jquery - Select element by id name ending on OpenLayers -

-

i trying select element id on openlayers map. have checked element id "openlares_map_4_openlayers_container" number changes (4 8 or 10). trying select element jquery selector finds element ends (see link).

but doesn't seem work. , example can seen in jsfiddle following javascript code:

// osm var osmlayer = new openlayers.layer.osm("osm map");  // map var map = new openlayers.map('mapdiv', {     layers: [osmlayer],     center: new openlayers.lonlat(0, 0),     zoom: 0 });  // elements var = document.getelementsbytagname("*"); (var i=0, max=all.length; < max; i++) {     console.log('document.elements: ' + + ' -> ' + all[i].id) }  // select elements var mapcontainer = document.getelementbyid("openlayers_map_4_openlayers_container"); $("#tag1").text("    ->     "+mapcontainer); console.log('mapcontainer: ' + mapcontainer);  var id_ol_container = $("div[id$='_openlayers_container']");    // http://api.jquery.com/attribute-ends-with-selector/ $("#tag2").text("    ->     "+id_ol_container); console.log('id_ol_container: ' + id_ol_container);

does know it's wrong jquery?

important lesson: read api documentation before diving deep hacking. whole parsing logic can replaced with:

console.log('id_ol_container: ' + map.layercontainerdiv.id);

here's working jsfiddle demonstrates in action

another important question why think need id of element. not depending on element id names you'd make code more clean , reliable. openlayers code should not mixed dom level code allow independently evolving both.
