varmyArray=newArray（5）;
4:
myArray[0]=“FirstEntry”;
5:

8:
//-->
9:
</script>25在页面卸载时候执行函数1:
<bodyonUnload=”functionName（）;”>
2:
Bodyofthepage
3:
</body>javascript就这么回事2：

7:
varpairValue=pairParts[1];
8:
document.write（pairName+“：
“+pairValue）;
9:
}
10:
</script>你还以为HTML是无状态的么？
33打开一个新的document对象1:
