Various methods for deactivating controls in a CSS class

Is there a way to disable all buttons within a specific class? I have attempted the following code without success:

$("input.myClass").attr('disabled', true);

This is how I am trying to implement it:

<script type="text/javascript>
        $(document).ready(function() {

            var objA = $get('<%= checkbox.ClientID %>');

            $(objA).change(function() {

                if($(this).is(':checked'))
                {  
                    $(".anotherClass").sortable('disable'); //works
                    $("input.myClass").prop('disabled', 'disabled'); //doesn't work
                }

The CSS styling for this class is straightforward:

.myClass
{
    float: left; 
    width: 140px; 
    margin-left: 4px; 
    margin-right: 4px; 
    padding-top: 20px;
    text-align: center;
}

Here is an example of the HTML structure:

<div class="myClass">
        <asp:Button ID="btn1" Text="bbb" runat="server" CausesValidation="False" CssClass="button" OnClientClick="return false;" />
        <asp:Button ID="btn2" Text="aaa" runat="server" CausesValidation="False" CssClass="button" OnClientClick="return false;" />
        <asp:Button ID="btn3" runat="server" CausesValidation="False" CssClass="button" OnClick="bt_Click" />
    </div>

Answer №1

If you are using jQuery version 1.6 or higher, it is recommended to use the .prop() function to change the disabled property.

$("input.myclass").prop('disabled', true);
$("input.myclass").prop('disabled', false);

For jQuery versions 1.5 and below, you can achieve a similar effect using the .attr() function:

Disable input field by setting the disabled attribute.

$("input.myclass").attr('disabled','disabled');

To enable the input field again:

$("input.myclass").removeAttr('disabled');

Source: Stack Overflow

Answer №2

To deactivate input fields:

$('input.myClass').attr('disabled', 'disabled');

// To activate 

$('input.myClass').removeAttr('disabled');

// Alternatively, you can set the attribute to an empty string 

$('input.myClass').attr('disabled', '');

Answer №3

To deactivate all buttons, simply utilize the following code: $("input[type='button']").attr("disabled","disabled");

Answer №4

If you are looking to utilize the attr() function, follow these steps:

$("input.myClass").attr('disabled', 'disabled');

Alternatively, you can use prop():

$("input.myClass").prop('disabled', true);

Regarding the revised query:

  1. Revise your script tag to be <script>
  2. Position it at the bottom of the page rather than in the header section

Answer №5

There are various ways to prevent default actions, but one common method is:

$('button.myButton').click(function(e){
    e.preventDefault();
})

By using the preventDefault() function, you can stop default behaviors such as form submission.

Answer №6

Make use of .prop

$("input.myClass").prop("disabled", true);

To disable all button type inputs within a div that has the class myClass:

$(".myClass input[type=button]").prop("disabled", true);

Answer №7

$(".myClass :input").prop('disabled', true);

This single line did the trick for me.
