A problem was happened in Ext4 about iframe element. Who can help me?

[nozer]

I want show a page in the Ext.window use iframe.

It's my code:

var window = Ext.create('Ext.window.Window', {
    title: '供求详情', 
    autoScroll: true, 
    layout: 'fit', 
    modal: true, 
    frame: true, 
    frameHeader: true, 
    html: '<iframe src="http://www.jiezanke.com/Supply/SupplyDetail.html"></iframe>' 
}).show();

When I test the window,I can't see the iframe element.This element(iframe) seems to have been filtered out.What do I do? In ext4.My English sucks,everybody sorry.

i would use the items config instead of html and add an iframe with the autoEl:

if you prefer the html, i would inspect the dom with the debugging tools, probably the iframe just needs height and width set to 100%.

Thanks tobiu,

I was change my code:

var window = Ext.create('Ext.window.Window', {
            title: '供求详情',
            autoScroll: true,
            layout: 'fit',
            modal: true,
            items:[{
                xtype: 'component',
                autoEl: {
                    tag: 'iframe',
                    src: 'http://www.jiezanke.com/Supply/SupplyDetail.html'
                }
                        }]
        }).show();
