Question

我正在编写地图，并根据GeoJSON文件在其上放置标记。我的标记在地图上很好地显示了良好的坐标，现在我想实现一个侧面菜单。我创建了一个带有复选框的sidemenu，我希望只有在单击相关复选框时才会显示标记。

我的代码中有两部分，第一部分是import，div和sidemenu（nd的一部分），第二部分是显示地图和标记所需的所有OpenLayers代码（在标记中）。

我该怎么做？我找到了这段代码：

function verifyCheckBoxes(source){
    document.getElementById('button-checkbox-'+source).checked = false;
}

但是如何选择复选框信息才能在我的标记中使用这些信息？

我有这段代码：

公平地说，这类问题有很多例子。我已经尝试了类似的东西而不是矢量图层我正在添加/删除底图

$('#customCheck1').on('change', function() {
  var isChecked = $(this).is(':checked');
  if (isChecked) {
    map.addLayer(osmBasic)
  } else {
    map.removeLayer(osmBasic);
  }
})

这是小提琴
