Prevent the insertion of HTML elements into the DIV using jQuery

Question

Prevent the insertion of HTML elements into the DIV using jQuery

Check out this code snippet:

<div id="whatever">
/* Setting up a button to add HTML code in this div using jQuery */
/* Now looking to create another button that will prevent further additions to the div with the existing HTML intact */
</div>

Is there a way to achieve this without using jQuery, maybe with CSS? I tried the following:

$(".whatever").attr("disabled", "disabled");
$(".whatever").prop("disabled", "disabled");

After some research, I discovered that only form elements have a disabled attribute.

In my opinion, utilizing this method provides a more streamlined approach compared to manually inserting and deleting attributes.

$("section *").deactivate();

Disabled state is not inherent in 'div' elements. A workaround is to use a boolean variable like 'isEditable' in Javascript and toggle its state. Here's an example:

Check out the JS Fiddle demo: http://jsfiddle.net/weM57/

<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.0/jquery.min.js"></script>
<script type='text/javascript'>

$(document).ready(function() {

    var isEditable = true;

    $("#btnAdd").click(function() { 
        if (isEditable) {
            $("#whatever").append("<p>this is some content</p>");
        } else {
            $("#status").html("<p>The div is not editable at the moment</p>");
        }   
    });

    $("#btnDisable").click(function() { 
        isEditable = false;
        $("#status").html("<p>The div is not editable anymore</p>");
    });

    $("#btnEnable").click(function() {  
        isEditable = true;
        $("#status").html("<p>The div is editable now</p>");
    });

});

</script>
</head>
<body>

    <input type="button" id="btnAdd" value="Add Content" />

    <hr />

    <input type="button" id="btnDisable" value="Disable Content Adding" />
    <input type="button" id="btnEnable" value="Enable Content Adding" />

    <hr />

    <div id="whatever">

    </div>

    <div id="status" style="border: dotted 1px gray; background-color: yellow; padding: 20px;">
    </div>
</body>

Answer №3

When you click the button to disable a div, you can add a specific class to that div, such as disabled. Then, in your code, check for the presence of this class and avoid adding anything if it is present.

You can implement this logic using the following script:

$('.addButton').click(function(){ 
   if ($('#whatever').hasClass('disabled'))
      return false;
   // Insert your code here
});

$('.disableButton').click(function(){
    $('#whatever').addClass('disabled')
});

To see this concept in action, refer to this working example on FIDDLE.

By clicking "add html," new content is appended to the div. Clicking "disable" will prevent further additions to the div by disabling it. An "enable" button is also included to demonstrate how you can re-enable the div if needed.
