Why Only returns the last line of the file

[shanelau]

My file‘name is "city.txt",

·58453 beijing 58665 shanghai 58559 china 58652 mmm·

just return the last line "58652 mmm". Tell me why! My code is ·lineReader.open('./city.txt', function(reader) { if (reader.hasNextLine()) { reader.nextLine(function(line) { console.log(line); var result = line.split(" "); //console.log(result[0]+"\t"+result[1]); }); } });·
