Loads an external SVG file via an Ajax request and appends it to each element in the collection. The full DOM tree from the SVG image will be appended to the collection’s elements. This is distinct from appending an image using the
image() element method, where only a single DOM element to represent the image is added.
callback function is called after this has completed. If the
replace argument is
true, the container element(s) will be emptied before the loaded content is appended.
callback is passed two arguments: 1) a collection of the new contents and 2) the XMLHttpRequest object used to load the file. Within the callback, the
this object will be the original collection.
