Obtaining IDs of Divs that have been Dragged into a Drop Zone upon Clicking a Button using JavaScript

Obtaining IDs of Divs that have been Dragged into a Drop Zone upon Clicking a Button using JavaScript

I'm currently working on a solution to extract the ids of dragged divs once they have been placed in the drop zone.

Each drag component is assigned an id ranging from drag1 through drag8, while the drop zone is labeled as div drop zone. Since there are no divs in the drop zone at page load, I am planning to collect the ids using a save button along with text box input and dropdown menu selection.

Here's the snippet of code that I've experimented with:

$(document).ready(function() {
    $("#dropzone div").click(function() {
        var index = $("#dropzone div").index(this);
        $("#dropzone_drag").html("Index " + drag + " was clicked");
    });
});

Additionally, I have integrated jQuery for the text box functionality, which is functioning smoothly:

$(document).ready(function() {
    $('#save').click(function() {
        alert($('#name').val());
    });
});

Could you please advise me on how to retrieve the ids of dragged divs once they have landed in the drop zone?

Answer №1

Experimenting with different ideas, I ended up with this solution:

var ids = {};
$("#dropzone>div").each(function(i){
    ids[i] = $(this).prop('id');
});

Currently, it displays as undefined, but I successfully linked it to the save button to prevent it from appearing when the page is opened.

Any recommendations or suggestions?

From my understanding, .index(this) gives you the position of the element in relation to the list "#dropzone div", which may not necessarily have the elements arranged in the order you desire. However, if all your elements share a common class like ".foo_bar", it might be simpler to determine the id based on the clicked element.

Alternatively, if you are using this within a function and it refers to one of your "drags", extracting the id from this could be easier than trying to calculate indexes.

You could attempt this approach and see if it yields better results.

ids = {};
$("#dropzone>div").each(function(){
    ids[$(this).prop('id')] = $(this).prop('id').replace(/[^0-9]/g, '');
});

The use of .replace() in the code snippet indicates that we are removing characters (specifically anything that is not a number) from the string, thus obtaining the actual numeric value instead of its position in the DOM.

If I have misunderstood your issue, please clarify any misconceptions and I can revise the response accordingly. Additionally, an HTML representation of the zones would be helpful for further assistance ;)

After trying different approaches, I found a solution that worked for me:

  <script>
  var div = document.getElementById('dropzone')
  </script>

I also added the following code to a button:

alert( div.innerHTML )

This allowed me to extract specific information from the div's HTML content, which I then pushed to the database.

Thank you to everyone who provided input and advice.
