1.在改變單個元素樣式時，注意style對象的語法和css中使用的語法幾乎是一一對應的。不過包含連字符的屬性則被替換為一種“camel castring”的形式，例如：font-size現在成了fontSize，而margin-top變成了marginTop；
2.在使用“float”時，因為“float”是javascript的一個保留字，所以就不能使用style.float，而改成了style.cssFloat(IE使用的是style.styleFloat)；
3. 獲得元素的計算樣式:
在W3C DOM下可以：
復制代碼 代碼如下:
var heading = document.getElementById("heading");
var computedStyle = document.defaultView.getComputedStyle(heading,null);
var computedFontFamily = computedStyle.fontFamily;//sans-serif
IE不支持使用DOM標准方法，可以：
復制代碼 代碼如下:
var heading = document.getElementById("heading");
var computedFontFamily = heading.currentStyle.fontFamily;//sans-serif
綜合上述這些方法，可以創建一個跨浏覽器函數來實現
復制代碼 代碼如下:
function retrieveComputedStyle(element,styleProperty){
var computedStyle = null;
if(typeof element.currentStyle != "undefined"){
computedStyle = element.currentStyle;
}else{
computedStyle = document.defaultView.getComputedStyle(element,null);
}
return computedStyle[styleProperty];
}

Usage
Internet Explorer
document.all.div_id.style.JS_property_reference = "new_CSS_property_value";
Older Netscape's (4.7 and earlier)
document.div_id.JS_property_reference = "new_CSS_property_value";
Netscape 6.0+ and Opera (and other Mozilla)
document.getElementById(div_id).style.JS_property_reference = "new_CSS_property_value";
Note the use of parentheses instead of square brackets in newer Mozilla's "getElementById()" reference.
