单击按钮删除 div（更改 id）

Question

I'm generating div with class and id changing. They are all the same and each one has a delete button. I want to delete the div in which the clicked button is. Each button as the id "delete_index" in a "past_experience_index" div. In fact, when i click on delete_2, i want past_experience_2 to be deleted.

I tried several things but it does not work...

Here is the PHP:

<div class="experiences_container">
    <?php 
    if (!empty($experiences)) {
        $index = 0;
        foreach ($experiences as $key) {
        ?>
            <div id="past_experience_<?=$index?>" class="past_experience">
                <div class="experience_header">
                    <div>
                        <label for="team">Nom de l'équipe</label>
                            <input class="team" name="team_<?= $index ?>" value="<?= $key['team-name'];?>"/>
                    </div>
                    <div>
                        <label for="role">Rôle dans l'équipe</label>
                            <input class="role" name="role_<?= $index ?>" value="<?= $key['team-role'];?>"/>
                    </div>
                </div>

                <div class="experience_textarea">
                    <label for="description">Description du rôle</label>
                    <textarea class="description" name="description_<?= $index ?>"><?= $key['team-description']; ?></textarea>

                    <label for="palmares">Palmarés avec l'équipe</label>
                    <textarea class="palmares" name="palmares_<?= $index ?>"><?= $key['team-palmares']; ?></textarea>
                </div>
                <p id="delete_<?=$index?>" class="delete_button">supprimer</p>
            </div>  
        <?php
        $index++;
        } 
    } else {
    ?>
    <div><p>Vous n'avez encore rentré aucune expérience</p></div>
    <?php 
}?>
</div>

So as a JavaScript beginner, i tried a for() with the php index value limit but it doesn't work. The $("div").remove(past_experience_index) works, but i can't have the actual index.

Thanks a lot

Answer 1

Define an onclick function on button click pass $index as a function argument.

<p id="delete_<?=$index?>" class="delete_button" onclick="del_div_fun('<?php echo $index ?>')">supprimer</p>

Now you have to define this function in javascript like.

function del_div_fun(index_val){
var div_id = 'past_experience_'+index_val;
$('#'+div_id).remove();
  }//end of function del_div_fun

Please use jquery library

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>

If your using jquery you don't really need to worry about ids. You can use jQuery to find the parent and remove it that way.

Something like this:

 $(".delete-btn").click(function(){ $(this).parent().remove() })

 <script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script> <div style="padding:10%;background-color:lightgrey;text-align:center;"> <p style="cursor:pointer;" class="delete-btn">Delete</p> </div>

Answer 3

Probably you don't need to duplicate indexes everywhere.

And you can avoid adding jquery into your page.

 <script> function deletePastExperience() { var experiencesContainer = document.querySelector('.experiences_container'); var elementToRemove = document.getElementById(event.target.parentElement.id); experiencesContainer.removeChild(elementToRemove); } </script>

 <p onclick="deletePastExperience()" class="delete_button">supprimer</p>
