以下是我定义的三个数组,在用ASP给它们动态赋值时,赋到schoolNameArr[0][1][0]就出错了.
我看了半天还是不知道怎回事.

var competeAreaNameArr = new Array();
var schoolBoroughArr = new Array(new Array());
var schoolNameArr = new Array(new Array(new Array()))

competeAreaNameArr[0] = '长沙市';

schoolBoroughArr[0][0] = '雨花区';

schoolNameArr[0][0][0] = '长沙市天华学校';
schoolNameArr[0][0][1] = '长沙市育英学校';


schoolBoroughArr[0][1] = '开福区';

schoolNameArr[0][1][0] = '长沙市开福区国庆小学'; //当赋值到这里就出错了

schoolBoroughArr[0][2] = '芙蓉区';

schoolNameArr[0][2] = '';

schoolBoroughArr[0][3] = '岳麓区';

schoolNameArr[0][3] = '';


competeAreaNameArr[1] = '湘潭市';

schoolBoroughArr[1] = '';

由于schoolNameArr是动态分配的大小而schoolNameArr[0][1]没有赋值

[xjdawu]

schoolNameArr[0][1] = new Array();
schoolNameArr[0][1][0] = '长沙市开福区国庆小学';
