Recently a fellow college wanted to disable the inline notes control. Requirement was to still be able to see all the notes but not add or edit existing notes inline. With RU12/Polaris the notes control changed, therefor existing solutions for disabling the control doesn’t work. We also need to take cross browser support into consideration.

Here is a small script you can place on the form to disable the notes control. Create a new javascript web resource, add it to the form script libraries and call the “Utils.disableNotesControl” function.

var Utils = Utils || {};

Utils._disableNotesControlComponents = function (noteControlId) {
    var iframe = document.getElementById(noteControlId);
    var iframeDoc = iframe.contentDocument || iframe.contentWindow.document;

    // we'll only disable textboxes, we'll leave the delete/add attachments etc etc enabled.
    var controls = iframeDoc.getElementsByTagName("textarea");
    for (var i = 0; i < controls.length; i++) {
        controls[i].disabled = true;
    }
}

Utils.disableNotesControl = function () {
    var controlId = "notescontrol" // this is the default id of the notes control 

    var iframe = document.getElementById(controlId);
    // onreadystatechange works with IE but not other browsers 
    iframe.onreadystatechange = function () {
        if (iframe.readyState == "complete") { Utils._disableNotesControlComponents(controlId); }
    }

    // this works with chrome 
    iframe.onload = function () {
        Utils._disableNotesControlComponents(controlId);
    }
}
