element.left
Read-only property; a float value that represents the left side of the element. The value of element.left is relative to the upper left of the Stage for elements that are in a scene and is relative to the symbol’s registration point (also origin point or zero point) if the element is stored within a symbol. Use document.setSelectionBounds() or document.moveSelectionBy() to set this property.
The following example illustrates how the value of this property changes when an element is moved:
// Select an element on the Stage and then run this script.
var sel = fl.getDocumentDOM().selection[0];
fl.trace("Left (before) = " + sel.left); fl.getDocumentDOM().moveSelectionBy({x:100, y:0});
fl.trace("Left (after) = " + sel.left);See the element.elementType example.
