实现一个 vue-quill-editor 插件
官网文档
一般的使用参考文档的是使用方法，参考如下
<template>
<div class="example">
<quill-editor
class="editor"
ref="myTextEditor"
:value="content"
:options="editorOption"
@change="onEditorChange"
@blur="onEditorBlur($event)"
@focus="onEditorFocus($event)"
@ready="onEditorReady($event)"
/>
<div class="output code">
<code class="hljs" v-html="contentCode"></code>
</div>
<div class="output ql-snow">
<div class="ql-editor" v-html="content"></div>
</div>
</div>
</template>

</style>实现一个粘贴图片的功能
刚开始接触 vue 的开发，就接了个需求是实现富文本粘贴功能。
直接上代码。
// 输出一个模块
export class ImagePaste {
//quill 和 options->方便定义一些配置
constructor(quill, options = {}) {
// save the quill
this.quill = quill;
//绑定事件
this.handlePaste = this.handlePaste.bind(this);
// 坚挺粘贴事件
this.quill.root.addEventListener("paste", this.handlePaste, false);
}
//处理粘贴事件
//还需要根据复制的数据类型作一下判断
// 读取到剪贴板中的数据 具体的参考使用 可以看下MDN的文档 基本主流的浏览器都支持了
handlePaste(e) {
if (
e.clipboardData &&
e.clipboardData.items &&
e.clipboardData.items.length
) {
const clipboardData = e.clipboardData;
const items = clipboardData.items;
const item = items[0];
if (item && item.kind === "file" && item.type.match(/^image\//i)) {
e.preventDefault()
this.file = item.getAsFile();
this.toBase64();
}
}
}
toBase64() {
// 转换成base64 也可以压缩图片进行上传
const reader = new FileReader();
reader.onload = e => {
this.insertImg(e.target.result);
};
reader.readAsDataURL(this.file);
}
insertImg(baseUrl) {
// 插入文本中
const currentIndex = this.quill.getSelection().index || 0;
this.quill.insertEmbed(currentIndex, "image", baseUrl);
this.quill.setSelection(currentIndex + 1);
this.quill.update();
// 更新光标的位置
}
}使用
import { quillEditor, Quill } from "vue-quill-editor";
import ImagePaste;
Quill.register("modules/ImagePaste", ImagePaste);
import "quill/dist/quill.core.css";
import "quill/dist/quill.snow.css";
import "quill/dist/quill.bubble.css";
