})
onMounted(() => {

})
//默认选中近七天
function getNowTime() {
    // let that=this
    const end = new Date();
    const start = new Date();
    start.setTime(start.getTime() - 3600 * 1000 * 24 * 7);
    // console.log([start, end])
    form.startTime= formatDate(start);

function formatDate(date) {
    var myyear = date.getFullYear();
    var mymonth = date.getMonth() + 1;
    var myweekday = date.getDate();
    var h = date.getHours();
    if (mymonth < 10) {
    mymonth = "0" + mymonth;
    }
    if (myweekday < 10) {
    myweekday = "0" + myweekday;
    }
    h = h < 10 ? "0" + h : h;
    var m = date.getMinutes();
    m = m < 10 ? "0" + m : m;
    var s = date.getSeconds();
    s = s < 10 ? "0" + s : s;
    return (
    myyear + "-" + mymonth + "-" + myweekday + " " + h + ":" + m + ":" + s
    );
