或 LESS 版本编译。他们还有 mixin，允许您在自定义 HTML 类上应用 Bootstrap 样式。
关于javascript - Bootstrap 表单验证 - 颜色不变，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/39463027/
