[ANSWERED] javascript – filter function with radio button

Question 1

A quick auto-format of your code shows that, where you have indentation indicating a child, .cliente is not a child of #elenco because you have <div id="elenco"></div>.

Your HTML:

<div id="elenco"></div>
    <div class="cliente">
    </div>
</div>

(with an error on the last </div>)

reformats as

<div id="elenco"></div>
<div class="cliente">
</div>
</div>

so it’s easier to see that cliente is not a child of elenco.

Secondly, your selector is $("#elenco > .desc") where > means a direct-descendent (immediate child or similar term).

This is the same as $("#elenco").children().filter(".desc")

But .cliente is the direct-child and .desc is a child of .cliente – so your selector needs to be #elenco .desc or #elenco > .cliente > .desc

~~Thirdly, you filter by checking .desc .value is <10 – but the .value is “PROD” or “TEST”, not numeric.~~

Question was updated:

Thirdly, you filter by return this.value

However, .filter requires a boolean to filter, so “truthy” this.value will always be true.

Looks like you just need to compare, as in:

var v = b.value;
return this.value == v;

For the snippet below I’ve changed this to just match on value using an attribute selector rather than filter.

Matching on attribute doesn’t need the if (value== as it could be just

$("#elenco .desc[value='" + this.value + '"]").show();

but left as 2x if in the snippet in case there’s some other filter to be applied.

$(function() {
  $('input[name="test"]').on('change', function(a, b) {
    var value = this.value;
    console.log(value)
    $('#elenco .desc').hide();
    if (value == 'All') {
      $('#elenco .desc').show();
    }
    if (value == 'PROD') {
      //$('#elenco .desc').filter(function(a, b) {
      //  var v = b.value;
      //  return 10 > v;
      //}).show();
      $('#elenco .desc[value="PROD"]').show();
    }
    if (value == 'TEST') {
      //$('#elenco .desc').filter(function(a, b) {
      //  var v = b.value;
      //  return v >= 10 && v <= 20;
      //}).show();
      $('#elenco .desc[value="TEST"]').show();
    }
  });
});

Question 2

try changing the ‘change’ to click like i did here below and adding else if, instead of 3 ‘if’ s

 $(function () {
            $('input[name="test"]').on('click', function (a, b) {
                var value = this.value;
                $('#elenco > .desc').hide();
                if (value == 'All') {
                    $('#elenco > .desc').show();
                }
               else if (value == 'PROD') {
                    $('#elenco > .desc').filter(function (a, b) {
                        var v = b.value;
                        return 10 > v;
                    }).show();
                }
              else if (value == 'TEST') {
                    $('#elenco > .desc').filter(function (a, b) {
                        var v = b.value;
                        return v>=10 && v <= 20;
                    }).show();
                }
            });
        });

Question 3

All I need is a function to filter my page based on the text contained in the div class desc that is the word PROD or test. I had thought of something like the one contained in the script tags but I can’t get it to work.

 $(function () {
      $('input[name="test"]').on("click", function (a, b) {
        var value = this.value;
        $("#elenco > .desc").hide();
        if (value == "All") {
          $("#elenco > .desc").show();
        } else if (value == "PROD") {
          $("#elenco > .desc")
            .filter(function (a, b) {
              var v = b.value;
              return this.value;
            })
            .show();
        } else if (value == "TEST") {
          $("#elenco > .desc")
            .filter(function (a, b) {
              var v = b.value;
              return this.value;
            })
            .show();
        }
      });
    });

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="radio" value="All" checked name="test" /><label>All</label>

            </li>
          </ul>
        </div>
      </div>
    </div>

I tried the function above which I can’t get it to work. In practice, based on the selection button, only the results associated with it must appear and by default, the selected button must be ALL.
