배열로 데이터 전송.

cateArr = document.getElementsByName("cate[]");////받을 배열 객체
 cateHtml = "";

 for(var i=0; i<cateArr.length; i++){
  if(cateArr[i].checked == true){//체크박스일때..
   cateHtml += "&" + encodeURIComponent("cate[]") + "=" + encodeURIComponent(cateArr[i].value); //->cate[]로 ..
  }
 }

 url = "/php/managerPointExe.php";
 params = "mode="+mode+"&id="+id+"&name="+name + cateHtml ;
//배열로 넘길때..cate[]

 sendRequest(url, params, registerRst, 'POST'); //ajax 전송



--------결과----------------------------------
[cate] => Array ( [0] => 0.0001 [1] => 0.0002 )
