Disabled button still listens to click event

Question

I have a problem in a form where I do some jquery validations. If a specific input field is not filled out, it should disable a \"step forward\" button by adding a disabled attr

Answer 1

use pointer-events:none; where you don't needed click events

.btn[disabled]{pointer-events:none;}

document.querySelectorAll(".btn").forEach(btn=>{
    btn.addEventListener("click", e=>{
      alert(e.target.innerText)
    })
})

.btn{
  display:inline-block;
  background: #3f51b5;
  color: #fff;
  box-shadow: 0 2px 2px 0 rgba(0,0,0,.14),
   0 3px 1px -2px rgba(0,0,0,.2),
   0 1px 5px 0 rgba(0,0,0,.12);
    border: none;
    border-radius: 2px;
    position: relative;
    height: 36px;
    margin: 10px;
    min-width: 64px;
    padding: 0 16px;
    display: inline-block;
    font-family: "Roboto","Helvetica","Arial",sans-serif;
    font-size: 14px;
    font-weight: 500;
    text-transform: uppercase;
    letter-spacing: 0;
    overflow: hidden;
    will-change: box-shadow;
    transition: box-shadow .2s cubic-bezier(.4,0,1,1),background-color .2s cubic-bezier(.4,0,.2,1),color .2s cubic-bezier(.4,0,.2,1);
    outline: none;
    cursor: pointer;
    text-decoration: none;
    text-align: center;
    line-height: 36px;
    vertical-align: middle;   
}

.btn[disabled]{pointer-events:none; opacity:0.5}

Clickable button
Clickable 2 button
Clickable 3 button

Disabled button
Disabled 2 button
