修改交互不起作用

Question

在Select交互中修改与pointerMove条件的互动会产生TypeError：this.a[d] is undefined (c)};l.update=function(b,c){var d=ma(c);Wd(this.a[d].slice(0,4),b)||(this.remove...

var point_source=new ol.source.Vector();
var PointVectorLayer = new ol.layer.Vector({
    source: point_source

var layers = [PointVectorLayer];

Answer 1

因此，基于评论和修改，“如何抓住拖动完成时刻”的答案是：您可以对此事件采取一些措施：

app.Drag.prototype.handleUpEvent = function(evt) {

    console.info(evt);
    //some action

    this.coordinate_ = null;
    this.feature_ = null;
    return false;
};
