尝试

structure(list(type = c("human", "human", "human", "mouse", "mouse"
), status = c("living", "living", "dead", "living", "dead"), 
    count = c(36, 57, 43, 4, 8)), row.names = c(NA, -5L), class = c("tbl_df", 
"tbl", "data.frame"))

  var tawktouser = $("#tawktouser").val().split('\n');
  alert(tawktouser[0])
