vue实现打印功能

作者: 莫伊剑客 | 来源:发表于2022-01-24 16:03 被阅读0次

    打印功能可以自己使用原生js(window.print())实现,其次就是使用插件,介绍一个打印插件

    vue-print-nb:这个插件使用起来还是很便捷的,用法如下
    1、安装

    // vue2.0
    npm install vue-print-nb --save
    // vue3.0
    npm install vue3-print-nb --save
    

    请根据自己的需求安装版本

    2、配置
    vue2.0

    // 全局配置
    import Print from 'vue-print-nb'
    Vue.use(Print);
    
    // 仅使用页面配置
    import print from 'vue-print-nb'
    directives: {
        print   
    }
    

    vue3.0

    // 全局配置
    import print from 'vue3-print-nb'
    const app = createApp(App)
    app.use(print)
    
    // 仅使用页面配置
    import print from 'vue3-print-nb'
    directives: {
        print   
    }
    

    3、具体使用方法:(1)直接绑定id方法 (2)绑定对象方法

    <!--直接绑定id方法-->
    <div id='box'>
       <p>打印内容</p>
       <p>打印内容1111</p>
    </div>
    <div v-print="'#box'">打印</div>
    
    <!--直接绑定对象方法-->
    <div id='box'>
       <p>打印内容</p>
       <p>打印内容1111</p>
    </div>
    <div v-print='printObj'>打印</div>
    
    export default{
       data(){
          return {
             printObj:{
                id:'box',
                beforeOpenCallback (vue) {
                    console.log('打开之前')
                },
                openCallback (vue) {
                    console.log('执行了打印')
                },
                closeCallback (vue) {
                    console.log('关闭了打印工具')
                }
                //其他配置项,
             }
          }
       }
    }
