Is there a way to use Jquery to remove an editable div when it is clicked on and the Delete key on the keyboard is pressed?

Question

Is there a way to use Jquery to remove an editable div when it is clicked on and the Delete key on the keyboard is pressed?

Having a draggable div with the attribute contenteditable set to true, I can activate content editing by double-clicking on it. However, I also want to be able to delete the entire div by simply clicking on it and then pressing the Delete key on the keyboard. How can I achieve this? Specifically, how can I ensure that when I am writing something inside the div and press the Delete key, only the text is deleted, not the entire div itself?

Below is the HTML code:

$(document).ready(function() {

  $('.draggable').draggable({
    containment: "parent"
  });

  $(".draggable").resizable();

  $('#MyFirstDiv').click(function() {
    //PLACE DELETE DIV CODE HERE
  });

  $("#myContainer").on("dblclick", "#MyFirstDiv", function(e) {
    e.preventDefault();
    $(".draggable").draggable('disable');

    this.querySelector(":scope > :first-child").focus();

  });

  $("#myContainer").on("blur", "#MyFirstDiv", function(e) {
    e.preventDefault();
    $(".draggable").draggable('enable');
  });

});

#myContainer {
  border: 1px solid black;
  height: 400px;
  width: 100%;
}

#DraggableDiv {
  border: 1px solid blue;
}

Answer №1

Simple method for detecting when the delete key is pressed.

$('#AnotherDiv').click(function(e){
   e.preventDefault(); 
});
$('#AnotherDiv').keydown(function(e){
    e.preventDefault();
    if(e.keyCode == 46) {
        this.remove();
    }
});

Answer №2

To begin, start by creating a variable called divClicked to store the clicked state of the div.

var divClicked = false;

Next, in your event listener, toggle the value of divClicked when the div is clicked:

$("#MyFirstDiv").click(function(e) {
    e.preventDefault();
    divClicked = !divClicked;
}

Lastly, include a keydown event listener for the delete key:

$("#MyFirstDiv").keydown(function(e) {
    e.preventDefault();
    if (e.keyCode == 46) {
        if (divClicked) {
            $(this).remove();
        } else {
            alert("Please click the div first and then press Delete to remove it.");
        }
    }
})

Here is the complete code:

var divClicked = false;

$("#MyFirstDiv").click(function(e) {
    e.preventDefault();
    divClicked = !divClicked;
}

$("#MyFirstDiv").keydown(function(e) {
    e.preventDefault();
    if (e.keyCode == 46) {
        if (divClicked) {
            $(this).remove();
        } else {
            alert("Please click the div first and then press Delete to remove it.");
        }
    }
})

Using the Delete function while editing content is not recommended. It's important to allow users to click on the <div> element itself without triggering content editing.

Since the <div> is draggable, it would be best to use a handle to prevent the click and keypress events from conflicting with content editing and your script.

$(function() {
  // JavaScript functions for enabling/disabling dragging 
});

#myContainer {
  // CSS styles
}

<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.min.js"></script>

<div id="myContainer">
  <div class="draggable ui-widget" id="DraggableDiv">
    // HTML structure
  </div>
</div>

This <div> element is draggable, resizable, and editable. Users can disable dragging by clicking the lock icon. If they choose to delete the item by selecting the div and clicking "Delete" or pressing key code 46, a confirmation prompt will appear before removing the item.

To handle both ways of triggering deletion, I implemented a delete function.

In more complex UI interactions, simple HTML structures like this may not suffice. It's advisable to create specific targets for different events (edit, select, drag) to better manage event scripting.

Select text by clicking on it.
To delete, press the D key. [unfortunately, the delete key does not work on Stack Overflow. You can change the key code in the if statement to DELETE]

Explanation

Two functions are used to address this issue.
Select: This function selects the clicked div.
EventListener: Listens for keypress events and deletes the selected div.

Select function

The global variable "selected" stores information about the selected div.
In the select function, the ID of the clicked div is retrieved using currentTarget.id from the event object 'e'.
The select function contains if statements to select and deselect the div.

EventListener

Uses the event object from the keypress listener to determine the pressed key.
e.keyCode retrieves the key, while e.which serves as a fallback for IE users.
If the keyCode is 100 (corresponding to the D key), the selected variable is used to access the selected div and hide it by changing its CSS display property to 'none'.

An else statement allows additional JavaScript to be added when no div is selected but a key is pressed. The CSS class "selected" provides visual feedback when a div is selected.

Below is the code snippet:

let selected;

const select = e => {
    // If already selected, deselect the div
    if(selected == e.currentTarget.id) {
      document.getElementById(selected).classList.remove('selected'); // some CSS
      selected = null;
    } else {
       // Select this div
      selected = e.currentTarget.id;
      document.getElementById(selected).classList.add('selected'); // some CSS
    }
}

window.addEventListener('keypress', e => {
  // Get the key pressed
  let key = e.keyCode || e.which;
  if(selected != undefined) {
      if(key == 100) {// If D is pressed
        let target = document.getElementById(selected); // get the div
        target.style.display = 'none'; // hide the div
        console.log('deleted: ' + selected);
      }
  } else {
    // Runs if nothing is selected. Add your own logic here.
  }
})

.selected {
  background: black;
  color: white;
}

#DraggableDiv {
  user-select: none;
  cursor: pointer;
  font-family: sans-serif;
  width: 400px;
  text-align: center;
  padding: 10px 5px;
