Stack Overflow Asked by dgoldfeder on January 14, 2021
I display a user list and at the end of each user I add 2 buttons, one for edit and the other to delete the user, my big problem is that only the buttons of my first element of my list work.
This code displays my list
<tbody>
<?php for( $i = 0; $i < count($users->datos); $i++ ): ?>
<tr>
<td style="padding: 0 20px;"><?php echo $users->datos[$i]["email" ]; ?></td>
<td style="padding: 0 20px;"><?php echo $users->datos[$i]["paterno"]; ?></td>
<td style="padding: 0 20px;"><?php echo $users->datos[$i]["materno"]; ?></td>
<td style="padding: 0 20px;"><?php echo $users->datos[$i]["nombre" ]; ?></td>
<td style="padding: 0 20px;">
<?php
echo preg_replace(PHONE_NUMBER, "($1) $2-$3", $users->datos[$i]["movil"]);
?>
</td>
<td id="botones">
<form id="ed" method="POST">
<input type="hidden" id="token" name="token" value="<?php echo $users->datos[$i]["tokenA"]; ?>">
<button type="submit" id="<?php echo $users->datos[$i]["id"]; ?>" class="buttonDelete"><i class="fas fa-trash-alt"></i></button>
<button type="submit" id="<?php echo $users->datos[$i]["id"]; ?>" class="buttonEdit" ><i class="fas fa-edit" ></i></button>
</form>
</td>
</tr>
<?php endfor; ?>
</tbody>
And this is my javascript code
const formEditDel = document.querySelector('form#ed');
const userDel = formEditDel.querySelectorAll('[class="buttonDelete"]')
const userEdit = formEditDel.querySelectorAll('[class="buttonEdit"]')
eventListeners();
function eventListeners(event) {
userDel.forEach(button => {
button.addEventListener('click', markDeleted);
});
userEdit.forEach(button => {
button.addEventListener('click', userEdited);
});
}
I really don’t know what to do, so any suggestion will be appreciated.
Thanks to @Taplar and @imvain2 I could get an answer to this question and understand how this works. THANK YOU GUYS!
Here is the final code
const userDel = document.querySelectorAll('.buttonDelete');
const userEdit = document.querySelectorAll('.buttonEdit');
eventListeners();
function eventListeners(event) {
userDel.forEach(buttonDel => {
buttonDel.addEventListener('click', markDeleted);
});
userEdit.forEach(buttonEdit => {
buttonEdit.addEventListener('click', userEdited);
});
}

Since every row contains a separate form, so using an id to select them will only select the first one.
So, you can replace this
const userDel = formEditDel.querySelectorAll('[class="buttonDelete"]')
const userEdit = formEditDel.querySelectorAll('[class="buttonEdit"]')
With this
const userDel = document.querySelectorAll('[class="buttonDelete"]')
const userEdit = document.querySelectorAll('[class="buttonEdit"]')
Or you can replace this
<form id="ed" method="POST"> ... </form>
With this
<form class="ed" method="POST"> ... </form>
And then select the form using class
const formEditDel = document.querySelector('form.ed');
