在IE和安卓系统中防止在初始页面加载时显示iFrame

<script>
    window.onload = function() {
        var isIE = /* 判断是否为IE浏览器的代码 */;
        var isAndroid = /* 判断是否为安卓系统的代码 */;

        if (isIE || isAndroid) {
            var iframe = document.getElementById('your-iframe-id');
            iframe.style.display = 'none';
        }
    }
</script>

<style>
    @media screen and (-ms-high-contrast: active), (-ms-high-contrast: none) {
        /* IE浏览器样式 */
        #your-iframe-id {
            display: none;
        }
    }

    @media screen and (max-width: 767px) {
        /* 安卓系统样式 */
        #your-iframe-id {
            display: none;
        }
    }
</style>
