  • improving accessibility for the visually impaired

    Hello Everyone!Smile

    Before we start I'm a javascipt newbie as well as trying to get javascipt to work with the C# code behind page in ASP,NET.  C# alone I can do fairly

     well with however. 

    I'll just use google as an example here since it is well known.

    Here is a script (below) for allowing people to place a google search box on their page.  I plan to show a much larger duplication of it when there is a

    mouse over event (or any acceptable code-behind C# event). The asp:button (the new bigger search button) would send the search words off to google

    as though they clicked the original small button that google uses  I would need to send google the search words contained in this larger asp:TextBox

    where the query was actually typed into and save their search string in a C# code behind string for further use.  Dealing with returned search page

    results is not a problem.

    Also on the line: <input type="hidden" name="hl" value="en"></input>
    I'm assumiing all ads will be sent in English, or does google change this dynamically based on browser settings?  If not is there any practical way

    to change this based on browser settings? 

    Also, if anyone is curious, I am trying to develop web sites (and new controls for others) for disabled individals

    (right now: visually impaired, but not blind).  Any help I would greatly appreciate it.

    Here is the code:

    <center>
    <form method="get" action="http://www.google.com/custom" target="_top">
    <table bgcolor="#ffffff">
    <tr><td nowrap="nowrap" valign="top" align="left" height="32">
    <a href="http://www.google.com/">
    <img src="http://www.google.com/logos/Logo_25wht.gif" border="0" alt="Google" align="middle"></img></a>
    <label for="sbi" style="display: none">Enter your search terms</label>
    <input type="text" name="q" size="31" maxlength="255" value="" id="sbi"></input>
    <label for="sbb" style="display: none">Submit search form</label>
    <input type="submit" name="sa" value="Search" id="sbb"></input>
    <input type="hidden" name="client" value="ClientIdentifierStringRemoved"></input>
    <input type="hidden" name="forid" value="1"></input>
    <input type="hidden" name="channel" value="ClientIndentifierStringRemoved"></input>
    <input type="hidden" name="ie" value="ISO-8859-1"></input>
    <input type="hidden" name="oe" value="ISO-8859-1"></input>
    <input type="hidden" name="cof" value="GALT:#FFFFFF;GL:1;DIV:#FFFFFF;VLC:FFFFFF;AH:center;BGC:FFFFFF;LBGC:FFFFFF;ALC:FFFFFF;LC:FFFFFF;T:FFFFFF;GFNT:

            FFFFFF;GIMP:FFFFFF;FORID:1"></input>
    <input type="hidden" name="hl" value="en"></input>
    </td></tr></table>
    </form>
    </center>

    Josh,

     Thanks for the good links.  I also must admit I'm doing this because of my own bad eye sight and I know there are others who need visual help in using a computer as well.  If there is anybody out there who knows the answer to my question about making a google toolbar more visually accessible please let me know or do what Josh did and point me in some good directions.  I really appreciate everyones help on this forum and I hope it isn't too long before I can be the one answering some of the questions.

     

                                                                                Bob

    Well, your best bet would be to use Google's API rather than trying to spoof a request.  http://code.google.com/apis/ajaxsearch/

     

    Hope that helps, Paul
