Cara menggunakan remove target attribute javascript

setAttribute(name, value)

name

A string specifying the name of the attribute whose value is to be set. The attribute name is automatically converted to all lower-case when setAttribute() is called on an HTML element in an HTML document.

A string containing the value to assign to the attribute. Any non-string value specified is converted automatically into a string.

Boolean attributes are considered to be true if they're present on the element at all. You should set value to the empty string (

<button>Hello World</button>

Since the specified value gets converted into a string, specifying

<button>Hello World</button>

<button>Hello World</button>

<button>Hello World</button>

None (

<button>Hello World</button>

<button>Hello World</button>

<button>Hello World</button>

The specified attribute name contains one or more characters which are not valid in attribute names.

In the following example, setAttribute() is used to set attributes on a

button {
  height: 30px;
  width: 100px;
  margin: 1em;
}

<button>Hello World</button>

button {
  height: 30px;
  width: 100px;
  margin: 1em;
}

const button = document.querySelector("button");

button.setAttribute("name", "helloButton");
button.setAttribute("disabled", "");

This demonstrates two things:

• The first call to setAttribute() above shows changing the name attribute's value to "helloButton". You can see this using your browser's page inspector (Chrome, Edge, Firefox, Safari).
• To set the value of a Boolean attribute, such as

  button {
    height: 30px;
    width: 100px;
    margin: 1em;
  }
  

  5, you can specify any value. An empty string or the name of the attribute are recommended values. All that matters is that if the attribute is present at all, regardless of its actual value, its value is considered to be true. The absence of the attribute means its value is

  button {
    height: 30px;
    width: 100px;
    margin: 1em;
  }
  

  7. By setting the value of the

  button {
    height: 30px;
    width: 100px;
    margin: 1em;
  }
  

  5 attribute to the empty string (

  <button>Hello World</button>
  

  1), we are setting

  button {
    height: 30px;
    width: 100px;
    margin: 1em;
  }
  

  5 to true, which results in the button being disabled.

DOM methods dealing with element's attributes:

const button = document.querySelector("button");

button.setAttribute("name", "helloButton");
button.setAttribute("disabled", "");

const button = document.querySelector("button");

button.setAttribute("name", "helloButton");
button.setAttribute("disabled", "");

const button = document.querySelector("button");

button.setAttribute("name", "helloButton");
button.setAttribute("disabled", "");

const button = document.querySelector("button");

button.setAttribute("name", "helloButton");
button.setAttribute("disabled", "");

const button = document.querySelector("button");

button.setAttribute("name", "helloButton");
button.setAttribute("disabled", "");

const button = document.querySelector("button");

button.setAttribute("name", "helloButton");
button.setAttribute("disabled", "");

const button = document.querySelector("button");

button.setAttribute("name", "helloButton");
button.setAttribute("disabled", "");

const button = document.querySelector("button");

button.setAttribute("name", "helloButton");
button.setAttribute("disabled", "");

Using setAttribute() to modify certain attributes, most notably value in XUL, works inconsistently, as the attribute specifies the default value. To access or modify the current values, you should use the properties. For example, use getAttribute()9 instead of removeAttribute()0.
