How to disable button using jquery in materialize css

问题

I am using jquery to disable a button in materialize css. According to documentation here, the way to disable button is simply by adding a class named 'disabled'.I think by simply add class 'disabled', the button will automatically disabled, but it is not. Here is my code:

html:

<button id='submit-btn' class="btn waves-effect waves-light submit red" type="button" name="action">

jquery:

$('#submit-btn').off().on('click', function(){
    $('#submit-btn').addClass('disabled');
});

回答1:

Try this

$('#submit-btn').removeClass("waves-effect waves-light submit").addClass('disabled');

Working Demo

$(document).ready(function() {
  $('#submit-btn').on('click', function() {
    $(this).removeClass("waves-effect waves-light submit").addClass('disabled');
  });
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

<button id='submit-btn' class="btn waves-effect waves-light submit red" type="button" name="action">

What about

$('#submit-btn').prop('disabled', true).addClass('disabled');

回答3:

to disable button you can use

$("#submit-btn").attr("disabled", "true");

回答4:

Create a variable which holds the button (say submitBtn), then add an event listener (say on DOMContentLoaded), then have the function disable the button with submitBtn.disabled = true;
