Preventing Posting

[Mattia]

Hello, I'm trying to prevent chat posting, I mean when user click send button (or type keybord enter) I want in some cases to prevent the post of the message.
Something like this is not working (the message is posted in chat)

$("#chat").kendoChat({
    post: function(e) {
        e.preventDefault();       
    }
});

Is that a bug? Or there is a different approach to accomplish this task?
Thanks,
Mattia

Hello Mattia,

Currently, the Chat post and sendMessage events cannot be prevented. I have logged an enhancement issue in the official Kendo UI GitHub repository and you can start tracking its progress from here(#4609).

One thing that you can try to achieve similar result is to subscribe to the sendMessage event and conditionally set the text and message box to empty. In this way, no message will be rendered in the Chat view:

sendMessage: function(e) {
  if(e.text == "not allowed") {
    e.text = "";
    e.sender.messageBox.input.val("");
  }
}

// Also to consider...

// jQuery

const chatEl = $('##chatWidget');

// set your conditions to disabled / enable

chatEl.find('button').prop('disabled', true);
