Topic: [Bug?] Unable to get array as output for multiple select

Jordan Mack pro asked 1 month ago


Expected behavior

Output of select as array:

document.getElementById('newBudgetEmployee').value // output: ['value1','value2']

Actual behavior

Only a singular selected value is outputted:

document.getElementById('newBudgetEmployee').value // output: 'value2'

Resources (screenshots, code snippets etc.)

Here is my setup for the select:

function called to get options, dispose of current select and reinitialize:

function fetchEmployees() {
return fetch(FETCH + '/generic/employees.php')
    .then((resp) => {
        if (resp.ok) return resp.json();
        else throw new Error("Error fetching employees");
    })
    .then((p) => {
        let eSelect = document.getElementById('newBudgetEmployee');
        let employeeOptions = p.map((e) => {
            let op = new Option([e.first, e.last].join(" "), e.id);
            return op.outerHTML;
        });

        let firstOp = new Option("", "");
        firstOp.hidden = true;
        employeeOptions.unshift(firstOp.outerHTML);

        $('#newBudgetEmployee').empty().append(employeeOptions);

        mdb.Select.getInstance(eSelect).dispose();
        let eSel = new mdb.Select(eSelect, {
            filter: true,
            container: '#newBudgetModal',
            multiple: true,
        });

    }).catch((e) => {
        alertr.error(e);
    });
}

HTML:

<div id="newBudgetModal" class="modal" tabindex="-1">

Here is a snippet: https://mdbootstrap.com/snippets/standard/jps_mack/4286546#html-tab-view

This functionality seems to be broken after updating from MDB5 4.2.0 to MDB5 4.4.0 as my other pages no longer work as intended either

UPDATE: After reverting to 4.2.0 I can confirm this isnt version specific. I am still unsure what is causing this issue

I've tried using your snippet with MDB 4.2.0 it didn't work either. And actually, it is not supposed to. Because the select component is a component that we wrote so you need to check its value not the value of HTML default select below that is used for initiation.

I've adjusted your snippet to demonstrate that: https://mdbootstrap.com/snippets/standard/kpienkowska/4288713
