使用 bootstrap 验证重置整个表单

Question

我正在尝试使用 bootstrap 表单和验证创建仪表板。

我能够验证整个表格。

使用我当前的代码，我能够重置值但不能重置错误 class

这是我的[代码][1]

(function() {
  'use strict'
  const forms = document.querySelectorAll('.requires-validation')
  Array.from(forms)
    .forEach(function(form) {
      form.addEventListener('submit', function(event) {
        if (!form.checkValidity()) {
          event.preventDefault()
          event.stopPropagation()
        }

        form.classList.add('was-validated')
      }, false)
    })
})()

$("#resetbtn").on("click", function(e) {
  e.preventDefault();
  $('#data_input').trigger("reset");
});

删除已验证

您的脚本将受益于一直使用 jQuery

如果您将表单操作设置为您想要的页面并删除 method="post" 以获得默认的 GET 方法，当表单正常时页面将发生变化

$(function() {
  'use strict'
  $('#data_input').on('submit', function(event) {
    if (!event.target.checkValidity()) {
      event.preventDefault()
      event.stopPropagation()
    }
    $(this).addClass('was-validated'); //inside the else or not
  });
  $("#resetbtn").on("click", function(event) {
    event.preventDefault();
    $('#data_input')
      .trigger("reset")
      .removeClass('was-validated')
  });
});

$(function() {
  'use strict'
  $('#data_input').on('submit', function(event) {
    if (!event.target.checkValidity()) {
      event.preventDefault()
      event.stopPropagation()
    }
    $(this).addClass('was-validated')
  });
  $("#resetbtn").on("click", function(event) {
    event.preventDefault();
    $('#data_input')
      .trigger("reset")
      .removeClass('was-validated')
  });
});
