Hello I am working on a project where i have 4 tabs. And i am taking user input through text boxes ,drop downs and switches and my output gets stored in the file in json format . Right now after taking input and clicking the submit button data gets stored in the file. But if I want to take new input the previous inputs are already present on ui. My question is , can we refresh the page? And after refreshing , will all the input fields get cleared? Is there any node available which can clear the past inputs? If yes then how to use it.

Does the solution suggested on the thread where you asked the same question yesterday not work?

What have you tried?  
If you want to send a message to a node how do you think you would do it?

The thread states you need send the form parts an empty msg.payload. Have you tried that?

I would also change the text on the button to 'SUBMIT', add a text msg saying the data has been submitted, and add another button 'RESET' to clear out the data.

It isn't clear what you are trying to do. Please start a new thread with a description of your problem rather than adding your question to an old thread. If you are just trying to clear the text shown on a dashboard input node then probably all you need do is to send it a message with an empty string in the payload.

The original question on this thread is

> [@Vishakha](#):
>
> I am working on a project where i have 4 tabs. And i am taking user input through text boxes ,drop downs and switches and my output gets stored in the file in json format . Right now after taking input and clicking the submit button data gets stored in the file. But if I want to take new input the previous inputs are already present on ui. My question is , can we refresh the page? And after refreshing , will all the input fields get cleared

Is that the same problem you want a solution to? If not then please start a new thread.
