I know there are question have been asked around resembling to this one, but still I am not getting proper concept of this. I am currently loading an iframe through javascript in following manner:

jQuery('.out-div-login').html(<iframe id='parent' frameBorder='0' width='320' height='500' src='+_url+'></iframe>);  

Which is working fine. (its cross domain). After loading my application inside given iframe, I want to come back to original state where .out-div-login was loading iframe into parent html.

From outside of iframe I can do this by accessing iframe using its id attribute, but not from the inside. Is there any way I can reload the iframe by giving its src again ? or by above code but from inside the iframe ? Thanks.

Update

I have tried below code without any success as of now:

var ifr = $('iframe[id=parent]');  

from one of js file inside iframe with id parent. when I do console.log(ifr) it gives in firebug something like this Object[] instead of <iframe id=parent>
