脚本如下：
        web_edit_field("tbx_channel",
                "Snapshot=t5.inf",
                DESCRIPTION,
                "Type=text",
                "Name=tbx_channel",
                ACTION,
                "FireEvent=onclick",
                LAST);


        web_edit_field("tbx_channel_2",
                "Snapshot=t6.inf",
                DESCRIPTION,
                "Type=text",
                "Name=tbx_channel",
                ACTION,
                "SetValue=北京房产",
                LAST);
但回放后报如下的错，各位有没有解决办法呢？一起出来分享一下吧！
