This is similar to my last question but the problem is different. I use a separate javascript file for all of my javascript functions. That file is called by my main window, and is also called in a separate instance by my child windows. My code works with every browser except IE 9 and 10. I have not tested earlier versions of IE.

IE says the offending line is window.opener.savetoparent($targetval); My previous code was opener.savetoparent($targetval); and before that I simply made the changes to the parent from the child directly. I have also gone into IE and enabled protected mode as suggested in another article with no change in behavior. Savetoparent() is available to both the child and the parent so I must call it with opener for it to run in the parent.

The error I am getting is : Unable to get property 'savetoparent' of undefined or null reference. Here is the code:

function saveandclose($wintype, $propid) {



switch($wintype) {

    case 'ccdetail':

        var $targetval = $('#cc-total').val();

        var $fieldname = 'closingcoststotal';

        break;

}



window.opener.savetoparent($targetval);

closewindow();

}

The safe to parent function is:

function savetoparent($targetval) {

    $('#' + $parentloc).val($targetval);

    var $name = $('#' + $parentloc).attr(name);

    var $rawtargetval = jsstrtonum($targetval);

    processrvsave($propertyid, $name, $rawtargetval);   

    calcrvtotals();

}

Any light you can shed on this would be greatly appreciated.

window is launched like this

if(window.showModalDialog) { 

  window.showModalDialog($childname + '.php?ploc=' + $parentloc + '&propid=' + $propid, '', 'dialogWidth: ' + $winwidth + 'px; dialogHeight: ' + $winheight + 'px;') 

} 

else { 

  window.open($childname + '.php?ploc=' + $parentloc + '&propid=' + $propid, '', 'width=' + $winwidth + ', height=' + $winheight + ', modal=yes'); 

}
