Prevent HTML Link from being accessed again after being clicked

My goal is to prevent a link from submitting my form multiple times when clicked. I need this to avoid duplicate requests being sent by the same user. Below is the code I've tried, but unfortunately, it does not seem to be effective.

<a id="submit-form-link" onclick="document.forms[0].submit()" class="next">Next <span>Step</span></a>

<script type="text/javascript">
    $('#submit-form-link').click(function(){
        $('submit-form-link', this).attr('style', 'pointer-events: none;');
    });
</script>

I'm getting close to making it work, but it still seems to have some issues.

Answer №1

You should reconsider your approach. Instead of using an inline onclick event handler, try incorporating the following code within a document ready call:

$('#submit-form-link').one('click', function(){
    $('form').submit();
});

By doing this, you are binding the click event to your link and unbinding it after the first click.

An illustration of this can be seen in the console in this jsFiddle example. The form submission will only be attempted on the first click of the link, not on subsequent clicks.

Answer №2

Give this a shot:

...
$('submit-form-link').unbind().click(function() { return false; });
...

Answer №3

<a id="submit-form-link" onclick="document.forms[0].submit()" class="next">Proceed to <span>Next Phase</span></a>

<script type="text/javascript">
    $('#submit-form-link').click(function(){
        if (!$(this).hasClass('disabled')) {
            $('submit-form-link', this).attr('class', 'next disabled');
            return true;
        }
        return false;
    });
</script>

To indicate that the button is disabled, you can design a custom disabled class and apply it after clicking the button. By returning false when the button has already been clicked, you prevent any further action from taking place.

Answer №4

rebind the click event within the original click event callback function

$('#submit-form-link').click(function(){
    $('submit-form-link', this).attr('style', 'pointer-events: none;');

     $(this).click(function(e){e.preventDefault})
});

Answer №5

The onclick attribute must be removed.

$('#submit-form-link').click(function(){
    $(this).removeAttr('onclick');
});

In addition, selecting $('submit-form-link', this) is completely incorrect. This code selects nodes of type submit-form-link that are children of this. To correct this, you should use #submit-form-link and remember that this refers to the link node you just clicked.
