Google Maps API InfoWindow應該默認打開

Question

我嘗試Google Maps API並遇到小問題。看下面的這個例子。我想在進入網站時打開Infobox（不像谷歌的這個例子中，它是由點擊事件觸發並觸發的）。如何管理這個？也許這是一個初學者的問題的谷歌地圖API的親^^

Answer 1

只需添加infowindow.open(map,marker);您initialize()函數的末尾：

function initialize() { 
    var myLatlng = new google.maps.LatLng(-25.363882,131.044922); 
    var myOptions = { 
     zoom: 4, 
     center: myLatlng, 
     mapTypeId: google.maps.MapTypeId.ROADMAP 
    } 

    var map = new google.maps.Map(document.getElementById("map_canvas"), myOptions); 

    var contentString = '<div id="content">'+ 
     '<div id="siteNotice">'+ 
     '</div>'+ 
     '<h1 id="firstHeading" class="firstHeading">Uluru</h1>'+ 
     '<div id="bodyContent">'+ 
     '<p><b>Uluru</b>, also referred to as <b>Ayers Rock</b>, is a large ' + 
     'sandstone rock formation in the southern part of the '+ 
     'Northern Territory, central Australia. It lies 335&#160;km (208&#160;mi) '+ 
     'south west of the nearest large town, Alice Springs; 450&#160;km '+ 
     '(280&#160;mi) by road. Kata Tjuta and Uluru are the two major '+ 
     'features of the Uluru - Kata Tjuta National Park. Uluru is '+ 
     'sacred to the Pitjantjatjara and Yankunytjatjara, the '+ 
     'Aboriginal people of the area. It has many springs, waterholes, '+ 
     'rock caves and ancient paintings. Uluru is listed as a World '+ 
     'Heritage Site.</p>'+ 
     '<p>Attribution: Uluru, <a href="http://en.wikipedia.org/w/index.php?title=Uluru&oldid=297882194">'+ 
     'http://en.wikipedia.org/w/index.php?title=Uluru</a> '+ 
     '(last visited June 22, 2009).</p>'+ 
     '</div>'+ 
     '</div>'; 

    var infowindow = new google.maps.InfoWindow({ 
     content: contentString 
    }); 

    var marker = new google.maps.Marker({ 
     position: myLatlng, 
     map: map, 
     title: 'Uluru (Ayers Rock)' 
    }); 
    google.maps.event.addListener(marker, 'click', function() { 
     infowindow.open(map,marker); 
    }); 

    infowindow.open(map,marker); 
    }
