如何在 map api v3 中创建一个可拖动的矩形，正如您在我的代码中看到的那样，我的矩形在标记中心上是可拖动的 onclick 我不会在单击所有矩形时拖动我的矩形以寻求帮助：
(function()
{
window.onload = function()
{
var path;
var counter = 0;
// Creating a map
var options =
{
zoom: 11,
center: new google.maps.LatLng(49.2541, -123.072),
mapTypeId: google.maps.MapTypeId.ROADMAP
};
map = new google.maps.Map(document.getElementById('mapDiv'), options);
};// end window.onload
})();// end anonymous function
