How to disable HTML button using JavaScript?

Since this setting is not an attribute

It is an attribute.

Some attributes are defined as boolean, which means you can specify their value and leave everything else out. i.e. Instead of disabled="disabled", you include only the bold part. In HTML 4, you should include only the bold part as the full version is marked as a feature with limited support (although that is less true now then when the spec was written).

As of HTML 5, the rules have changed and now you include only the name and not the value. This makes no practical difference because the name and the value are the same.

The DOM property is also called disabled and is a boolean that takes true or false.

foo.disabled = true;

In theory you can also foo.setAttribute('disabled', 'disabled'); and foo.removeAttribute("disabled"), but I wouldn't trust this with older versions of Internet Explorer (which are notoriously buggy when it comes to setAttribute).

Javascript- How to disable a html button using javascript

Set disabled = true in javascript function

     <input type="button" class="standardbutton" value="Password Reset" id="mybutton" onclick=" passwordReset()"/>

In JS

function passwordReset(){
  document.getElementById("mybutton").disabled = true;
}

Disable and enable button by over or under age 18 Javascript

You can assign false to the disabled attribute. Also, as your code stands, you can omit the condition simply using the else block.

Demo:

var ageEl = document.getElementById('age');

manageBtn(ageEl);

ageEl.addEventListener('input', function(){manageBtn(ageEl);});

function manageBtn(el){
  var age = ageEl.value;
  if(age < 18){
    document.getElementById('age').style.borderColor='#e52213';
    document.getElementById("Btn").disabled = true;
  }
  else{
    document.getElementById('age').style.borderColor='';
    document.getElementById("Btn").disabled = false;
  }
}

<input type="number" id="age">
<button id ="Btn">My Button</button>

How do I disable and re-enable a button in with javascript?

true and false are not meant to be strings in this context.

You want the literal true and false Boolean values.

startButton.disabled = true;

startButton.disabled = false;

The reason it sort of works (disables the element) is because a non empty string is truthy. So assigning 'false' to the disabled property has the same effect of setting it to true.

How to disable submit button after click
