Question

I am trying render iframe inside a container, but iframe is not getting stretched to full screen.

var htmlInputs = '<input type="hidden" name="amount" value="100.00">' +
            '<input type="hidden" name="currency" value="AUD">';
       {
html: '<iframe scrolling="yes" name="iframe" src="" style="overflow:visible; display:block; position:relative; width=100%; height=100%;"  id="iframe"></iframe>' +
                '<form style="float:right;display:none;" method="post" target="ifrmae" id="ingenicoForm" name=iframeaction="https://*********">' +
                htmlInputs +
                '</form>' ,
            xtype: 'container',
            listeners: {
                afterrender: function() {
                    var form = Ext.getElementById('iframe');
                    form.submit();
                }
     
}
