 have been facing this issue for almost a week now. I can't seem to have my checked radio box to toggle between one another. By default, the radio button is set to checked for the "Allow Partial Download". I want to save the checked value so, I stored the key value pairs in the local storage for the Full Download when it is being toggled.

Upon rendering/refresh, the Full Download should be checked. However this does not work.. and instead I kept getting this error after retrieving the local storage key value pair. (Retrieving the key value pair works)

I have tried using [dojo/DomReady!] but it doesn't work. Placed everything into the render function. And also a few jQuery methods which also didn't work...

So basically I have been getting this error, but my DOM has already been rendered as I could access the element.

The _renderDownloads is binded to an onClick function and renders whenever the page loads.

TypeError: Cannot read properties of undefined (reading 'checked'

 

HTML Code:

      <form class="g-item-title" style="color: #005e95">
        <input type="radio" id="checkboxPartialDownload" data-dojo-attach-event="onClick: _test" style="cursor: pointer;" name="downloadValue" value="partialDownload" checked>
        Allow Partial Download

        <br>

        <input type="radio" id="checkboxFullDownload" data-dojo-attach-event="onClick: _renderDownloads" style="cursor: pointer;" name="downloadValue" value="fullDownload" >
        Allow Partial + Full Download
      </form>

 

Function that is being rendered

  _renderDownloads: function(){

        //$('#partialDownload').attr('checked', false);
        //$('#fullDownload')[1].checked; Both these options doesn't work for either

        let title = this.item.title;
        let fileid = this.item.fileid

       if(localStorage.getItem(`${title} ID:${fileid}`) === "AllowFullDownload"){
        $('#partialDownload').prop('checked', false); //Doesn't work
        $('#fullDownload').prop('checked', true); // Doesn't work
       }

        var radioButtonValue = $("input[type='radio'][name='downloadValue']:checked").val(); 
        //console.log('First render'+ radioButtonValue)

        if(radioButtonValue ==="fullDownload"){
          localStorage.setItem(`${title} ID:${fileid}`,"AllowFullDownload")
        }

This is a snippet of the code where it is being rendered from. Also I do not know how to wrap this in a with ready, are there any other sample codes for this? As this code is slightly different from the documentation.

        let dataTitle = hit.sort[0];
        let dataid = hit._source.fileid;

          $('#partialDownload').prop('checked', false);
          $('#fullDownload').prop('checked', true);
         }

          this._renderDownloadDropdown(item,links)
        }
