vue實現(xiàn)導(dǎo)出Word文件(數(shù)據(jù)流方式)
更新時間：2022年06月01日 09:29:10 作者：清虛桂意
這篇文章主要介紹了vue實現(xiàn)導(dǎo)出Word文件(數(shù)據(jù)流方式)，具有很好的參考價值，希望對大家有所幫助。如有錯誤或未考慮完全的地方，望不吝賜教
jquery.wordexport.js，通過該插件可以導(dǎo)出文本和圖片，圖片通過canvas的形式繪制，文本則需要依賴FileSaver.js插件。
FileSaver.js插件則主要通過H5的文件操作新特性new Blob()和new FileReader()來實現(xiàn)文本的導(dǎo)出。
第一步：安裝依賴：jquery 和file-saver
npm install jquery file-saver --save
第二步：新增jquery.wordexport.js
在src下的assets中新增js文件夾，新增jquery.wordexport.js文件
// 導(dǎo)入js文件

</div>
</div>
</template>import $ from 'jquery'
require('@/assets/js/jquery.wordexport')

模板參數(shù)名需與字段一致，普通字段：{字段名}，圖片字段：{%字段名}
