不知道在哪里錯(cuò)了
var arry=['1','2','3','4','5','6','7'];
arry[7]=8;
document.write("數(shù)組長(zhǎng)度："+arry.length+"
");
for(i=0;i<=7;i++)
{
? ?document.write("數(shù)組"+i"為"+arry[i]+"
");
}
哪里不對(duì)?。?/p>

var arry=['1','2','3','4','5','6','7'];?
arry[7]=8;?
document.write("數(shù)組長(zhǎng)度："+arry.length+"");
//這里
var i;?
for(i=0;i<=7;i++)?
{ ? ?document.write("數(shù)組"+i"為"+arry[i]+""); }?
