Dojo/query and Webappbuilder layerlist widget (LayerListView.js)

TimJacobsen — Thu, 04 Jun 2015 17:46:36 GMT

I'm trying to modify LayerListView.js of the webappbuilder layer list widget, so the image of the noLegend-image class will change based on the layer.

To accomplish this I tried adding the else-if to the dojo query below. Based on the HTML/CSS in the attachment, how should the else-if be filled to populate the img class based on the tr class value. Maybe this is the wrong approach but it seems the most obvious.

Dojo Query:

var imageName:

if (layerInfo.isTable){

imageName = 'images/table.png';

}

else if query () == 'yourLayer' {

imageName = 'images/yourLayer.png';

}

else {

imageName = 'imageName = 'images/noLegend.png';

}

Tim,

Unless I am misinterpreting the code and your intent then what you are asking is not doable. You are asking for the proper code to query an attribute of a element that is yet to be created and added to the DOM. I think this is what you are after:

      var imageName;
      if (layerInfo.isTable) {
        imageName = 'images/table.png';
      } else if (layerInfo.id === 'yourlayer'){
        imageName = 'images/yourLayer.png';
      } else {
        imageName = 'images/noLegend.png';
      }
