请帮助我在.ascx网络用户控件中了解此脚本

Question

The following is found within a .ascx web user control, and I'm trying to figure out where I would find "localtable_" and what the last line is doing.

<script language="javascript" type="text/javascript">
    function ClickTable(me)
    {
        var tables = document.getElementsByTagName("table");
            for(n = 0; n < tables.length; n++)
                if(tables[n].id.indexOf("localtable_") > -1)
                    tables[n].className = "";
        me.className = "CommitteeTableBackground";
    }
</script>

Answer 1

Try view source of the Page from the Browser where the user control is used. It should give you all the tables starting with localtable_ Ids.

1. The script is setting the class names of all tables with Ids that start with "localtable_" to empty.
2. Setting the current table class name to CommitteeTableBackground. May be this done to highlight only the currently selected class.
