javascript - reload facebook share dialog while opening it

Question

i know, it is a bit weird question, but I really want to reload facebook share dialog twice after it opens. the reason is that the page to share is new and thats why share dialog doesnot show the og image. only when I reopen the share dialog twice or thrice, then og image shows up.

I need that it shows up in the first share dialog.

I tried:

function shareFB(url) {
 var newwindow = window.open('https://www.facebook.com/sharer/sharer.php?u=' + encodeURIComponent(url),
              'facebook-share-dialog',
                'width=572,height=567');
 newwindow.location.reload(true);
 newwindow.location.reload(true);
}

but it does not have any effect...

any ideas?

Answer 1

ok the solution was just simply to define:

<meta property="og:image:width" content="1200"/>
<meta property="og:image:height" content="630"/>

and it loads image on the first load
