I am attempting to transmit data to a dialog box within an Outlook web add-in.
var url = window.location.origin+'/dialog.html'
var dialog
Office.context.ui.displayDialogAsync(url2,
function (asyncResult) {
dialog = asyncResult.value;
dialog.messageChild('message')
});
This code opens a dialog box and tries to pass information to the dialog using the following Javascript:
Office.onReady().then(()=> {
Office.context.ui.addHandlerAsync(
Office.EventType.DialogParentMessageReceived,
onMessageFromParent);
});
function onMessageFromParent(arg){
console.log(arg.message)
document.getElementById('ID').style.display = 'none';
}
However, upon running this code, I encounter the error message:
TypeError: Office.context.ui.addHandlerAsync is not a function
Upon logging console.log(Office.context.ui), the output indicates:
OSF.DDA.UI.ParentUI
[[Prototype]]:Object
closeContainer:function(){ … }
displayDialogAsync:function(){ … }
openBrowserWindow:function(){ … }
__proto__:Object
It is evident that there is no addHandlerAync function found in Office.context.ui, despite it being recommended by Microsoft's documentation.
What could be causing this issue? Any help would be appreciated. Thanks
