jquery $('head').append and facebook share
i thought this was going to be simple but i don't know why is not working...
When you make facebook share button and you want some special image on the fb share, you put something like this in the <head> of the page:
<link rel="image_src" href="image.jpg" />
Facebook will then grab this image and put it in the post.
but i create this image after the page is loaded. so i wanted to put this piece of code into the after the page is loaded. I tried with this code:
$('head').append('<link rel="image_src" href="image.jpg" />');
but for some reason it doesnt work?
so how do i do that - append this piece of code into page after the page is loaded AND 开发者_开发技巧that facebook share button will grab this image?
thank you, Peter
you can check how facebook reads your site here: URL Linter
i think they only process html without executed javascript
The share-window loads the HTML of the site you want to share after you've clicked the share button. I personally don't think that it is able to execute JavaScript. Even if it could, it would have a different session and post-data. Also it get's cached.
In my experience it's just parsing the HTML without executing JavaScript.
If you use XFBML you could try calling FB.XFBML.parse(); after you appended the image, but I don't think this will work.
Maybe using the Open Graph tags instead could be a solution
