我需要制作永久弹出窗口，但只能在鼠标事件时显示它，我找到了一个示例但没有适应成就： http: //openlayers.org/dev/examples/osm-marker-popup.html
任何人都可以帮助我永久弹出弹出窗口，谢谢。

var markers = new OpenLayers.Layer.Markers( "Ruta" );
$.each(info, function(i, data){
var size = new OpenLayers.Size(21,25);
var offset = new OpenLayers.Pixel(-(size.w/2), -size.h);
var icon = new OpenLayers.Icon('/openlayers/img/data.png',size,offset);

var centrar = lonlat.transform(proj_1,proj_2);
mapa.addLayers([osm,markers]);
mapa.setCenter(centrar, 5);
mapa.addControl(new OpenLayers.Control.LayerSwitcher());
