javascript - 从 jQuery/Js 添加类到谷歌标记

Question

如何为标记在不同位置的每个标记添加一个 class 到 google 标记中。这样我就可以在点击这些标记时执行 .fadeIn() 和 .fadeOut() 功能。

我不认为添加它会起作用。

var NewYork = new google.maps.Marker({
  position: mapOptions.center,
  map: map,
  icon: img
});
marker.addListener('click', changeContent);
}

function changeContent() {
    $("#klk-map-content-1").fadeOut(fast, function(){
        $("#klk-map-content-2").fadeIn("slow");
    });
}

左侧也是每个标记的内容。因此，当用户选择其中一个标记时，内容将发生变化。

好的，我就是这样解决的，你的方向很好。

先猜一猜:

var NewYork = new google.maps.Marker({
position: mapOptions.center,
map: map,
icon: img
});
marker.addListener('click', changeContent);
}

function changeContent() {
$("#klk-map-content-1").fadeOut(fast, function(){
    $("#klk-map-content-2").fadeIn("slow");
});
}

您的代码中没有名为 marker 的任何内容，因此如果您真的想向 New York 标记添加一个事件监听器，您应该这样写:

NewYork.addListener('click', changeContent);

并在 fadeout() 中将 fast 写为“fast”

这是你的例子恢复工作:
