IE Syntax: <br/> var myobject = document. getelementbyid ("Header"); <br/> var mystyle = myobject. currentstyle. backgroundcolor; <br/> Firefox Syntax: <br/> var myobject = document. getelementbyid ("Header"); <br/> var mycomputedstyle = document. defaultview. getcomputedstyle (myobject, null); <br/> var mystyle = mycomputedstyle. backgroundcolor; 

3. class attributes

IE Syntax: <br/> var myobject = document. getelementbyid ("Header"); <br/> var myattribute = myobject. getattribute ("classname"); <br/> Firefox Syntax: <br/> var myobject = document. getelementbyid ("Header"); <br/> var myattribute = myobject. getattribute ("class "); 

4. Obtain the "for" attribute of the label.

IE Syntax: <br/> var myobject = document. getelementbyid ("mylabel"); <br/> var myattribute = myobject. getattribute ("htmlfor"); <br/> Firefox Syntax: <br/> var myobject = document. getelementbyid ("mylabel"); <br/> var myattribute = myobject. getattribute (""); 

5. Obtain the cursor position

IE Syntax: <br/> var mycursorposition = [0, 0]; <br/> mycursorposition [0] = event. clientx; <br/> mycursorposition [1] = event. clienty; <br/> Firefox Syntax: <br/> var mycursorposition = [0, 0]; <br/> mycursorposition [0] = event. pagex; <br/> mycursorposition [1] = event. pagey; 

6. Obtain the size of the window or browser window.

IE Syntax: <br/> var mybrowsersize = [0, 0]; <br/> mybrowsersize [0] = document.doc umentelement. clientwidth; <br/> mybrowsersize [1] = document.doc umentelement. clientheight; <br/> Firefox Syntax: <br/> var mybrowsersize = [0, 0]; <br/> mybrowsersize [0] = Window. innerwidth; <br/> mybrowsersize [1] = Window. innerheight;
