js,split可使冒号，分号变逗号?

还有 if (mData2[j][0].indexOf(checkStr) != -1) 这句是要判断什么的呢？

split是把字符串分割成数组如 a = "abc;def;ghi" b = a.split(";") 把a字符串用;分割成数组 b的值就是 ["abc","def","ghi"] 这样一个数组在用alert输出数组时，会自动调用数组对象的toString方法把数组转换成字符串，数组对象的toString方法类似于调用 join(",") 就是把数组的各元素用“,”拼接成字符串

split分割成数组后在alert其实是调了数组的toString方法 toString默认吧,作为分割符你不要alert 用console.log就看出来是数组了
