Answer №1

To dynamically toggle the disabled state of a button based on the checkbox status, you can use the following code:

$('#agree').on('change', function() {
  $('button').prop('disabled', !this.checked);
});

If there are multiple buttons on the page and you want to target the next button after the #agree checkbox specifically, you can do so by traversing the DOM:

$('~ div:first', this).find('button').prop('disabled', !this.checked);

The expression $('~ div:first', this) selects the first div element that appears after the current element (#agree).

Although you may be looking for a JavaScript solution, I wanted to share an alternative method using only CSS.

It's important to note that avoiding the use of the font tag and transferring your CSS to an external stylesheet is considered best practice.

Here is the HTML code:

<input id="agree" type="checkbox" name="agree">I agree to the terms of service...
<div>
    <button>Register</button>
    <div></div>
</div>

And here is the corresponding CSS:

div {
    position:relative;
    text-align:center;
}
div div {
    height:100%;
    position:absolute;
    top:0;
    left:0;
    width:100%;
}
button {
    background:grey;
    color:#c0c0c0;
}
input[type=checkbox]:checked + div div {
    display:none;
}
input[type=checkbox]:checked + div button {
    background:#c0c0c0;
    color:black;
}
