Question

I’m using jquery $.post when submitting a form. I want to disable the button for like 5 seconds after it has been clicked to avoid multiple submission of the form.

here’s what I’ve done for now:

$('#btn').click(function(){
    $.post(base_url + 'folder/controller/function',$('#formID').serialize(),function(data){
        $('#message').slideDown().html('<span>'+data+'</span>');
    });
});

I’ve used fadeIn and fadeOut before, but still it doesn’t work when I tested it clicking the button rapidly. What should I do to achieve what I wanted to happen?

Answer 1

You can do what you wanted like this:

var fewSeconds = 5;
$('#btn').click(function(){
    // Ajax request
    var btn = $(this);
    btn.prop('disabled', true);
    setTimeout(function(){
        btn.prop('disabled', false);
    }, fewSeconds*1000);
});

or you can use jQuery’s .complete() method which is being executed after the ajax receives a response:

$('#btn').click(function(){
    var btn = $(this);
    $.post(/*...*/).complete(function(){
        btn.prop('disabled', false);
    });
    btn.prop('disabled', true);

});

edit: this is an example with 3 seconds server-side response delay

Edit

Since even the answer is 8 years old, but still getting attention and jQuery is getting less popular I think it’s worth adding example without jQuery

const fewSeconds = 3
 
document.querySelector('#btn').addEventListener('click', (e) => {
    e.target.disabled = true
  setTimeout(() => {
   e.target.disabled = false
  }, fewSeconds * 1000)
})

<input type='button' id="btn" value="click me" />
