javascript - 关于计数的 Stop If 和 Else 语句

Question

我想创建显示加载的页面，然后随时间显示随机数，但问题是当加载切换到随机数时，该随机数再次更改为加载(循环)。

这是我的代码:

<div class="spinner" id="box1">
  <div class="double-bounce1"></div>
  <div class="double-bounce2"></div>
</div>
<div class="suhu" style="display:none" id="box2">
 <span style="color: #E74C3C; font-size: 30px; text-align: center;">
    Suhu Anda : </span><span id="decimalgenerate" style="font-size: 30px;"></span><span style="font-size: 30px;">&#8451;<br/></span><span style="color: #E74C3C;"></span>
</div>

这是 JS 代码:

setInterval(function thing() {

      var b1 = document.getElementById('box1');
      var b2 = document.getElementById('box2');

      if(b1['style'].display == 'none')break; {
        b1['style'].display = 'block';
        b2['style'].display = 'none';

      } else {
        b1['style'].display = 'none';
        b2['style'].display = 'block';

      }


    }, 7000);

Answer 1

对于停止间隔，请使用clearInterval

var myTime = setInterval(function thing() {

      var b1 = document.getElementById('box1');
      var b2 = document.getElementById('box2');

      if(b1['style'].display == 'none')break; {
        b1['style'].display = 'block';
        b2['style'].display = 'none';

      } else {
        b1['style'].display = 'none';
        b2['style'].display = 'block';
      }
    }, 7000);

以及您想要的地方

clearInterval(myTime)

示例:

var myTime = setInterval(function thing() {

      var b1 = document.getElementById('box1');
      var b2 = document.getElementById('box2');

      if(b1['style'].display == 'none') {
        b1['style'].display = 'block';
        b2['style'].display = 'none';
        clearInterval(myTime);
      } else {
        b1['style'].display = 'none';
        b2['style'].display = 'block';
      }
    }, 7000);
