Get the calculated style in the CSS element (after cascading/final style)
|
To obtain the calculated style in a CSS element (that is, the final style after cascading), browsers that support W3C can use the document.defaultView.getComputedSyle method. This method accepts two parameters. The first parameter is the element to be styled, and the second parameter is a pseudo-element string (for example: ":after". If there is none, it is set to null. This method returns a StyleSheetDeclaration object, and the final style property value is obtained through the getPropertyValue(propertyName) of the object. Note that the proprtyName here is of type wrold-world (eg background-color). In IE, the element.currentStyle[propertyName] method is used. Note that the propertyName here is of the worldWorld type (such as: backgroundColor). |
