How to Reload Web Application using Directline Webchat?


How to Reload Web Application using Directline Webchat ?

Or Is there any way to call Javascript function after Directline Webchat recieve response from Bot?


Solution

  • You could use the WebChat control's BackChannel for this:

          const user = {
            id: 'userid',
            name: 'username'
          };
          const bot = {
            id: 'botid',
            name: 'botname'
          };
    
         const botConnection = new BotChat.DirectLine({
            secret: 'SECRET'
          });
    
          BotChat.App({
            bot: bot,
            botConnection: botConnection,
            user: user
          }, document.getElementById('BotChatGoesHere'));
    
          botConnection.activity$
            .filter(function (activity) {
              return activity.type === 'event' && activity.name === 'changeBackground';
            })
            .subscribe(function (activity) {
              console.log('"changeBackground" received with value: ' + activity.value);
              changeBackgroundColor(activity.value);
            });
    
          function changeBackgroundColor(newColor) {
            document.body.style.backgroundColor = newColor;
          }
    

    This example shows how a bot could send a changeBackground event to WebChat and have the backgroundColor of the page changed.

    From: https://github.com/Microsoft/BotFramework-WebChat/blob/master/samples/backchannel/index.html

    Instead of a changeBackground event, you can send a reloadPage event and call location.reload() in javascript.
