Question

我创建了两个CustomControls，但是第一个按钮上的第一个设置重复。我确定这个错误是新手。我能够找到的大多数示例只显示一个按钮，或者他们正在向标记添加控件。任何指导都将非常感谢！

您的代码中有拼写错误。您正在创建类CustomControl的两个副本，您从不创建CustomControl1类。

正在运行的代码段（您还有一个语法错误）：

function CustomControl(controlDiv, map, deviceID) {
  // Set CSS for the control border
  var controlUI = document.createElement('div');
  //controlUI.style.backgroundColor = '#f00c0c';
  controlUI.style.backgroundColor = '#ffffff';
  controlUI.style.borderStyle = 'solid';
  controlUI.style.borderWidth = '1px';
  controlUI.style.borderColor = '#ccc';
  controlUI.style.borderRadius = "23px";
  controlUI.style.height = '33px';
  controlUI.style.marginTop = '5px';
  controlUI.style.marginLeft = '-6px';
  controlUI.style.paddingTop = '1px';
  controlUI.style.cursor = 'pointer';
  controlUI.style.textAlign = 'center';
  controlUI.title = 'Click to change settings';
  controlDiv.appendChild(controlUI);

  // Set CSS for the control interior
  var controlText = document.createElement('div');
  controlText.style.fontFamily = 'sans-serif';
  controlText.style.fontSize = '10px';
  controlText.style.paddingLeft = '4px';
  controlText.style.paddingRight = '8px';
  controlText.style.marginTop = '10px';
  controlText.innerHTML = 'Settings';
  controlUI.appendChild(controlText);

  // Setup the click event listeners
  google.maps.event.addDomListener(controlUI, 'click', function() {
    url = "http://excite.bounceme.net/profile.html";
    window.location = url;
  });
}

function CustomControl1(controlDiv, map, deviceID) {
  // Set CSS for the control border
  var controlUI1 = document.createElement('empty');
  //controlUI1.style.backgroundColor = '#f00c0c';
  controlUI1.style.backgroundColor = '#ffffff';
  controlUI1.style.borderStyle = 'solid';
  controlUI1.style.borderWidth = '1px';
  controlUI1.style.borderColor = '#ccc';
  controlUI1.style.borderRadius = "23px";
  controlUI1.style.height = '33px';
  controlUI1.style.marginTop = '5px';
  controlUI1.style.marginLeft = '-6px';
  controlUI1.style.paddingTop = '1px';
  controlUI1.style.cursor = 'pointer';
  controlUI1.style.textAlign = 'center';
  controlUI1.title = 'Click to plot course';
  controlDiv.appendChild(controlUI1);

  // Set CSS for the control interior
  var controlText1 = document.createElement('empty');
  controlText1.style.fontFamily = 'sans-serif';
  controlText1.style.fontSize = '10px';
  controlText1.style.paddingLeft = '4px';
  controlText1.style.paddingRight = '8px';
  controlText1.style.marginTop = '10px';
  controlText1.innerHTML = 'Plot Route';
  controlUI1.appendChild(controlText1);

  // Setup the click event listeners
  google.maps.event.addDomListener(controlUI1, 'click', function() {
    url = "http://excite.bounceme.net/settings.html";
    window.location = url;
  });
}

function start() {
  var map;
  var deviceID = "A";
  map = new google.maps.Map(document.getElementById('map'), {
    center: {
      lat: 39.833,
      lng: -98.585
    },
    zoom: 12
  });
  var customControlDiv = document.createElement('div');
  var customControl = new CustomControl(customControlDiv, map, deviceID);
  customControlDiv.index = 1;
  map.controls[google.maps.ControlPosition.TOP_RIGHT].push(customControlDiv);
  var customControlDiv1 = document.createElement('div');
  var customControl1 = new CustomControl1(customControlDiv1, map, deviceID);
  customControlDiv1.index = 2;
  map.controls[google.maps.ControlPosition.RIGHT_TOP].push(customControlDiv1);
}
google.maps.event.addDomListener(window, "load", start);
