In ol 3.10, I am trying to use this code to zoom, but it is not displaying my zooming rectangle.

ol.interaction.DragZoom.dragZoom= new ol.interaction.DragZoom ({
  condition: ol.events.condition.always,      
});

What is the possible reason?

  • in openlayer v3.13 its creating issue .. please try lower version ...say v3.9.0. I also faced the same issue . Later i found Openlayer3.13 having issue in Style . Thanks Pravin – Pravin Kumar singh Feb 29 '16 at 18:58

They have resolved the bug, now you just need to use this CSS to style your box:

.ol-dragzoom {
  border-color: red;
  border-width: 3px;
  background-color: rgba(255,255,255,0.4);
}

did you add the style stuff when initialising???? check this might help

myapp.Navigation.Tools.dragZoomInt = new ol.interaction.DragZoom({
    condition  : ol.events.condition.always,
    style      : new ol.style.Style({
        fill       : new ol.style.Fill({
        color      : 'rgba(255, 255, 255, 0.6)'
        }),
        stroke     : new ol.style.Stroke({
            color    : '#319FD3',
            width    : 3
        })
  })
});

  • when initialising your map, do you use the renderer option???? And if yes what do you asign there? – pavlos Oct 30 '15 at 15:47
  • I had some kind of this problem when using 'webgl'. Thats why I am asking. The piece of code you provide seems correct. Though , this is just the tree out of the forest. Unless you provide the whole code or better a fiddle we can not do much to help you. – pavlos Oct 31 '15 at 10:55
  • it is usual map init.( or I guess so) var map = new ol.Map({ layers: [ new ol.layer.Tile({ source: new ol.source.OSM() }) ], controls: ol.control.defaults().extend([ new ol.control.ScaleLine({units:'metric', className: 'ol-scale-line', target: document.getElementById('scale-line')}), overviewMapControl, new ol.control.FullScreen() ]), target: 'map', renderer: 'canvas', view: new ol.View({ center: ol.proj.transform([36.0, 39.0],'EPSG:4326', 'EPSG:3857'), zoom: 6 }) }); zoom bounding box has vanished. – atemiz88 Nov 1 '15 at 8:42
  • Within your code I dont see any interaction. Where do you initialise your interaction?????? check this fiddle jsfiddle.net/p_tsagkis/8o72zgun it is a combination of your code plus I have added the interaction. – pavlos Nov 1 '15 at 15:19

This worked for me

.ol-dragzoom {
    border: 3px solid red !important;
    background-color: rgba(255,255,255,0.4);
}
