移动端网页解决input框中即输入即计算的问题

if (/Android/gi.test(navigator.userAgent)) {
    const innerHeight = window.innerHeight;
    window.addEventListener('resize', () => {
        const newInnerHeight = window.innerHeight;
    if (innerHeight > newInnerHeight) {
        $(".later_num").html(formatNum($("#reChargeM").val()))
    } else {
        $(".later_num").html(formatNum($("#reChargeM").val()))
    }
});
} else {
    window.addEventListener('focusin', () => {
        $(".later_num").html(formatNum($("#reChargeM").val()))
    });
    window.addEventListener('focusout', () => {
        $(".later_num").html(formatNum($("#reChargeM").val()))
    });
}
