Passing Parameters

spraveens · October 8th, 2003, 02:34 AM

Hi friends !!

Iam using ASP for server side scripting and JavaScript for creating menus etc. Now My Problem Goes like This :
I pass a parameter "temp" from file1.asp to file2.asp through link
i.e.
<a href="http://localhost/file2.asp?temp=somevalue>pass param</a>

Now I receive the temp variable in file2.asp as follows :

dim temp
temp=request.querystring("temp")

Now I want to assign the value of "temp" to a variable inside javascript in file2.asp, Iam unable to receive the value bcoz I dont know the javascript equivalent of "request.querystring" ,
please help.

Hi there,

There are basically two ways to do this: from the client with JavaScript, or from the server with ASP code by writing the values to the JavaScript.

Method 1:
You can use document.location.search to retrieve the entire QueryString in JavaScript. This will return the entire QueryString, including the question mark. You'll need to do some string parsing to get at the individual parameters.

Method 2 (much easier):
Use <%= temp %> to write the value of the temp var to a client side JavaScript block, like this:

Code:

<script language="JavaScript" type="text/javascript">
  var jsTemp = '<%=temp%>';
</script>

When the ASP page loads, it will dump the value for temp between the ''s in the JavaScript code block, so you end up with a valid value for your JavaScript variable.

Hope this helps,

Imar

You just need to pass the variable from asp to javascript, something like this in file2.asp:

Code:

<script language="javascript" type="text/javascript">
var yourJavascriptVariable = <%=Request.QueryString("temp")%>;
...
</script>

An alternative is to use the javascript property window.location.search in file2.asp, which will give you the string "temp=something", but it seems easier to me to use the asp method.
