    import pdf from 'vue-pdf'

    export default {
        name: "detail",
        components: {
            pdf
        },
        data() {
            return {
                loading: true,   // 显示加载效果         
                src: '',
                numPages: undefined, // 总页数
                curPageNum: 0, //当前页
            }
        },
        methods: {
            pageLoaded(e) {
                this.curPageNum = e;
                if (this.curPageNum == this.numPages) { //加载完最后一页
                    this.loading = false;
                }
            },
        },
        mounted() {
            let that = this,
                 url = '***';
            that.$refs.detail.scrollIntoView(true);
            that.src = pdf.createLoadingTask(url); // url是pdf文件的全路径
            that.src.promise.then(pdf => {
                that.numPages = pdf.numPages;
            });
        },
    }
