How to disable/enable a button with a checkbox if checked [duplicate]

Please i need a script that can work with the HTML code bellow to disable/enable the button when a checkbox is checked or unchecked,

<input type="submit" name="sendNewSms" class="inputButton" id="sendNewSms" value=" Send " />

please pals i don't mean the button to be disabled when checked, but rather the other way round.

Solution 1:

You can use onchangeevent of the checkbox to enable/disable button based on checked value

<input type="submit" name="sendNewSms" class="inputButton" id="sendNewSms" value=" Send " />

<input type="checkbox"  onchange="document.getElementById('sendNewSms').disabled = !this.checked;" />

Solution 2:

HTML

<input type="checkbox" id="checkme"/><input type="submit" name="sendNewSms" class="inputButton" id="sendNewSms" value=" Send " />

JS

var checker = document.getElementById('checkme');
var sendbtn = document.getElementById('sendNewSms');
checker.onchange = function() {
  sendbtn.disabled = !!this.checked;
};

Solution 3:

You will have to use javascript, or the JQuery framework to do that. her is an example using Jquery

   $('#toggle').click(function () {
        //check if checkbox is checked
        if ($(this).is(':checked')) {

            $('#sendNewSms').removeAttr('disabled'); //enable input

        } else {
            $('#sendNewSms').attr('disabled', true); //disable input
        }
    });

Here is a clean way to disable and enable submit button:

<input type="submit" name="sendNewSms" class="inputButton" id="sendNewSms" value=" Send " />
<input type="checkbox" id="disableBtn" />

var submit = document.getElementById('sendNewSms'),
    checkbox = document.getElementById('disableBtn'),
    disableSubmit = function(e) {
        submit.disabled = this.checked
    };

checkbox.addEventListener('change', disableSubmit);
