Confirm before deleting annotation

[Matt Parizeau]

Q:

I was wondering if it’s possible to prevent the deletion of annotations on pressing the delete key. I need to raise a dialog to confirm deletion rather than deleting the annotation directly.

A:

You can use the following code to insert your own confirmation dialog:

$(document).on('viewerLoaded', function() {
    var deleteKey = 46;
    var originalKeyDown = window.Tools.AnnotationEditTool.prototype.keyDown;

    window.Tools.AnnotationEditTool.prototype.keyDown = function(e) {

        if (e.which === deleteKey && !window.utils.isEditableElement($(e.target))) {
            if (myConfirmationFunction()) {
                originalKeyDown.apply(this, arguments);
            }
        }
    };
});
