0x800a1391-JavaScript 运行时错误:“admin_user_shen“未定义

<script>
function funExec() {
var selcnt = funSelectedTotal("tbInfo");
var exen = funExistNum("de", selcnt);
if (exen) {
    if (confirm("确认你的选择吗")) {
        var isok = admin_user_shen.SetMy(funGetSelectedID("tbInfo")).value;
        if (isok == "1" || isok == 1) {
            alert("恭喜你，审核成功!");
            window.location.href = "user_shen.aspx";
        }
        else {
            alert("操作失败，请稍候重试！");
        }
    }
}

}

var isok = admin_user_shen.SetMy(funGetSelectedID("tbInfo")).value;里admin_user_shen在哪里定义的
