JSON.stringify转换为变量

Question

I need solution. Look please:

setInterval(function(){
    alert(JSON.stringify(dragposition));
},1000);

It works great. It shows me json code.
But I need put json in variable. Something like this:

var json_text = JSON.stringify(dragposition);
setInterval(function(){
    alert(json_text)
},1000);

But it's not working. (Shows '{{}}' )
dragposition is ui.position from jQuery ui.

Answer 1

what about

var json_text;
setInterval(function() { 
  json_text = JSON.stringify(dragposition); 
  alert(json_text);
}, 1000);

json_text will be accessible out of the setInterval loop
