title: Window.open and pass parameters by post method
body: <p>With window.open method I open new site with parameters, which I have to pass by post method.I've found solution, but unfortunately it doesn't work. This is my code:  </p>
  
  <pre><code>&lt;script  type="text/javascript"&gt;    
  function openWindowWithPost(url,name,keys,values)
  {
      var newWindow = window.open(url, name);
  
      if (!newWindow) return false;
  
      var html = "";
      html += "&lt;html&gt;&lt;head&gt;&lt;/head&gt;&lt;body&gt;&lt;form id='formid' method='post' action='" + url +"'&gt;";
  
      if (keys &amp;&amp; values &amp;&amp; (keys.length == values.length))
          for (var i=0; i &lt; keys.length; i++)
              html += "&lt;input type='hidden' name='" + keys[i] + "' value='" + values[i] + "'/&gt;";
  
      html += "&lt;/form&gt;&lt;script type='text/javascript'&gt;document.getElementById(\"formid\").submit()&lt;/sc"+"ript&gt;&lt;/body&gt;&lt;/html&gt;";
  
      newWindow.document.write(html);
      return newWindow;
  }
  &lt;/script&gt;  
  </code></pre>
  
  <p>Next, I create arrays:  </p>
  
  <pre><code>&lt;script type="text/javascript"&gt;    
  var values= new Array("value1", "value2", "value3") 
  var keys= new Array("a","b","c") 
  &lt;/script&gt;  
  </code></pre>
  
  <p>And call function by:  </p>
  
  <pre><code>&lt;input id="Button1" type="button" value="Pass values" onclick="openWindowWithPost('test.asp','',keys,values)" /&gt;   
  </code></pre>
  
  <p>But, when I click on this button, the site test.asp is empty (of course I try get pass values - <code>Request.Form("b")</code>).  </p>
  
  <p>How could I solve this problem, why I can't get pass values? </p>
