Question

我正在进行maplayer切换功能，但是当我切换图层时，未选中所选功能。我是否知道如何在openlayer 3中取消选择一项功能。

$("#show-field-map").click(function(event) {
    map.removeLayer(subbasinJsonp);
    map.addLayer(fieldJsonp);
    $('#show-subbasin-map').attr("disabled", false);
    $('#show-field-map').attr("disabled", true);
});

$("#show-subbasin-map").click(function(event) {
    map.removeLayer(fieldJsonp);
    map.addLayer(subbasinJsonp);
    $('#show-field-map').attr("disabled", false);
    $('#show-subbasin-map').attr("disabled", true);
});

Answer 1

SELECT Sn,sDayDate, GROUP_CONCAT(string SEPARATOR ' ') FROM table GROUP BY Sn;互动带有一系列功能：

Select

您可以在该选择上调用var select = new ol.interation.Select(); var features = selectInteraction.getFeatures();以取消选择所有功能：

clear()

Answer 2

Well, I would rather choose a way of removing interaction and assigning it again, like it is here.
