title: conditionally call JavaScript function
body: <p>I have a "Pay" button where we are starting to accept credit card. I need to call a Javascript function from the server side click event. I tried with Response.Write as below but that does not trigger my function that is defined in the separate .js file. What else can I do?</p>
  
  <pre><code>        protected void btmMakePayment_Click(object sender, EventArgs e)
          {            
              if (user selected credit card)
              {
                  Response.Write("&lt;script language='javascript' type='text/javascript'&gt;OpenPayPalDialog();&lt;/script&gt;");
              }
              else
              {
                  continue with the current server side logic
              }
         }
  </code></pre>
  
  <p>Thank You in advance.</p>
