Javascript Duplicate Criteria1 to Criteria2

[Klib7]

I have a search criteria that needs the same data in both criteria fields in order to function properly, but I want to hide the second field and have it automatically enter whatever number the user inputs into Criteria1.

I've tried a few older Javascript codes that I found on this forum but none of them have worked. 

Any assistance would be amazing!

Hello @Klib7,

Do you need to apply this to 2 separate search fields or 1 search field with Criteria?

It is important to reference the fields. 

For case 1 you can add this code in the Footer section of the Search page:
 

<script>
if (document.DataPageReadyHandler == undefined) {
    const DataPageReadyHandler = (e) => {
     if (e.detail.appKey != '[@cbAppKey]') { return }
      
        const fieldOne = document.querySelector('#Value1_1');
        const fieldTwo = document.querySelector('#Value2_1');
        fieldOne.addEventListener('change', function(){
            fieldTwo.value = event.target.value;
        })
    }
    
    document.addEventListener('DataPageReady', DataPageReadyHandler)
    document.DataPageReadyHandler = 'Enabled'
    }
</script>

For case 2:
 

<script>
if (document.DataPageReadyHandler == undefined) {
    const DataPageReadyHandler = (e) => {
     if (e.detail.appKey != '[@cbAppKey]') { return }
     
        const criterionOne = document.querySelector('#Value1_1');
        const criterionTwo = document.querySelector('#Value1_2');
        criterionOne.addEventListener('change', function(){
            criterionTwo.value = event.target.value;
        })
    }
    
    document.addEventListener('DataPageReady', DataPageReadyHandler)
    document.DataPageReadyHandler = 'Enabled'
    }
</script>

If the code doesn`t work, please provide a screenshot of the Search page as on the screenshots examples that I added in this post above.
