怎么循环读出数据啊?

这是网页JS代码{"czName":"双色球","kjDate":"2013-09-24","kjIssue":"2013112","kjTNum":"07","kjZNum":"31 13 12 22 01 06"}
{"czName":"双色球","kjDate":"2013-08-29","kjIssue":"2013101","kjTNum":"01","kjZNum":"05 23 32 09 27 07"}
{"czName":"双色球","kjDate":"2013-10-22","kjIssue":"2013124","kjTNum":"07","kjZNum":"09 15 30 03 25 23"}
{.................如何一次性读出 "kjIssue": 后面的值啊 也就是期号? 单个读取就会 不知道如何全部读取 新手不懂 帮帮忙!
