    <script language="JavaScript"> //this script store the value of the table
                    fm1.ivcd_item['0'].value="B747-400";
                    fm1.ivcd_totalfc['0'].value="500.00";
                    fm1.ivcd_unitprice['0'].value="1";
                    fm1.ivcd_quantity['0'].value="";

                    fm1.ivcd_item['2'].value="B747-800";
                    fm1.ivcd_totalfc['2'].value="250.00";
                    fm1.ivcd_unitprice['2'].value="";
                    fm1.ivcd_quantity['2'].value="";
     </script>          
    </FORM>

My question is, How to use C# get the value of the table, suach as 'B747-400' or 'B747-800'? My idea is use BHO(Browse Helper Object), but How to do?

You can easily parse html using tools like the HtmlAgilityPack[^].

This is not going to be easy. It is easy enough to parse the XML parsing the XML into a XDocument:

string str =
@"
<!-- comment at the root level -->
<root>
    <child>Content</child>
</root>";
XDocument doc = XDocument.Parse(str);

This will allow you to get to all the information in the xml, including the content of the script tag by using the following

C#

child = doc.Descendants("Child").FirstOrDefault();
Console.WriteLine(child.Value);

Unfortunately, still have to parse the content of the script tag. That will require you to go through and do the hard work. What I recommend is to use regular expressons. I am not an expert at working with regular experssions, and it is going to require some fancy stuff to do the extraction, but I have seen some really neat stuff with regular expressons, for instance C# Formula Evaluator using Regular Expressions (http://www.jarloo.com/c-formula-evaluator[^]). You will have to read up on regular expressons.
