Method Overview

Method Details

clone(elem){Object}

Use this method to deeply clone objects with properties that are computed or have their own clone() method. For example, if you are creating an object that stores an initial extent and a spatial reference for your application, you can use esriLang.clone(initialProps) to clone this object so that the extent and spatialReference are properly cloned.

Parameter:

elem Object The object to be cloned.

Returns:

Type	Description
Object	A clone of the object.

Example:

require(["esri/core/lang"], function(esriLang) {
 var initialProps = {
  extent: appExtent, // app initial extent
  spatialReference: spatReference // app spatialReference
 };
 // Creates a deep clone of the object
 var clonedInitialProps = esriLang.clone(initialProps);
});
