displayDialog method return value causes error -1700 when used as string argument

Question

When I try printing the Var 'password' it says

Error -1700: Can't convert types.

var app = Application.currentApplication();
app.includeStandardAdditions = true;


var text = Application('System Events')
//prompt
var password = app.displayDialog('enter your password', {defaultAnswer: " "});
text.keystroke(password)
//returned message is Error -1700: Can't convert types.

Answer 1

The displayDialog command returns an AlertReply record, which looks like this in JXA:

{"buttonReturned":"OK", "textReturned":"password"}

To get the value entered in the dialog, try appending .textReturned to the displayDialog invocation, like this:

var password = app.displayDialog('enter your password', {defaultAnswer: " "}).textReturned;
