jquery - How can I setDraggable(false) on layer by name -

i have problem in program. want setdraggable of layer false. have no idea how set it. created layer when user clicks button. , layer has different name. name of layer set "abc"+i. variable increment. i'm using jquery-1.8.3.js, jquery-ui.js, , kinetic-v4.3.2-beta.js.

document.getelementbyid('computer').addeventlistener('click', function(e) {     draw(images);     layer.add(img);     stage.add(layer);     i++; }, false); 

and here code of function draw

function draw( images ) {     img = new kinetic.rect({        x: 50,        y: 150,        width: 50,        height: 50,        fillpatternimage: images.abc,        name: "abc"+i,        draggable: true     }); }
