Javascript 如何避免Android键盘在我点击输入后自动关闭？

直到最近几年，我的PWA一直运转良好。现在，键盘似乎出现了一个新问题，因为我根本无法键入任何内容

在我看来，我的bug与另一个众所周知的问题有关：“当我们打开键盘时，Web应用程序的大小会违背我们的意愿。”（我想知道Twitter有什么作用，因为当我点击输入时它不会调整大小）

这是我的一些代码。我写下了他们试图阻止应用程序调整大小：

HTML:

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no, shrink-to-fit=no">

window.onresize = function() {
    resizeScreen();
};

function resizeScreen() {
    let scaleVal = window.innerHeight / 600;
    if (window.innerHeight < 514) {
        if (externalContainer === null) {
            let bodyTmp = document.body;
            let divTmp = document.createElement("div");
            divTmp.id = 'externalContainer';
            bodyTmp.insertBefore(divTmp, bodyTmp.firstChild);
        }
        externalContainer = document.getElementById('externalContainer');
        let sContainer = document.getElementById('superContainer');
        externalContainer.append(sContainer);
        externalContainer.style.height = `${window.innerHeight}px`;
        sContainer.style.transformOrigin = "50% 0% 0px";

        setTimeout(function() {
            sContainer.style.transform = `scale(${scaleVal})`;
            setTimeout(function() {
                let cHeight = (1 + scaleVal) * window.innerHeight;
                if (cHeight < 514)
                    cHeight = 514;
                sContainer.style.height = `${cHeight}px`;
            }, 100);
        }, 100);
    } else {
        let sContainer = document.getElementById('superContainer');
        sContainer.style.height = `${window.innerHeight}px`;
        sContainer.style.transformOrigin = "50% 0% 0px";

        setTimeout(function() {
            sContainer.style.transform = `scale(${scaleVal})`;
        }, 100);

        setTimeout(function() {
            if (cmbSpeechType.getBoundingClientRect().width > window.outerWidth)
                sContainer.style.transform = `scale(${scaleVal - (scaleVal - cmbSpeechType.getBoundingClientRect().width / window.outerWidth)})`;
        }, 100);
    }
}

你知道如何解决这个奇怪的问题吗

p.S.：

<meta name="viewport" content="width=device-width, initial-scale=1.0, maximum-scale=1.0, user-scalable=no, shrink-to-fit=no">

window.onresize = function() {
    resizeScreen();
};

function resizeScreen() {
    let scaleVal = window.innerHeight / 600;
    if (window.innerHeight < 514) {
        if (externalContainer === null) {
            let bodyTmp = document.body;
            let divTmp = document.createElement("div");
            divTmp.id = 'externalContainer';
            bodyTmp.insertBefore(divTmp, bodyTmp.firstChild);
        }
        externalContainer = document.getElementById('externalContainer');
        let sContainer = document.getElementById('superContainer');
        externalContainer.append(sContainer);
        externalContainer.style.height = `${window.innerHeight}px`;
        sContainer.style.transformOrigin = "50% 0% 0px";

        setTimeout(function() {
            sContainer.style.transform = `scale(${scaleVal})`;
            setTimeout(function() {
                let cHeight = (1 + scaleVal) * window.innerHeight;
                if (cHeight < 514)
                    cHeight = 514;
                sContainer.style.height = `${cHeight}px`;
            }, 100);
        }, 100);
    } else {
        let sContainer = document.getElementById('superContainer');
        sContainer.style.height = `${window.innerHeight}px`;
        sContainer.style.transformOrigin = "50% 0% 0px";

        setTimeout(function() {
            sContainer.style.transform = `scale(${scaleVal})`;
        }, 100);

        setTimeout(function() {
            if (cmbSpeechType.getBoundingClientRect().width > window.outerWidth)
                sContainer.style.transform = `scale(${scaleVal - (scaleVal - cmbSpeechType.getBoundingClientRect().width / window.outerWidth)})`;
        }, 100);
    }
}

这是一个特定于Android的bug，因为在iOS和Windows10上，PWA工作正常。毕竟，视图没有调整大小。

我通过执行以下操作修复了它：

function androidOrIOS() {
    const userAgent = navigator.userAgent;
    if(/android/i.test(userAgent)){
        return 'android';
    }
    if(/iPad|iPhone|iPod/i.test(userAgent)){
        return 'ios';
    }
}

var os = androidOrIOS();

//Only resize if it´s Android
if (os !== "Android") {
    window.onresize = function() {
        resizeScreen();
    };
}


//Change the location of the body based on the location that I "need".
if (os === "Android") {
    txtSpeaker.addEventListener("onfocus", function() {
        let y = document.getElementById("playControl").getBoundingClientRect().y;
        document.body.marginTop = `-${y}px`;
    });
    
    txtSpeaker.addEventListener("onblur", function() {
        document.body.marginTop = '0px';
    });
}
