javascript新手想要压缩一些代码

Question

我对PHP有一些乐趣，然后我意识到我真的需要使用JavaScript。所以我做了一些研究，找到了我需要的东西 - 它可以正常工作。

但是有一点问题就是这段代码看起来很糟糕......我对JavaScript的所有了解都是alert("something");的作用类似于echo或print。但语法类似于PHP，所以我稍后可以对你的提示进行一些研究。此外，我不需要任何关于以下代码的安全提示，我已经处理好了。

代码：

    <script type="text/javascript">
function getCook(cookiename) 
  {
  var cookiestring=RegExp(""+cookiename+"[^;]+").exec(document.cookie);
  return unescape(!!cookiestring ? cookiestring.toString().replace(/^[^=]+./,"") : "");
  }

function UpdateBet()
{
var cookieValue = getCook('bet');
document.getElementById("bet0").href="?bet=0&amount=" + cookieValue;
document.getElementById("bet1").href="?bet=1&amount=" + cookieValue;
document.getElementById("bet2").href="?bet=2&amount=" + cookieValue;
document.getElementById("bet3").href="?bet=3&amount=" + cookieValue;

根据评论的建议，使用for循环，您可以尝试类似：

示例： 的

<script type="text/javascript">
//get your cookie, you know what to do
var cookieValue = 'test';

function UpdateBets(){
    var bets = document.getElementsByClassName("bet");
    for (i in bets){
        bets[i].href += cookieValue;
    }
}
</script>

<a href="?bet=0&amount=" class="bet">Bet A</a>
<a href="?bet=1&amount=" class="bet">Bet B</a>
<a href="?bet=2&amount=" class="bet">Bet C</a>
<a href="?bet=3&amount=" class="bet">Bet D</a>
...
...

<script>UpdateBets();</script>
