Description:

The element ID selector selects a single element with the given id attribute.

Syntax:

Here is the simple syntax to use this selector:

 $('#elementid')

Parameters:

Here is the description of all the parameters used by this selector:

  • elementid: This would be an element ID. If the id contains any special characters like periods or colons you have to escape those characters with backslashes.

Like any other jQuery selector, this selector also returns an array filled with the found element.

   $(document).ready(function() {
      /* This would select second division only*/
      $("#div2").css("background-color", "yellow");
   });

</script>
