Answer 1

看文档：vue-print-nb

export default {
    data() {
        return {
           printLoading: true,
            printObj: {
              id: "printMe",
              preview: true,
              previewTitle: 'print Title', // The title of the preview window. The default is 打印预览
              popTitle: 'good print',
              extraCss: "https://cdn.bootcdn.net/ajax/libs/animate.css/4.1.1/animate.compat.css, https://cdn.bootcdn.net/ajax/libs/hover.css/2.3.1/css/hover-min.css",
              extraHead: '<meta http-equiv="Content-Language"content="zh-cn"/>',
              previewBeforeOpenCallback (vue) {
                console.log('正在加载预览窗口')
              },
              previewOpenCallback (vue) {
                console.log('已经加载完预览窗口')
              },
              beforeOpenCallback (vue) {
                vue.printLoading = true
                console.log('打开之前')
              },
              openCallback (vue) {
                vue.printLoading = false
                console.log('执行了打印')
              },
              closeCallback (vue) {
                console.log('关闭了打印工具')
              }
            }
        };
    }
}
