Google maps api 3 打开错误的信息窗口谷歌地图v3

可能重复：

function markNow(){   

google.maps.event.addListener(map, "click", function(event) 
{
    if (doMark == true){
    alert("Marker 1 Chosen");
    marker = new google.maps.Marker({
    position: event.latLng,
    map: map,
    icon: 'Imagens/Oficina.png',
    });
    }
    if (doMark2 == true){
    alert("Marker 2 Chosen");
    marker = new google.maps.Marker({ 
    position: event.latLng,
    map: map,
    icon: 'Imagens/Lojas.png',
    });
    }
    //if (doMark ==1)
    google.maps.event.addListener(marker, "click", function() 
    {
        infowindow.open(map, this);

    }


    );

}
);
var html = "<table>" +
   "<tr><td>Nome:</td> <td><input type='text' id='name'/> </td> </tr>" +
   "<tr><td>Ensdereco:</td> <td><input type='text' id='address'/></td> </tr>" +
   "<tr><td>Tipo:</td> <td><select id='type'>" +
   "<option value='oficina' SELECTED>oficina</option>" +
   "<option value='restaurante'>restaurante</option>" +
   "</select> </td></tr>" +
   "<tr><td></td><td><input type='button' value='Salvar' onclick='saveData()'/>        </td></tr>";

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

在我的项目中，您可以在地图上创建标记，然后打开一个信息窗口以放置一些信息并保存到数据库中，但是当您创建一个标记，然后再创建另一个标记时，如果单击第一个标记，则会打开第二个标记的信息窗口

function markNow(){   

google.maps.event.addListener(map, "click", function(event) 
{
    if (doMark == true){
    alert("Marker 1 Chosen");
    marker = new google.maps.Marker({
    position: event.latLng,
    map: map,
    icon: 'Imagens/Oficina.png',
    });
    }
    if (doMark2 == true){
    alert("Marker 2 Chosen");
    marker = new google.maps.Marker({ 
    position: event.latLng,
    map: map,
    icon: 'Imagens/Lojas.png',
    });
    }
    //if (doMark ==1)
    google.maps.event.addListener(marker, "click", function() 
    {
        infowindow.open(map, this);

    }


    );

}
);
var html = "<table>" +
   "<tr><td>Nome:</td> <td><input type='text' id='name'/> </td> </tr>" +
   "<tr><td>Ensdereco:</td> <td><input type='text' id='address'/></td> </tr>" +
   "<tr><td>Tipo:</td> <td><select id='type'>" +
   "<option value='oficina' SELECTED>oficina</option>" +
   "<option value='restaurante'>restaurante</option>" +
   "</select> </td></tr>" +
   "<tr><td></td><td><input type='button' value='Salvar' onclick='saveData()'/>        </td></tr>";

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

有什么不对劲？这是我的代码： 这是一个简化的代码，用于完整的代码

function markNow(){   

google.maps.event.addListener(map, "click", function(event) 
{
    if (doMark == true){
    alert("Marker 1 Chosen");
    marker = new google.maps.Marker({
    position: event.latLng,
    map: map,
    icon: 'Imagens/Oficina.png',
    });
    }
    if (doMark2 == true){
    alert("Marker 2 Chosen");
    marker = new google.maps.Marker({ 
    position: event.latLng,
    map: map,
    icon: 'Imagens/Lojas.png',
    });
    }
    //if (doMark ==1)
    google.maps.event.addListener(marker, "click", function() 
    {
        infowindow.open(map, this);

    }


    );

}
);
var html = "<table>" +
   "<tr><td>Nome:</td> <td><input type='text' id='name'/> </td> </tr>" +
   "<tr><td>Ensdereco:</td> <td><input type='text' id='address'/></td> </tr>" +

   "<tr><td></td><td><input type='button' value='Salvar' onclick='saveData()'/>        </td></tr>";

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

实际上，函数markNow-

 marker = new google.maps.Marker({
                     position: event.latLng, 
                     map: map, icon: 'Imagens/Oficina.png',
                     shadow: 'Imagens/Oficinasombra.png',
                     draggable : true,
                     animation: google.maps.Animation.DROP});
google.maps.event.addListener(marker,'click',showWindow);

function markNow(){   

google.maps.event.addListener(map, "click", function(event) 
{
    if (doMark == true){
    alert("Marker 1 Chosen");
    marker = new google.maps.Marker({
    position: event.latLng,
    map: map,
    icon: 'Imagens/Oficina.png',
    });
    }
    if (doMark2 == true){
    alert("Marker 2 Chosen");
    marker = new google.maps.Marker({ 
    position: event.latLng,
    map: map,
    icon: 'Imagens/Lojas.png',
    });
    }
    //if (doMark ==1)
    google.maps.event.addListener(marker, "click", function() 
    {
        infowindow.open(map, this);

    }


    );

}
);
var html = "<table>" +
   "<tr><td>Nome:</td> <td><input type='text' id='name'/> </td> </tr>" +
   "<tr><td>Ensdereco:</td> <td><input type='text' id='address'/></td> </tr>" +
   "<tr><td>Tipo:</td> <td><select id='type'>" +
   "<option value='oficina' SELECTED>oficina</option>" +
   "<option value='restaurante'>restaurante</option>" +
   "</select> </td></tr>" +
   "<tr><td></td><td><input type='button' value='Salvar' onclick='saveData()'/>        </td></tr>";

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

然后-

function showWindow(event) 
{
infoWindow.setContent(html); 
infoWindow.open(map,marker); 
} 

function markNow(){   

google.maps.event.addListener(map, "click", function(event) 
{
    if (doMark == true){
    alert("Marker 1 Chosen");
    marker = new google.maps.Marker({
    position: event.latLng,
    map: map,
    icon: 'Imagens/Oficina.png',
    });
    }
    if (doMark2 == true){
    alert("Marker 2 Chosen");
    marker = new google.maps.Marker({ 
    position: event.latLng,
    map: map,
    icon: 'Imagens/Lojas.png',
    });
    }
    //if (doMark ==1)
    google.maps.event.addListener(marker, "click", function() 
    {
        infowindow.open(map, this);

    }


    );

}
);
var html = "<table>" +
   "<tr><td>Nome:</td> <td><input type='text' id='name'/> </td> </tr>" +

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

实际上，函数markNow中的每个标记都应该附加一个单独的侦听器-

 marker = new google.maps.Marker({
                     position: event.latLng, 
                     map: map, icon: 'Imagens/Oficina.png',
                     shadow: 'Imagens/Oficinasombra.png',
                     draggable : true,
                     animation: google.maps.Animation.DROP});
google.maps.event.addListener(marker,'click',showWindow);

function markNow(){   

google.maps.event.addListener(map, "click", function(event) 
{
    if (doMark == true){
    alert("Marker 1 Chosen");
    marker = new google.maps.Marker({
    position: event.latLng,
    map: map,
    icon: 'Imagens/Oficina.png',
    });
    }
    if (doMark2 == true){
    alert("Marker 2 Chosen");
    marker = new google.maps.Marker({ 
    position: event.latLng,
    map: map,
    icon: 'Imagens/Lojas.png',
    });
    }
    //if (doMark ==1)
    google.maps.event.addListener(marker, "click", function() 
    {
        infowindow.open(map, this);

    }


    );

}
);
var html = "<table>" +
   "<tr><td>Nome:</td> <td><input type='text' id='name'/> </td> </tr>" +
   "<tr><td>Ensdereco:</td> <td><input type='text' id='address'/></td> </tr>" +
   "<tr><td>Tipo:</td> <td><select id='type'>" +
   "<option value='oficina' SELECTED>oficina</option>" +
   "<option value='restaurante'>restaurante</option>" +
   "</select> </td></tr>" +
   "<tr><td></td><td><input type='button' value='Salvar' onclick='saveData()'/>        </td></tr>";

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

然后-

function showWindow(event) 
{
infoWindow.setContent(html); 
infoWindow.open(map,marker); 
} 

function markNow(){   

google.maps.event.addListener(map, "click", function(event) 
{
    if (doMark == true){
    alert("Marker 1 Chosen");
    marker = new google.maps.Marker({
    position: event.latLng,
    map: map,
    icon: 'Imagens/Oficina.png',
    });
    }
    if (doMark2 == true){
    alert("Marker 2 Chosen");
    marker = new google.maps.Marker({ 
    position: event.latLng,
    map: map,
    icon: 'Imagens/Lojas.png',
    });
    }
    //if (doMark ==1)
    google.maps.event.addListener(marker, "click", function() 
    {
        infowindow.open(map, this);

    }


    );

}
);
var html = "<table>" +
   "<tr><td>Nome:</td> <td><input type='text' id='name'/> </td> </tr>" +
   "<tr><td>Ensdereco:</td> <td><input type='text' id='address'/></td> </tr>" +
   "<tr><td>Tipo:</td> <td><select id='type'>" +
   "<option value='oficina' SELECTED>oficina</option>" +
   "<option value='restaurante'>restaurante</option>" +
   "</select> </td></tr>" +
   "<tr><td></td><td><input type='button' value='Salvar' onclick='saveData()'/>        </td></tr>";

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

通过调用infowindow.openmap，marker将调用您看到的最后一个标记。您需要识别单击的标记以将infowindow附加到此标记

function markNow(){   

google.maps.event.addListener(map, "click", function(event) 
{
    if (doMark == true){
    alert("Marker 1 Chosen");
    marker = new google.maps.Marker({
    position: event.latLng,
    map: map,
    icon: 'Imagens/Oficina.png',
    });
    }
    if (doMark2 == true){
    alert("Marker 2 Chosen");
    marker = new google.maps.Marker({ 
    position: event.latLng,
    map: map,
    icon: 'Imagens/Lojas.png',
    });
    }
    //if (doMark ==1)
    google.maps.event.addListener(marker, "click", function() 
    {
        infowindow.open(map, this);

    }


    );

}
);
var html = "<table>" +
   "<tr><td>Nome:</td> <td><input type='text' id='name'/> </td> </tr>" +
   "<tr><td>Ensdereco:</td> <td><input type='text' id='address'/></td> </tr>" +
   "<tr><td>Tipo:</td> <td><select id='type'>" +
   "<option value='oficina' SELECTED>oficina</option>" +
   "<option value='restaurante'>restaurante</option>" +
   "</select> </td></tr>" +
   "<tr><td></td><td><input type='button' value='Salvar' onclick='saveData()'/>        </td></tr>";

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

更改infowindow.openmap，标记；要访问infowindow.openmap，请执行以下操作：

function markNow(){   

google.maps.event.addListener(map, "click", function(event) 
{
    if (doMark == true){
    alert("Marker 1 Chosen");
    marker = new google.maps.Marker({
    position: event.latLng,
    map: map,
    icon: 'Imagens/Oficina.png',
    });
    }
    if (doMark2 == true){
    alert("Marker 2 Chosen");
    marker = new google.maps.Marker({ 
    position: event.latLng,
    map: map,
    icon: 'Imagens/Lojas.png',
    });
    }
    //if (doMark ==1)
    google.maps.event.addListener(marker, "click", function() 
    {
        infowindow.open(map, this);

    }


    );

}
);
var html = "<table>" +
   "<tr><td>Nome:</td> <td><input type='text' id='name'/> </td> </tr>" +
   "<tr><td>Ensdereco:</td> <td><input type='text' id='address'/></td> </tr>" +

希望这能解决你的问题。让我知道如果你有一个问题，我试图把这个代码在我的项目，在markNow；和函数外，但不起作用=/。您能用所做的更改显示代码吗？可能有一个错误，我更新了我的代码，检查=，我不知道为什么不工作。标记没有打开，如果你想知道你有什么错误，你可以检查我在ask上的链接上的完整代码。在showWindow中实际上无法访问您的var html。因此，您应该在全局范围内声明var html以及var标记；和var信息窗口；然后像你那样分配文本。看看这个改变是否能解决问题。希望这能解决你的问题。让我知道如果你有一个问题，我试图把这个代码在我的项目，在markNow；和函数外，但不起作用=/。您能用所做的更改显示代码吗？可能有一个错误，我更新了我的代码，检查=，我不知道为什么不工作。标记没有打开，如果你想知道你有什么错误，你可以检查我在ask上的链接上的完整代码。在showWindow中实际上无法访问您的var html。因此，您应该在全局范围内声明var html以及var标记；和var信息窗口；然后像你那样分配文本。看看这个变化是否解决了问题。
