JavaScript 学习笔记——cssText

obj.cssText = " width:200px;position:absolute;left:100px;";

obj.cssText += " width:200px;position:absolute;left:100px;";

obj.cssText += " ;width:200px;position:absolute;left:100px;";　//这样便能解决在IE中出现的问题了

//使用JSON
function setStyle(obj,json){
    for(var i in json)
    {
        obj.style[i]=json[i];
    }
}

setStyle(obj,{width : ‘200px‘; position : ‘absolute‘; left : ‘100px‘;});
