如何改呀？我实在搞不清楚。

以上代码，我想改成
arrItems1[03] = "Truck";
arrItemsGrp1[03] = 01;
arrItems1[04] = "Train";
arrItemsGrp1[04] = 01;
arrItems1[05] = "Car";
arrItemsGrp1[05] = 01;
可是就出错了，我应如何是好呀？
是不是应先把01改为字符型，真搞不懂了.

如何在javascript数组中用字符串做下标？

数组下标必须是0~2e32-1的整数

就没有解决的方法嘛？

老大你开玩笑吧？

arrItems1['03'] = "Truck";
arrItemsGrp1['03'] = '01';
arrItems1['04'] = "Train";
arrItemsGrp1['04'] = '01';
arrItems1['05'] = "Car";
arrItemsGrp1['05'] = '01';
这样定义是合法的，你说的不行是程序调用此数组出错吧？也许你那段程序把数组索引作为整数运算的

PHP会不?数组下标可以是英文中文等的

arr=new Array();
arr['saa']='adc';
arr['o0020']='wprpwpr';
alert(arr);

看Office 某目录下的手册吧

我就是不想索引作为整数运算；
而在php中，就可以。
郁闷呀~~~~~~~~~~~~~~~~
