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
------解决方案--------------------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() );
}
------解决方案--------------------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(); "));
}

------解决方案--------------------楼主你那个b没有声明吧
------解决方案--------------------foreach (b in a)
------解决方案-------------------- <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>
------解决方案--------------------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
