    Modifying your original script:

function init()
  if (!checkData()) // checking to see if the data is present
    return false ; // will end only if checkData() is false
  // otherwise, it will continue on with the other stuff...

function checkData()
  if (the data is not there)
    // hey, you have no data!
    return false ;
  return true ;
