Last Updated : 30 Nov, 2020

The script.aculo.us library is a cross-browser library that aims at improving the user interface of a website. The Ajax.InPlaceEditor is used to make elements editable thereby allowing the user to edit the content on the page and submit the changes to the server.

The InPlaceEditor cols option is used to specify the number of columns to be shown in the InPlaceEditor. This property works for both single and multiline area input.

Syntax:

{ cols: value }

Parameters: This option has a single value as mentioned above and described below:

value: This is a number that is used to specify the number of columns to be shown in the editor.

The below example illustrates the use of this option.

Example:

The below script is required to simulate the saving of data to the server.

PHP

<?php 
  if( isset($_REQUEST["value"]) ) { 
    $str = $_REQUEST["value"]; 
    echo $str; 
  } 
?>

The below script demonstrates this with the example:

    window.onload = function () { 
  
      // Default InplaceEditor with no 
      // options 
      new Ajax.InPlaceEditor( 
        'editableElement', 
        'http://localhost/tmpscripts/inplace.php', 
      ); 
  
      // InplaceEditor with the cols 
      // option changed to a custom value 
      new Ajax.InPlaceEditor( 
        'editableElement2', 
        'http://localhost/tmpscripts/inplace.php', 
        { 
  
          // Specify the number of columns 
          // to be used in the InplaceEditor
