Question

有谁能帮我解释一下这段代码的意思么，详解，谢谢

<script>
var changeStyle = function (elem, attr, value)
{
elem.style[attr] = value
};
window.onload = function ()
{
var oBtn = document.getElementsByTagName("input");
var oDiv = document.getElementById("div1");
var oAtt = ["width","height","background","display","display"];
var oVal = ["200px","200px","red","none","block"];
for (var i = 0; i < oBtn.length; i++)
{
oBtn[i].index = i;
oBtn[i].onclick = function ()
{
this.index == oBtn.length - 1 && (oDiv.style.cssText = "");
changeStyle(oDiv, oAtt[this.index], oVal[this.index])
}
}
};
</script>
有没有人呢

这是一段javascript代码，实现的功能是当你点击 name="input"的标签的时候，改变它的样式。 var oAtt = ["width","height","background","display","display"]; var oVal = ["200px","200px","red","none","block"];这里设置了改变的具体信息，宽度和高度改变为200px，背景改变为红色
