layui.open

layui.open里面有from表单。当点击input输入框弹出输入法，弹窗就会向下移动，导致弹窗下面的按钮溢出屏幕显示。

 // 监听窗口大小变化事件
$(window).on('resize', function(){
    var layero = $('.layui-layer').eq(index);
    adjustLayerPosition(layero);
});

function adjustLayerPosition(layero) {
        layero.css('top', '0');
 }
layer.open({
        type: 1,
        title: '新增',
        area: ['100%', '100%'],
        fixed: true,
        scrollbar:false,
        content: $('#addData'),
        btn: ['提交', '重置', '关闭'],
        yes: function () {
        },
        btn2: function () {
        },
        btn3: function () {
        },
	    success: function (layero, index) {
            adjustLayerPosition(layero);
        },
});
