                                }

<button id="btnUntick" type="button" class="submit aui-button aui-button-primary" onclick="untick()">Un-tick all boxes</button>

The script seems to hang after the "Please Wait..." message turns on if no checkbox was ticked and there's nothing to untick. This can be confusing for the user.

To avoid this, I've inserted the following lines before the for loop:

    if (number_of_boxes == 0) {
        location.reload();
    } 

I've update the gist with the latest version of the macro that i'm using.

Beautiful script! Thank you very much. Working nicely on On-prem Confluence v. 7.2.1. To bad Confluence could not add this feature as default.

Updated script to handle failed AJAX

Also made a gist to tick all checkboxes on the page.
