javascript - Javascript の順次実行

Question

こんにちは、javascript を順次実行できません。イベントはどのように発生しますか。ステートメントが連続して配置されていても、実行はクレイジーです..

6 から 0 までのカウントダウン番号が必要です。その後、Div タグにランダムな文字列を表示します。

 function getRandomArbitrary(min, max) {     //function to pick question randomly based on math calculations
    var temp = Math.floor(Math.random() * (max - min) + min)

  return (temp > max) ? getRandomArbitrary(min,max): temp;
};

function questions(){       //returns the Question pattern

    var htmlQ = new Array("Canon","Mysql","Cisco","FaceBook","Vimeo","Yahoo","Sony","Ebay","Google","HP","Microsoft","Dell","EAGames","Digg","Adobe");

//Sequential execution (i need the count down first then the strings to be displayed in div tag)
$("div").html(counter($("div"), 6)).fadeIn('slow'); $("div").html(questions()).fadeIn('slow');
