post请求返回ok但没有数据和函数不起作用

Ok, I've been putting together a website for the las couple of weeks.

I got everything working before moving on to next phase. Made a lot of changes but none to the functions that I'm talking about.

basically I have a code:

var grabbedItems = [];

function grab(){
$.post(questions.php, {"grab":"grab"}, function(data){
    grabbedItems = data;
    console.log(grabbeditems);
}, "json");
}

The function gets called on page load. The problem is that network tab says 200 ok for questions.php, but console.log() doesn't even log anything. I can't think what i've done wrong. i haven't even changed the page that the function is on. What could be the problem, apache says no errors network says 200 ok. But functions are not working. I don't think there is anything wrong with my JQuery file, that returns 200 ok aswell.

Any help would be appreciated.

The problem was with the data in one of the mysql fields. I used a £ sign. for some reason the JSOn didn't like it. Maybe I should look into the coding of the database entries.
