Accessing iframe from one page to another page of jsp in javascript function

Question

My Form1.jsp has iframe

<iframe id="results" name="results" style="display: none;"  
width="100%" height="240" frameborder="1"></iframe>

I want to access iframe id in javascript function in My form2.jsp

function Hide() {
  if(document.getElementById("results").style.display=="none")  {
    document.getElementById("results").style.display="block";
  }
}

in the place results string I want to access iframe id from Form1.jsp

And what is the result? Any console errors? Where is form2? In the iFrame? Can you post more HTML? Also you call the function hide but it should show. Also you may want to set the style by script so the test works - try `console.log(document.getElementById("results").style.display)` to see it is likely not "none" when you expect it to be - read here: http://stackoverflow.com/questions/4866229/can-you-check-an-objects-css-display-with-javascript — mplungjan, Nov 28 '16 at 07:06

Try this.

redirect from Myform1.jsp to Myform2.jsp using jsp redirect method

public void response.sendRedirect("Myform2.jsp/?formid=id") throws IOException

add it in form1.jsp.

id = your id, you want to send.

In form2.jsp, Read the Url and get the query.

where we need to add public void response.sendRedirect(String location) throws IOException method. Is it in Form1.jsp or Form2.jsp – Manasa J Nov 28 '16 at 08:35
by using above method we are able to access entire jsp page but i want to access only iframeid from one jsp to another jsp page – Manasa J Nov 28 '16 at 10:01
Ok, Then attach the iframe id with your url , then get it back in the second page using ajax. – hari prasad Dec 01 '16 at 11:03
