关于 for 语句的问题
var a = new Array();
function CX(){
this.GetA = function(){
return "cc ";
}
}
a.push(new CX());
a.push(new CX());
a.push(new CX());
for( b in a){
alert( b.GetA() );
}
好像这样不行？
for in 这种语句不支持对象数组么？
如果我一定要用 for in 的写法，应该怎样做呢？
thx thx
[解决办法]
var a = new Array();
function CX(){
this.GetA = function(){
return "cc ";
}
}
a.push(new CX());
a.push(new CX());
a.push(new CX());
var b = new CX();
for( b in a){
alert( a[b].GetA() );
}
[解决办法]
var a = new Array();
function CX(){
this.GetA = function(){
return "cc ";
}
}
a.push(new CX());
a.push(new CX());
a.push(new CX());
for( b in a){
alert(eval( "a[ "+b+ "].GetA(); "));
}

楼主你那个b没有声明吧
[解决办法]
foreach （b in a）
[解决办法]
<script language= "javascript ">
function CX(){
this.GetA = function(){
return "cc ";
}
}
function aa()
{
debugger
var a = new Array();
a.push(new CX());
a.push(new CX());
a.push(new CX());
for(var b in a)//将执行循环0到a.length-1
{
alert( a[b].GetA() );//此时b是a的本次循环的索引值
}
}
</script>
[解决办法]
这里的b是a的一个下标
就要用a[b]来获取a中的一个对象
当然你不var b的话，b就是全局的了
