在通过Fancybox弹出窗口打开的iFrame中调用javascript函数

Question

I'm trying to call a javascript function in a page opened in an iFrame using jQuery Fancybox.

            $(".testbox").fancybox({
                maxWidth    : 800,
                maxHeight   : 600,
                fitToView   : false,
                autoSize    : false,
                closeClick  : false,
                openEffect  : 'none',
                closeEffect : 'none',
                afterShow: function() {
                        //var frameID = $('#fancybox-frame')
                        //frameID.getParam("test");                         
                    }
            }); 

        $(".testbox").each(function() {
                var element = this;
                $(this).fancybox({
                    'titleFormat'   : function() {
                        var astring = '<span>' + element.id + '</span>';
                        alert(astring);
                    }
                });
            });

HTML:

    <a class="testbox fancybox.iframe" href="include/testFrame.html">Iframe</a>

The function in the testFrame.html I'm trying to call:

        function getParam(param) {              
            alert(param);               
        }

Normally I'd do this when calling functions in iFrame without using a Fancybox popup:

        document.getElementById('myFrame').contentWindow.getParam();

but I don't know how to get the ID of the whole iFrame when using Fancybox. Any help is appreciated!

Edit: I also tried this code which also didn't work, I get the error in IE: Object doesn't support this property or method. I've made sure the page I'm loading has the function

    var $f = $("#fancybox-frame");
    var fd = $f[0].document || $f[0].contentWindow.document; 
    fd.getparam("test");  

Answer 1

You should use:

var $f = $("#fancybox-frame");
$f[0].contentWindow.getParam("test");

Reasons:

• The method is globally declared, not as a method of the document object.
• JavaScript is case-sensitive; getParam is distinct from getparam .
