请问这里错在哪里

请问这段代码怎么无效。作用就是我从JHB0中选择品名。其他文本框自动就调出去了。规格，图号，品牌
还有一个问题就是。我能不能输入品名来自动索引。而不是选择。在我这原有基础上改
[解决办法]

// ssplit函数你没定义吧，要么就有问题。。   
 
  function redirect(x) {
        var arr = x.split(',');
        reg.guige.value = arr[0]; // ssplit(x, ",", 0);
        reg.tuhao.value = arr[1]; //ssplit(x, ",", 1);
        reg.pinpai.value = arr[2]; // ssplit(x, ",", 2);

    }
