vue Quill富文本工具栏自定义行高

 import Quill from 'quill' let Parchment = Quill.import('parchment');
   // 设置行高为style 设置为class回显富文本时会失效   // class lineHeightAttributor
   extends Parchment.Attributor.Attribute {}  // Attribute // class
   lineHeightAttributor extends Parchment.Attributor.Class {}  // Class
   class lineHeightAttributor extends Parchment.Attributor.Style {}   //   tyle
   
   
   
   let lineHeight = new lineHeightAttributor('lineHeight',
   'line-height', {
       scope: Parchment.Scope.INLINE,
       whitelist: ['1', '1.1','1.2','1.3','1.4','1.5','1.6','1.7','1.8','1.9','2','2.1','2.2','2.3','2.4','2.5','2.6','2.7','2.8','2.9','3']
   }); Quill.register({ "formats/lineHeight": lineHeight }, true);
   
   export default lineHeight;

// html 要配置class

// 
//     
//         v-for="(item, index) in lineHeight"
//     :key="index"
//     :value="item"
//     :selected="index === 0"
// >{{ item }}
// >
// 


// scss也要追加值进去不然不能回显内容
// 如：
// .ql-picker.ql-lineHeight .ql-picker-label[data-value='1']::before,
// .ql-picker.ql-lineHeight .ql-picker-item[data-value='1']::before {
//     content: "1.0";
// }

// vue中在这里加载
// import lineHeight from './lineHeight';

// mounted() {
//     Quill.register("formats/lineHeight", lineHeight, true);
// }

希望能帮到你！
