 var checkVal = null;
 for(i = 0; i < rdsObj.length; i++){
  if(rdsObj[i].checked){checkVal = rdsObj[i].value;}

 return checkVal;
}

function getVals(){
 var res = getCheckBoxRes('rds');
 if(res.length < 1){
  mui.toast('请选择');
  return;
 }
 mui.toast(res);
}
function getCheckBoxRes(className){
 var rdsObj = document.getElementsByClassName(className);
 var checkVal = new Array();
 var k  = 0;
 for(i = 0; i < rdsObj.length; i++){
  if(rdsObj[i].checked){
   checkVal[k] = rdsObj[i].value;
