apparently know want do, using jquery's ajax methods. there can enable post method.

jquery.ajax({    async:true,    type: "post",    url: ("/yourtarget.php"),      datatype : 'json',      data: {email : 'jeremy'},      success : function(data){          alert("success");      },      error : function(xmlhttprequest, textstatus, errorthrown) {         alert("error");     }  });
