求助 JSON问题
是这样的,服务端返回的是一个二维数组数据,在js端 我接收到数据,但是

汉字是乱码?
出输的html是错误的,循环不出数据来??

还请高手指点一下。


js:

JScript code

'; var i,size,result; url='stock.php'; $.post(url, function(data){ result = eval('(' + data + ')'); size = result.length; for (i = 1; i "; } }); html+='
" + result[i][1] + " " + result[i][2]+ " " + result[i][3] + "
'; alert(html);




服务端:
