How to clear text input after submitting?

Hi everyone,

I have created a drop-down linked with text input. I am able to search by field1, field2, field3. However, I have an issue to clear text input after submitting:

For example:
1) I enter a text in “search by field1” and submit.
2) It displays the line
3) I go on “Search by field2”
4) I return on “Search by field1” and the text that I have written at 1) is still in the text input

I want that when I return in "Search by field1", the text was cleared and displays the default value *.
I tried to create a clear button but didn’t work:
I add this to my code :

<html>
      <input type="button" value="Clear" id="clear></input>
      </html>

and the javascript function clear.js :
var input = document.querySelector('#clear');
var textarea = document.querySelector('#output');

input.addEventListener('click', function () {
    textarea.value = '';
}, false);

Is there another way to clear text input ? Could you please help me with that ?
Thanks in advance

I would recommend reviewing the component reference for Splunk Web. Using Javascript you can select splunk object by id and most Splunk objects how multiple event listeners.

//using TextInputView and MultiDropdownView

var hostInput = splunkjs.mvc.Components.getInstance("host-input");
var dropdownManager = splunkjs.mvc.Components.getInstance("multidropsearch1");

dropdownManager.on('change', function() {
  hostInput.settings.set("value", '')
})

This is only a snippet. If you want to add an event listener I would start by extending backbone object to added an on click event. Just the on change should meet your need.
