vue-quill-editor富文本使用

一、准备css文件

用于自定义富文本样式(我的放到了assets/css/quillEditor)

.ql-snow .ql-picker {
    height: none !important;
}
/* 行高 */
.ql-picker-options {
    line-height: 1.5;
}
/* 标题 */

    font-size: 20px;
}

.ql-snow .ql-picker.ql-size .ql-picker-label[data-value="22px"]::before,

二.在页面里使用

<template>
	<div class="editor-box" style="line-height: 0;">
		
        <el-upload
            action="#"
            class="upload-img"
            v-show="false"
            :http-request="httpRequest">
        el-upload>
 		<quill-editor
    		v-model="formObj.content"
    		ref="myQuillEditor"
    		:options="editorOption"
    		@blur="onEditorBlur($event)"
      		@focus="onEditorFocus($event)"
      		@change="onEditorChange($event)">
    	quill-editor>
	div>
