在显示的模态中有一个表格。如果我专注于输入字段（与此相关的任何字段）并按 ESC 键，则该模式将被隐藏。但是，如果我不关注表单字段，则按 ESC 键不会关闭模式。这是怎么回事？

我想完全禁用模式的 ESC 键功能。我试过这个：

$(document).on('keypress', function(e) {
  if(e.keyCode == 27) {
    e.preventDefault();
    return false;
  }
}

但这不会影响任何事情。有没有办法完全禁用模式的 ESC 键？

通过添加data-keyboard="false"修复问题。

像这样的东西：<div class="modal hide fade" data-keyboard="false" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">

Twitter 的 Bootstrap modal.js（参见http://getbootstrap.com/2.3.2/javascript.html#modals）本身具有键盘 true 或 false 布尔值。您可以使用以下脚本避免转义键并在模式外单击：

    $(function () {
        $('.modal').modal({
            show: true,
            keyboard: false,
            backdrop: 'static'
        });
    });

工作演示：

$(function () {
     $('.modal').modal({
      show:true,
      keyboard: false,
      backdrop: 'static'
    });
});

如果您的模态对话框看起来像这样

<div id="myModal" class="modal hide fade" tabindex="-1" ...>
   ....
</div>

删除tabindex="-1"应该禁用 Escape 键。

你需要 data-keyboard="false"并且data-backdrop="static"

工作演示：

将键盘值设置为 false！

例子：

<a data-controls-modal="myModal"
   data-backdrop="static"
   data-keyboard="false"
   href="#">

或者，如果您使用的是 JavaScript：

$(function () {
$('.modal').modal({
  backdrop: 'static',
  keyboard: false
});
}

> 键盘：真

 按下退出键时关闭模式。

> 键盘：假

 按下退出键时防止关闭模态

演示 jQuery 代码

$('#myModal').modal({show: true, keyboard: false});

您可以通过向其添加 ID 并简单地删除 keydown 事件来定位该特定输入，如下所示：

JS

$(document).ready(function() {
  $('form input').keydown(function(event){
    if(event.keyCode == 13) {
      event.preventDefault();
      return false;
    }
  });
});

此示例使用 Enter 键。
