Passing values between different windows

11 New Member

Hello JS newsgroup

The main window of my Website opens a child window as you can see
below:

Expand|Select|Wrap|Line Numbers

 
<script language="JavaScript"> 

    window.name = 'Iamparentwindow' 
 
    function openwindow() 

    { 

        var child2 = window.open("Test.htm","childwin","height=350,width=280"); 

        child2.focus(); 

        child2.document.childform.text1.value = 

            document.parentform.testtext2.value; 

    } 

</script>

I have some questions

1. the 3rd line of function openwindow is generating errors- Could you
please help me fix that ?

2. In the child window, I have used
opener.document.parentform.testtext1.value =
document.childform.text2.value;

which is working fine. But I would like to use the name of opener
window, "Iamparentwindow" instead.
Could you please help me?

Thank you in advance

Heya, Evrim.

Please use CODE tags when posting source code. See the REPLY GUIDELINES on the right side of the page next time you post.

What error are you getting?
You can set up a reference by adding this line:
Expand|Select|Wrap|Line Numbers
1. var lamparentwindow = window.opener;
However, the parent window's variables are not directly available to the child window except via window.opener.

Thank you for the reply. I will try to stick to the guidelines :-)

This is the error I get :
document.childform.text1 is null or not an object.

However, I should mention that not always I get this error. Sometimes when I hit the refresh button several times and I try to open the child window the value is correctly transferred. But for example if I close the child window and try to open it again I get error.

I am using IE 6 and Win XP Professional. My development tool is NetBeans IDE.

Thanks for your help,
Evrim

What does the HTML code for the form "childform" look like?

This is the code of the child window page - As you may see I even removed the line that sets the text1.value in childwindow from the parent window and placed it in the child window page --- but no use - So I returned things the way they were .

[HTML]<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>JSP Page</title>

<script language="JavaScript">

function closewindow()
{

opener.document.parentform.testtext1.value = document.childform.text2.value;

window.focus();
window.close();

}
</script>
</head>

<body>

<h3> Testing with JS pass </h3>

<form method="POST" name="childform">

This is filled from parent <Br>
<input type="text" name="text1" value="" /> <BR>
Filled back to parent <Br>
<input type="text" name="text2" value="" /> <BR>

<input type="button" value="Select" onclick="closewindow()"/>
</form>
</body>
</html>[/HTML]

The reason why you get this error is that the window has not fully loaded, so the child form is not yet accessible. Run the code onload.
