Check if the selected layer contains a rectangle Extendscript

Question

Hey,I can't find how to check if a layer has a certain proprety from this listIn my case, I want to check if the selected layer contains a rectangle, here's my code:thisComp = app.project.activeItem;
curLayer = thisComp.selectedLayers[0];

iconbutton1.onClick = function() {
    if (curLayer instanceof ShapeLayer) { //check if it's a shape layer

if () { // check if it contains a rectangle
            alert("this layer has rectangle");   
        } else {
            alert("this layer doesn't has rectangle");
        }

} else {
        alert("Please select a shape layer");
    }
}Thanks in advance,RedyMotion

There are probably a lot of ways you could accomplish this, and it could get fairly complex to do a comprehensive check, but here I just for looped through the "Contents" property of the layer to see if it contains a property called "Rectangle 1" which is the default name when a new rectangle layer is created.

var thisComp = app.project.activeItem;
var curLayer = thisComp.selectedLayers[0];
var rectProp = false;

iconbutton1.onClick = function() {
    if (curLayer instanceof ShapeLayer) {
            for (i = 1; i <= curLayer.numProperties; i++) {
                if (curLayer.property("Contents").property(i).name == "Rectangle 1") {
                    alert("This layer does have a rectangle!");
                    rectProp = true;
                }
            }
            if (rectProp == false) {
            alert("This layer doesn't have a rectangle.");
            }
        }
    }

You simply iterate through the properties and check against the type. Not sure what else you need to know here. Mylenium
