1.在改变单个元素样式时,注意style对象的语法和css中使用的语法几乎是一一对应的。不过包含连字符的属性则被替换为一种“camel castring”的形式,例如:font-size现在成了fontSize,而margin-top变成了marginTop; 2.在使用“float”时,因为“float”是javascript的一个保留字,所以就不能使用style.float,而改成了style.cssFloat(IE使用的是style.styleFloat); 3. 获得元素的计算样式: 在W3C DOM下可以: 复制代码 代码如下: 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标准方法,可以: 复制代码 代码如下: var heading = document.getElementById("heading"); var computedFontFamily = heading.currentStyle.fontFamily;//sans-serif 综合上述这些方法,可以创建一个跨浏览器函数来实现 复制代码 代码如下: 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]; } 对照表

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.
