單擊重置時不要關閉模式-有解無憂

我不希望在單擊重置時關閉模式。它應該只是重置內部形式。但是我的代碼正在關閉模式。

uj5u.com熱心網友回復：

從您的重置按鈕中洗掉data-bs-dismiss="modal"并將其添加到您的關閉按鈕。注意：如果您希望模態框保持打開狀態，當用戶在其外部單擊時，您可以將其添加data-bs-keyboard="false" data-bs-backdrop="static"到 id="messagemodal" 的父 div

uj5u.com熱心網友回復：

雖然第一步是洗掉data-bs-dismiss屬性和值，但僅此一項并不會重置，<form>盡管它確實 - 顯然 - 阻止了模式被解除：

const modal = new bootstrap.Modal(document.getElementById('messagemodal'), {
  keyboard: false
});
modal.show();

相反，您還應該洗掉：

onclick="$('form').trigger('reset');return false;"

因為使用onclick是過時的做法，而且您使用的是 jQuery，盡管即使是原生 JavaScript 也提供了比行內事件處理程式更好的不引人注目的方法。

const modal = new bootstrap.Modal(document.getElementById('messagemodal'), {
  keyboard: false
});
modal.show();

// I'd prefer a better selector, but I'm working with what you
// have, so here we retrieve the 'reset' button and use the
// on() method to bind the anonymous function as the 
// event-handler for the 'click' event:
$('button.btn.btn-secondary').on('click', function(e){
  // here we find the closest '.modal' element:
    let modal = $(this).closest('.modal'),
      // from the .modal we find the <form> element:
        form = modal.find('form');
  // and then trigger the reset() function:
  form.trigger('reset');
})

如前所述，這在本機 JavaScript 中也很容易完成（盡管您可能出于其他原因使用 jQuery）：

const modal = new bootstrap.Modal(document.getElementById('messagemodal'), {
  keyboard: false
});
modal.show();

// caching the resetButton:
let resetButton = document.querySelector('button.btn.btn-secondary');

// binding the anonymous function of EventTarget.addEventListener() as
// the event-handler for the 'click' event:
resetButton.addEventListener('click', function(evt) {
  // caching a reference to the clicked element:
  let button = evt.currentTarget,
      // finding the closest ancestor '.modal' element:
      modal = button.closest('.modal'),
      // finding the <form> element within the .modal element:
      form = modal.querySelector('form');
  // calling the reset() function on the <form>:
  form.reset();
})

<button type="reset">此外，雖然這確實會對您的布局/演示文稿產生不利影響，但請務必記住，如果重置按鈕 ( ) 位于其內部，則重置功能不需要 JavaScript <form>，如下所示：

const modal = new bootstrap.Modal(document.getElementById('messagemodal'), {
  keyboard: false
});
modal.show();

JavaScript：
- Element.closest().
- Element.querySelector().
- Event.
- EventTarget.addEventListener().
jQuery：
- closest().
- find().
- trigger().
