I have tried to use the following code to passing value back from the child window back to the parent window

      <tr>
        <th class="clLabel">Unit</th>
        <td>
          <asp:TextBox ID="sUnit" runat="server" MaxLength="12" Width="3em" /> 
        </td>
      </tr>


<script type="text/javascript">

    $("#test").click(function () {
        var parent = $(parent.document.body);
        $(parent).find('input#sUnit').val("test");
        window.close();
    });

</script>

But some how error message always display when it's come to this code of line

NOTE: parent page and the child page is holding in the difference host (will this cause the problem?)

Does anyone know what is it going on? A开发者_如何学运维nd how can I solve it?

Guess this will work.

<script>
$(function (){
     $("#test").click(function () {
        var parent = window.opener.document;
        $(parent).find('input#sUnit').val("test");
        window.close();
    });
})
</script>
<a href="#" id="test">test</a>

UPDATE

the opender Script

<input type="button" onclick="window.open('search.php', '_blank', 'height=200, width=300');" value="launch!" />
<input id="sUnit" value="" type="text"/>
