I tried the exampels in the docu https://docs.google.com/document/d/10fmlEYIHcyead_4R1S5wKGs1t2I7Fnp_PaNaa7XTEk0/edit# in the section @JsFunction but it gives only ideas to call java function from javascript.
I have a javascript file included in my GWT app with the following code:
var client = new Circuit.Client({
client_id: '78cafde2f6854ad5ad80a67c532687bc',
scope: 'READ_USER_PROFILE,READ_CONVERSATIONS',
domain: 'circuitsandbox.net'
});
function startLogon() {
client.logon()
.then(user => console.log('Logged on as ' + user.displayName))
.then(client.addEventListener('itemAdded', item => console.log('itemAdded event received:', item)))
.then(client.getConversations)
.then(conversations => {
console.log('Retrieved ' + conversations.length + ' conversations');
return client.addTextItem(conversations[0].convId, 'Hello World');
})
.then(item => console.log('Msg sent on ' + (new Date(item.creationTime)).toString()))
.catch(console.error);
}
Now i want to call the function 'startLogon()' - my be with a wrapper - from my app using jsInterop annotations. I tried the two following examples without any success:
Implement Javascript Function Callback with GWT JsInterop
JsInterop wrapping a javascript function property
I have to say, that my JavaScript knowledge is very bad.
Can someone give me a code example? Many thanks in advance!
Add this static method to any class.
This will work, although you cannot do anything with the returned promise. If you want to use the returned promise I recommend adding elemental2 and use
Promise startLogon()
instead so you can consume it like this:
