問題描述：編輯器的文字內容變更後，編輯器自動獲取焦點，滾動條定位到編輯期處 解決思路：文字內容變更後，先禁編輯器，待元件渲染完成後，丟掉編輯期的焦點，再取消禁用，完美解決問題

const editor = this.$refs.editor;
this.Quill = new Quill(editor, this.options);

//禁用編輯器，防止頁面自動滾動到編輯器位置
this.Quill.enable(false);
// 編輯器繫結內容，如修改的時候原有的內容
this.Quill.pasteHTML(this.currentValue);
this.$nextTick(function() {
//丟掉編輯器焦點並重新啟用編輯器
this.Quill.blur();
this.Quill.enable(true);
});

完整程式碼如下：

<template>
<div>
<el-upload :action="uploadUrl" :on-success="handleUploadSuccess" :on-error="handleUploadError" name="file"
:show-file-list="false" :headers="headers" style="display: none" ref="upload" v-if="this.uploadUrl">
</el-upload>
<div class="editor" ref="editor"
 
 :style="styles"></div>
</div>
