    Somewhat new to JavaScript, hopefully this is simple.


    Ultimately what I am after is after the item is selected in a ComboBox we run an "Query" back to the server and return data to the page and fill in some text boxs (well some componentone maskedits in this case).


    I have narrowed it down to the "OnClientBlur" and "OnClientTextChanged" functions, but I have no idea on how to access the value the "ComboBox1" value/text/selectedindex.


     The only thing I have been able to figure out is if I do:


    document.getElementById("ct100_ContentPlaceHolder1_TextBox1").value = "xyz";


     I can fill in a text box with "xyz".


    I just need the "how" to get the information out of the combobox1 ...then I will work on the ajax part of the script. 


    Can anyone give me a good place to start learning javascript as well?


     Thank you for your help.

     P.S.:For learning javascript, I think you could go to this site to see if there is something you need. For ajax, you could have a look at Manning,.ASP.dot.NET.AJAX.in.Action.
