Google 地图工具提示在全屏模式下不起作用

Question

我使用以下站点示例在悬停多边形上显示工具提示。

http://philmap.000space.com/gmap-api/poly-hov.html?i=1

在普通视图中，悬停时工具提示按预期工作。但在全屏模式下工具提示不显示工作。尝试用 z-index 修复，设置工具提示 div 相对位置但不起作用。

这是我的代码。提前致谢。

var map = new google.maps.Map(document.getElementById("mapD4"), {
        zoom: 14,
        center: {
            lat: parseFloat(6.890132), lng: parseFloat(79.87557)
        },
});

var data_layer_1 = new google.maps.Data({ map: map });

data_layer_1.loadGeoJson('https://raw.githubusercontent.com/Thanushkajayasinghe/D4Ward/main/Kirula.geojson');

data_layer_1.setStyle({
        strokeColor: '#8854d0',
        fillColor: '#8854d0',
        strokeOpacity: 1.0,
        strokeWeight: 1,
        fillOpacity: 0.7
});

//Tooltip data_layer_1 click
google.maps.event.addListener(data_layer_1, 'click', function (e) {

        var district = e.feature.j.CMC_Dis;
        var ward = e.feature.j.CMC_Ward;

        loadTooltip(district, ward);
});

function loadTooltip(district, ward) {
        $.ajax({
            url: LoadDisMapData,
            type: 'POST',
            data: { district: district, ward: ward },
            dataType: 'json',
            success: function (data) {

                tooltip.show("Ward: <span style='font-weight: bold'>" + ward + "</span><br/>\
                                Population: <span style='font-weight: bold'>" + data.sumPopulation.toString().replace(/,/g, "").replace(/\B(?=(\d{3})+(?!\d))/g, ",") + "</span><br/>\

问题是只有目标元素内的元素全屏显示。

所以你需要替换这一行

document.body.appendChild(tt);

和

document.getElementById('map_canvas').firstChild.appendChild(tt);
