why cant i send to solr using jquery post/get function?

[Faire Mii]

when i enter http://localhost:8983/solr/select/?q=body:hello in the  
URL field i get all the results.

but when i'm using jquery code:
$.post('http://localhost:8983/solr/select/?q=body:hello, function(data){
        alert(data);
});


OR

$.post('http://localhost:8983/solr/select/?, {q: 'body:hello'},  
function(data){
        alert(data);
});


i get nothing. it doesnt give me anything. it doesnt even give me an  
alert.

i have tried $.get as well without result.

what could the problem be?
