vue 导出 excel ，并兼容ie

多次使用 创建公共方法

import axios from 'axios'
// 导出Excel公用方法
export function exportMethod(data) {
    axios({
        method: data.method,
        url: `${data.url}${data.params ? '?' + data.params : ''}`,
        responseType: 'blob'
    }).then((res) => {
        let blob = new Blob([res.data], {type: 'application/vnd.ms-excel'})
        
        const link = document.createElement('a')
        var explorer = window.navigator.userAgent ;//获取浏览器；
        console.log(explorer,11111)
            //ie 
            if (!!window.ActiveXObject || "ActiveXObject" in window || navigator.userAgent.indexOf("Edge") > -1) {
                let fileName = "PR管理模板"+'.xls'
                navigator.msSaveBlob(blob,fileName)
            }else{
        link.style.display = 'none'
        link.href = URL.createObjectURL(blob)
        // link.download = res.headers['content-disposition'] //下载后文件名
        link.download = data.fileName //下载的文件名
        document.body.appendChild(link)
        link.click()
        document.body.removeChild(link)
        }
        

    }).catch(error => {
        this.$Notice.error({
            title: '错误',
            desc: '网络连接错误'
        })
        console.log(error)
    })
}

使用该方法的页面中引入

import { exportMethod } from '@/utils/untils'

    prexportxls() {
        let myObj = {
                        method: 'get',
                        url: 'api/woas/pr/prExport',
                        fileName: 'PR管理模板',
                        // params: `startDate=${changeDate(this.dateValue[0])}&endDate=${changeDate(this.dateValue[1])}`
                    }
                    exportMethod(myObj)
    }
