二级联动 实在想不出哪里错了 f12提示8行少了一个分号和changeCity没有定义 但我发现并没有这个错误啊

Question

省市二级联动varcities=newArray(2);varcities[0]=newArray("安源","上栗","湘东");varcities[1]=newArray("白云","天河","越秀");functionchangeCity(val){varareaEle=document.getElementById("area");for(vari=0;i

Answer 1

cities已经定义过了，重复定义了。定义数组，在js里很简单，不用这样麻烦:
varcities=[
["安源","上栗","湘东"],
["白云","天河","越秀"]
];
                            

Answer 2

varcities[0]=newArray("安源","上栗","湘东");
varcities[1]=newArray("白云","天河","越秀");
cities数组已经定义了，这里不用var了改成
cities[0]=newArray("安源","上栗","湘东");
cities[1]=newArray("白云","天河","越秀");
