我添加了三个验证消息。当我单击提交按钮时，所有三个消息都显示在 div 中。

有没有办法一次显示一条消息（优先级副或哪个先出现。）

代码：

<div class="col-md-6">
    <input class="form-control" type="password" id="<isprint value="#NewPasswordForm:Password:QualifiedName#">" name="<isprint value="#NewPasswordForm:Password:QualifiedName#">" placeholder="Password" data-bv-notempty="true"
                required data-bv-notempty-message="<istext key="account.user.new.password.error.required"/>"
                data-bv-identical="true"
                data-bv-identical-field="<isprint value="#NewPasswordForm:ConfirmPassword:QualifiedName#">"
                data-bv-identical-message="<istext key="account.user.new.password.error.confirm_Password"/>"
                data-bv-regexp="true"
                data-bv-regexp-regexp="^(?=[^\s]*[a-zA-Z])(?=[^\s]*[\d])[^\s].{7,256}$"
                data-bv-regexp-message="<istext key="account.create_user.password.error.regexp"/>"
                />

和按空格后的 HTML 代码。

<div class="col-md-6">
<input id="NewPassword_Password" class="form-control" type="password" data-bv-regexp-message="The password must be at least 7 characters in length." data-bv-regexp-regexp="^(?=[^\s]*[a-zA-Z])(?=[^\s]*[\d])[^\s].{7,256}$" data-bv-regexp="true" data-bv-identical-message="The password and its confirm are not the same." data-bv-identical-field="NewPassword_ConfirmPassword" data-bv-identical="true" data-bv-notempty-message="The password is required and cannot be empty." required="" data-bv-notempty="true" placeholder="Password" name="NewPassword_Password" data-bv-field="NewPassword_Password">
<i class="form-control-feedback glyphicon-remove glyphicon" style="" data-bv-icon-for="NewPassword_Password"></i>
<small class="help-block" style="" data-bv-validator="identical" data-bv-for="NewPassword_Password" data-bv-result="INVALID">The password and its confirm are not the same.</small>
<small class="help-block" style="" data-bv-validator="notEmpty" data-bv-for="NewPassword_Password" data-bv-result="INVALID">The password is required and cannot be empty.</small>
<small class="help-block" style="" data-bv-validator="regexp" data-bv-for="NewPassword_Password" data-bv-result="INVALID">The password must be at least 7 characters in length.</small>
</div>

请提供一些意见。

你可以用 css 隐藏它们：

small.help-block {
  display: none;
}

small.help-block:first-of-type {
  display: block
}

请看看插件作者（Phuoc Nguyen）如何处理 - http://bootstrapvalidator.com/examples/changeing-default-behaviour/#showing-one-message-each-time

基本上，诀窍是监听验证错误事件并隐藏除最后一个验证器检查之外的所有错误消息：

    .on('error.validator.bv', function(e, data) {
        // $(e.target)    --> The field element
        // data.bv        --> The BootstrapValidator instance
        // data.field     --> The field name
        // data.element   --> The field element
        // data.validator --> The current validator name

        data.element
            .data('bv.messages')
            // Hide all the messages
            .find('.help-block[data-bv-for="' + data.field + '"]').hide()
            // Show only message associated with current validator
            .filter('[data-bv-validator="' + data.validator + '"]').show();
    });

所有代码（我假设）都是由插件作者本人 - Phuoc Nguyen https://github.com/nghuuphuoc
