在 Quilljs 2.0.* 中如何使用寄存器而不是格式？

Question

在quill 1.x中，我们可以使用formats来配置需要的格式：

var quill = new Quill('#editor-container', {
  modules: {
    toolbar: false
  },
  placeholder: 'Compose an epic...',
  formats: ['bold', 'italic', 'link', 'strike', 'script', 'underline'],
  theme: 'snow'  // or 'bubble'
});

但是，quill 2.0 删除了格式

upgrading-to-2-0.md：删除格式 - 注册表现在更加强大和安全。

如何使用寄存器而不是格式？

Answer 1

根据this issue，quill 2的formats问题仍然悬而未决，似乎没有人跟进。

根据 this issue，无法注销特定注册表。唯一的方法是覆盖它们，但是当我尝试向 ScrollBlot 为 null 且无法成功初始化的选项提供新的 Registry 时出现错误。

要禁用格式，唯一的方法是扩展格式 class 并再次注册以覆盖默认行为。

禁用粗体

const Bold = Quill.import('formats/bold');

// extends format class (Bold) to override its methods
class CustomBold extends Bold {
   // override: return false to avoid formatting again
   static formats() { return false; }
   // override: empty content to avoid bolt name replacement
   optimize(context) { }
}
// remove all tag names (strong, b)
CustomBold.tagName = [];

// register the new custom bold formatting
Quill.register({ 'formats/bold': CustomBold })

具有所有格式的完整版
