1. element. style:Only the style values written in the style attribute in the element label can be obtained.And pass Loaded style attributes

The Code is as follows:

Var ele = document. getElementById ('ele ');
Ele. style. color; // obtain the color.

2. window. getComputedStyle ():You can obtain all final CSS attribute values of the current element.

The Code is as follows:

Window. getComputedStyle ("element", "pseudo class ");

This method accepts two parameters: the element to obtain the calculated style and a pseudo element string (for example, ": before "). If the pseudo element information is not required, the second parameter can be null. You can also use document. defaultView. getComputedStyle ("element", "pseudo class ");

The Code is as follows:

Var ele = document. getElementById ('ele ');
Var styles = window. getComputedStyle (ele, null );
Styles. color; // obtain the color.

You can use style. length to view the number of default styles in the browser. The IE6-8 does not support this method and requires the following method. For Firefox and Safari, the color is converted to rgb format.

3. element. currentStyle:The returned result is the final CSS attribute value of the current element application (including the external link CSS file, embedded in the page ).
