我的脚本不能在跨度之间循环

Question

当页面被刷新时，它应该循环遍历所有跨度。它似乎只在前两个0和1之间循环

Javascript客户端脚本

  <script>
      var rand1 = Math.round(Math.random());
      $(".sp-" + rand1).removeClass("hidden");
  </script>
  </clientscript>

跨度如下所示

<span class="sp-0 hidden">{CLIENTFIRST} {CLIENTLAST} {CLIENTPARTY}, {CAND4FIRST} {CAND4LAST} {CAND4PARTY}, {CAND1FIRST} {CAND1LAST} {CAND1PARTY}, {CAND2FIRST} {CAND2LAST} {CAND2PARTY}, {CAND3FIRST} {CAND3LAST} {CAND3PARTY}, or {CAND5FIRST} {CAND5LAST} {CAND5PARTY}</span>
<span class="sp-1 hidden"> {CAND3FIRST} {CAND3LAST} {CAND3PARTY}, {CAND1FIRST} {CAND1LAST} {CAND1PARTY}, {CAND2FIRST} {CAND2LAST} {CAND2PARTY}, {CLIENTFIRST} {CLIENTLAST} {CLIENTPARTY}, {CAND5FIRST} {CAND5LAST} {CAND5PARTY}, or {CAND4FIRST} {CAND4LAST} {CAND4PARTY}</span>
<span class="sp-2 hidden">{CAND2FIRST} {CAND2LAST} {CAND2PARTY},  {CAND3FIRST} {CAND3LAST} {CAND3PARTY}, {CAND4FIRST} {CAND4LAST} {CAND4PARTY}, {CAND5FIRST} {CAND5LAST} {CAND5PARTY}, {CLIENTFIRST} {CLIENTLAST} {CLIENTPARTY}, or {CAND1FIRST} {CAND1LAST} {CAND1PARTY}</span>
<span class="sp-3 hidden">{CAND1FIRST} {CAND1LAST} {CAND1PARTY}, {CAND3FIRST} {CAND3LAST} {CAND3PARTY}, {CAND5FIRST} {CAND5LAST} {CAND5PARTY}, {CAND2FIRST} {CAND2LAST} {CAND2PARTY}, {CAND4FIRST} {CAND4LAST} {CAND4PARTY}, or {CLIENTFIRST} {CLIENTLAST} {CLIENTPARTY}</span>
<span class="sp-4 hidden">{CAND4FIRST} {CAND4LAST} {CAND4PARTY}, {CAND5FIRST} {CAND5LAST} {CAND5PARTY}, {CAND1FIRST} {CAND1LAST} {CAND1PARTY}, {CLIENTFIRST} {CLIENTLAST} {CLIENTPARTY}, {CAND3FIRST} {CAND3LAST} {CAND3PARTY}, or {CAND2FIRST} {CAND2LAST} {CAND2PARTY}</span>
<span class="sp-5 hidden">{CAND5FIRST} {CAND5LAST} {CAND5PARTY}, {CLIENTFIRST} {CLIENTLAST} {CLIENTPARTY}, {CAND4FIRST} {CAND4LAST} {CAND4PARTY}, {CAND1FIRST} {CAND1LAST} {CAND1PARTY}, {CAND3FIRST} {CAND3LAST} {CAND3PARTY}, or {CAND2FIRST} {CAND2LAST} {CAND2PARTY}</span>```

Answer 1

Math.random返回从0到(但不包括) 1的值。如果您想获得从0到5的随机值，您必须这样做

Math.round(Math.random()*5)
