Prototype - getStyle() Method


Advertisements


This method returns the given CSS property value of element. Property can be specified in either of its CSS or camelized form.

Thus providing font-size and fontSize are equivalent.

Syntax

element.getStyle( property );

Return Value

Either CSS property value or NULL if it does not find a property set. Internet Explorer returns literal values while other browsers return computed values. Safari returns null for any non-inline property if the element is hidden.

Example

<html>
   <head>
      <title>Prototype examples</title>
      <script type = "text/javascript" src = "/javascript/prototype.js"></script>
      
      <script>
         function showResult() {
            var str = $('grandfather').getStyle('margin-left');
            alert("Element left margin is : " + str );
         }
      </script>
      
      <style>
         #grandfather {
            font-size: 12px;
            margin-left: 1em;
         }
      </style>
   </head>
   
   <body>
      <p>Click the button to see the result.</p>
      
      <div id = "grandfather">This is grand father
         <div id = "father"> This is father.
            <div id = "kid">This is kid</div>
         </div>
