Adding Script to ASPX page

Question

Hi I want to add google book preview button to my website. Its code is something like :

<script> GBS_setLanguage('en');</script>            
<script>GBS_insertPreviewButtonPopup('ISBN:0596009208');</script>

Now the problem is I get the ISBN number from the previous page. So I have to include this in C# code on the page. So how this can be done ? I tried doing it but it just does not compile

Used this code to do what I wanted... But it places the script/ google preview button (in my case) to either header or the footer . But no other way to do this.

         HtmlGenericControl script1 = new HtmlGenericControl("script");
        script1.Attributes.Add("type", "text/javascript");
        script1.Attributes.Add("src", "http://books.google.com/books/previewlib.js");
        this.Page.Header.Controls.Add(script1);

        string GoogleScript = "";

        string isbncode = "";
        if (Page.Request.QueryString["isbn"] != null)
            isbncode = Page.Request.QueryString["isbn"];

        GoogleScript = "GBS_setLanguage('en'); GBS_insertPreviewButtonPopup('ISBN:";
        isbncode = isbncode + "');";

        HtmlGenericControl script3 = new HtmlGenericControl("script");
        script3.Attributes.Add("type", "text/javascript");
        script3.InnerHtml = GoogleScript + isbncode ;
        this.Page.Controls.Add(script3);

You should've injected that Javascript using RegisterClientScriptBlock as Sarwar026 suggested - much cleaner (and intended) way of doing such sort of things. — Andrey, Apr 08 '12 at 18:38

You can easily include the ISBN as a querystring parameter in the url and pull it into your javascript code without the need for server side includes. As seen here:

function getQueryString() {
  var result = {}, queryString = location.search.substring(1),
      re = /([^&=]+)=([^&]*)/g, m;

  while (m = re.exec(queryString)) {
    result[decodeURIComponent(m[1])] = decodeURIComponent(m[2]);
  }

  return result;
}

//url: www.yourwebsite.com?isbn=123456789
var _ISBN = getQueryString()["isbn"];
GBS_setLanguage('en');
GBS_insertPreviewButtonPopup(_ISBN);
