Continue on the next else if if value is not true

I have written a code that checks some conditions.

But i got stumble on this part. I have used the continue; but it doesn't run and says it has an error.

if (support_Fixednodes !== undefined && support_Fixednodes !== null){

    if ((arrayIndex.length - 1) === arrayIndex.lastIndexOf("FIXED")){

      var supportFBnode_index = checkIfElementExist(dataTwo, "FIXED");

    }else if ((dataTwo.length - 1) !== dataTwo.lastIndexOf("FIXED")){

      continue; <-- This doesn't work.if this part of IF is true i want it to 
                    jump to the next else if

    }


}else if (check_PinnedSupports.BoleanValue === "Existing"){   <----jump here

  var supportFBnode_index = checkIfElementExist(dataTwo, "PINNED");

}
