I have some Javascript and ASP in a webpage. How do I pass a Javascript variable to ASP (read below)?

Essentially I have a variable named "strfile" that is in Javascript. I need to access this variable or "make it available to be used" by ASP. The Javascript and ASP code is all in the same page.

The easiest way is to set the value of the JavaScript variable to a hidden input field.





%26lt;input type="hidden" name="strfile" id="strfile" /%26gt;





Then in your JavaScript, simply say:





document.getElementById ('strfile').value = strfile;





When you submit the form, the page that receives the submit action (could be the same or a different page), the strfile variable will be available in ASP as request.form("strfile")
Reply:Maybe this could give you a hint.





To get the whole query string:





%26lt;%


the_name = Request.QueryString() ' Your var value


%%26gt;


%26lt;script language="javascript"%26gt;


var the_name = ""


%26lt;/script%26gt;


%26lt;%


Dim the_name


the_name = Request.QueryString()


Response.write("the name is " %26amp; the_name)


Response.write("%26lt;script%26gt;the_name=""" %26amp; the_name %26amp; """;%26lt;/script%26gt;")


%%26gt;


%26lt;script language="javascript"%26gt;


alert(the_name)


%26lt;/script%26gt;





Hope this helps.
