使用Facebook javascript SDK时出错

Question

Hi for some reason when I invoke GET methodes from a simplemodal dialog they fail with the following error:

Uncaught TypeError: Cannot call method 'toLowerCase' of undefined

the error occurs at line 10 in the facebooks all.js. The same methode succeed when called not from the modal dialog. Also any post method succeed from the modal dialog as well.

The method is a trivial one:

FB.api(postId,'GET', function(response) {
 alert('hello');
} 

Answer 1

I had the same problem with a delete call like this:

FB.api( id, 'delete', function(response) {
    console.log(response);
});

It turns out the problem was that the id was an integer and not a string. I got the id from the URL with PHP and cast it to an int and then output it as javascript using json_encode, so I just had to cast it back to a string to solve the problem. One way to do this with javascript is like this:

var int = 10;
console.log( '' + int );
