Question

I”m building a plugin for Photoshop, which is based on layers. To do this, I need to build an array with each layer which returns true when going through a function (checking the name for matches).

How could I basically “recursively” go through the object, and child objects, until I’ve been through everything? (Putting “selected” items in an array in the process).

The object is just a plain javascript object, with tons of objects in it (and further more inside it).

Try this:

var isASelectedLayer = function(element) {
    ...
}
var objectWithLayers = {...}

var selected = [];
var lookForSelectedLayers = function(o) {
    for(element in o) {
        if(isASelectedLayer(o[element]))
            selected.push(o[element]);
        else
            lookForSelectedLayers(o[element]);
    }
};
lookForSelectedLayers(objectWithLayers);
