HTML DOM console.groupCollapsed() Method


The HTML DOM console.groupCollapsed() method specifies the beginning of a collapsed message group.

Syntax

Following is the syntax −

console.groupCollapsed(label)

Here, label is the label for the group.

Example

Let us look at an example for the console.groupCollapsed() method −

<!DOCTYPE html>
<html>
<body>
<h1>console.groupCollapsed() Method</h1>
<p>Press F12 key to view the message in the console view.</p>
<button type="button" onclick="normMessage>NORMAL</button>
<button type="button" onclick="CollMessage()">COLLAPSED</button>
<script>
   function normMessage(){
      console.log("Hello world!");
   }
   function CollMessage(){
      console.groupCollapsed();
      console.log("This message will be inside a collapsed group!");
      console.log("This message will also be inside a collapsed group!");
   }
</script>
</body>
</html>

Output

This will produce the following output −

On clicking the NORMAL button and looking at the console view in developer options −

On clicking the COLLAPSED button and looking at the console view in developer options −

On clicking the COLLAPSED button and looking at the console view in developer options −

In the above example −

We have created two buttons COLLAPSED and GROUP that will execute the CollMessage() and groupMessage() method upon being clicked by the user.

<button type="button" onclick="normMessage()">NORMAL</button>
<button type="button" onclick="CollMessage()">COLLAPSED</button>

The normMessage() method has the console.log() method that takes in a string or object that is supplied as a parameter and simply displays it to the console.

function normMessage(){
   console.log("Hello world!");
}

The CollMessage() method has the console.groupCollapsed() method inside it that states that all of the messages that are written after this point will be displayed inside a collapsed message group. The messages are now collapsed inside the message group unlike the default extended view of the group() method −

function CollMessage(){
   console.groupCollapsed();
   console.log("This message will be inside a collapsed group!");
   console.log("This message will also be inside a collapsed group!");
}
