   API.diseaseExportExcel().then(result=>{
        let iframe = document.createElement('iframe')
        //console.log(iframe)
        iframe.style.display = 'none'
        iframe.src = '/yxcAdmin/disease/export/excel'
        iframe.onload = function () {
            document.body.removeChild(iframe)
        }
        document.body.appendChild(iframe)
    },function (err) {
        this.$message.error({
            showClose: true,
            message: err.message.toString(),
            duration: 2000
        });
    }).catch()
}
