Return Value

A string in the RFC 1766 Language tag format, such as en-US.

function sayHelloWithDisplayLanguage() {
    var myDisplayLanguage = Office.context.displayLanguage;
    switch (myDisplayLanguage) {
        case 'en-US':
        case 'en-NZ':
            write('G\'day mate!');
// Function that writes to a div with id='message' on the page.
function write(message){
    document.getElementById('message').innerText += message;
