Subject: Re: [Users] Question on multiple filters for a LayerContainer control
We had a similar challenge here, one of our web programmers helped me figure
this out.
In this situation, I wanted all layers with a name that did NOT include
"Balance", "Ratio", or "Highlight" to appear in this layercontainer:
loader: {
filter: function(record) {
var myarr = new Array();
myarr[0]=record.get("layer").name.indexOf("Balance");
myarr[1]=record.get("layer").name.indexOf("Ratio");
myarr[2]=record.get("layer").name.indexOf("Highlight");
if(myarr[0]==-1 && myarr[1]==-1 &&
myarr[2]==-1){
return true;
}else{
return false;
}
}
Not sure if it's THE best solution, but it does work and it's fairly simple to
add additional words to search for.
Hope this helps,
Ryan

I am faily new to GeoExt and openlayers. What I am trying to do is add multiple
filters to a layercontainer so that I can add multiple layers to each group.
Not sure if this is the best way to do this but what I want to do is add all my
Street Labels to a group called "Labels" I can add one no problem called
Overview Streets with the following code, but I need to add additional layers
like one called Quadrant Streets. When I try to modify the filter code to add
additional names it doesn't work and I get javascript errors. Any help
appreciated!
//Define Layer List Control - Tree Control for Legend Control
var layerList_Labels = new GeoExt.tree.LayerContainer({
text: 'Labels',
layerStore: mapPanel.layers,
leaf: false,
expanded: false,
loader: {
filter: function(record) {
return record.get("layer").name.indexOf("Overview Streets") !== -1
(need to add Quadrant Streets here also)
}
}
});
