I have polygons for various region and states in my application. Markers implement tooltip by taking the title attribute. On mouseover and mouseout over a polygon events can be fired. How do I create a tooltip that looks like the tooltip that is implemented for a marker.

Edit-1: Adding the code used to create the polygon and attach the handlers to show/hide tooltips.

function addPolygon(points) {
    var polygon = new google.maps.Polygon({
        paths: points,
        strokeColor: " #FFFFFF",
        strokeOpacity: 0.15,
        strokeWeight: 1.5,
        fillColor: "#99ff66",
        fillOpacity: 0.14
    });
    var tooltip = document.createElement('div');
    tooltip.innerHTML = "Alok";

    google.maps.event.addListener(polygon,'mouseover',function(){
        tooltip.style.visibility = 'visible';
    });
    google.maps.event.addListener(polygon,'mouseout',function(){
        tooltip.style.vi开发者_如何学运维sibility = 'hidden';
    });
    polygon.setMap(map);
}


There's actually a neat trick to work around this (strange) limitation in Google Maps. When moving your mouse over a data item, you can just add a tooltip to the map's <div>. It will be added at the location where your mouse pointer currently is - right over the item!

map.data.addListener('mouseover', mouseOverDataItem);
map.data.addListener('mouseout', mouseOutOfDataItem);

...

function mouseOverDataItem(mouseEvent) {
  const titleText = mouseEvent.feature.getProperty('propContainingTooltipText');

  if (titleText) {
    map.getDiv().setAttribute('title', titleText);
  }
}

function mouseOutOfDataItem(mouseEvent) {
  map.getDiv().removeAttribute('title');
}


I think you will have to do it yourself.In a page i have implemented i attached a mouse move event to the page so i can record the mouse position.Then when a polygon mouseover event occurs i display a custom div near the mouse position

Hope it helps


This code works for me: googleShape - is your polygon or circle or rectangle. titleText - message you need to post on hover of shapes.

google.maps.event.addListener(googleshape, 'mouseover', function() {
    this.map.getDiv().setAttribute('title', "`titleText`");
});
google.maps.event.addListener(googleshape, 'mouseout', function() {
    this.map.getDiv().removeAttribute('title');
});


You could try the following

//Add a listener for the click event
google.maps.event.addListener('click', showArrays);
infoWindow = new google.maps.InfoWindow;

then when the click event happens call the following function

function showArrays(event) {

  var contentString = 'Content here';

  // Replace the info window's content and position.
  infoWindow.setContent(contentString);
  infoWindow.setPosition(event.latLng);

  infoWindow.open(map);
}


A nice solution will be to use Google's built in InfoWindow as a tooltip/popup container. Then listen to mouseover and mouseout to show/hide the tooltip.

Notice that by using InfoWindow you can also put HTML markup as the content of the tooltip and not only plain text.

const mapHandler: google.maps.Map = ... // your code here
const polygon: google.maps.Polygon = ... // your colde here

const popUp = new google.maps.InfoWindow({
  content: "<span style='color:red'> SOME MESSAGE </span>" // red message
});

polygon.addListener("mouseover", (event) => {
  popUp.setPosition(event.latLng);
  popUp.open(mapHandler);
});

polygon.addListener("mouseout", (event) => {
  popUp.close()
});
