如何从函数中禁用 jQuery 对话框中的按钮？ - How can I disable a button in a jQuery dialog from a function?

问题：

I have a jQuery dialog that requires the user to enter certain information.我有一个 jQuery 对话框，需要用户输入某些信息。 In this form, I have a "continue" button.在这种形式中，我有一个“继续”按钮。 I would like this "continue" button to only be enabled once all the fields have content in them, else it will remain disabled.我希望这个“继续”按钮只有在所有字段都包含内容后才启用，否则它将保持禁用状态。

I wrote a function that is called everytime a field status has changed.我编写了一个函数，每次字段状态发生变化时都会调用该函数。 However, I don't know how to enable and disable the dialog button from this function.但是，我不知道如何从此功能启用和禁用对话框按钮。 What should I do?我该怎么办？

Oops and I forgot to mention that these buttons were created as follows:哎呀，我忘了提到这些按钮是按如下方式创建的：

$(function() {
  $("#dialog").dialog({
    bgiframe: true,
    height: 'auto',
    width: 700,
    show: 'clip',
    hide: 'clip',
    modal: true,
    buttons: {
      'Add to request list': function() {
        $(this).dialog('close');
        $('form').submit();
      },
      'Cancel': function() {
        $(this).dialog('close');
      }
    }
  })
});
