Checking to see if dijit/form/CheckBox is checked

Anonymous User — Mon, 23 Sep 2013 17:58:43 GMT

Given:

function updateLayerVisibility() {
        var inputs = dojo.query(".list_item"), input;
        visible = [];
        for (var i=0, il=inputs.length; i<il; i++) {
          if (inputs.checked) {
            visible.push(inputs.value);
          }
        }
         //if there aren't any layers visible set the array value to = -1
        if(visible.length === 0){
          visible.push(-1);
        }
//alert(visible);
        layer.setVisibleLayers(visible);
      }

--AND--

<input data-dojo-type="dijit/form/CheckBox" checked="checked" class='list_item' id='l0' value=0 onclick="app.updateLayerVisibility()">

The javascript code is not returning the checked status of the CheckBox. Ideas?

Thanks!

Instead of using dojo.query, try using dijit/registry/findWidgets instead.

Thanks for the quick reply, Ken. Is there a real-world example for this?

Thanks!

So I guess a better question, given my code of:

<label class="chkLabel"><input data-dojo-type="dijit/form/CheckBox" checked="checked" class='list_item' id='l0' value=0 onclick="app.updateLayerVisibility()">Facilities</label>

what would be the formNode as prescribed in: var formWidgets = registry.findWidgets(formNode);

Yup, that worked....thanks for the tip

var inputs = registry.findWidgets(dom.byId("theDivContainingTheCheckBoxWidgets"));
