Question

即使kmz文件结束，

Google地球插件时间滑块仍会继续运行。时间似乎永远不会手动停止。请参阅该页面 http://www.sodanjaljet.fi/kuhmo/

其他一些页面的代码代码基本相同，但不会保持运行，它会在kmz文件完成时结束，请参阅页面 http://www.sodanjaljet.fi/uncategorized/viipurinlahti-helmi-maaliskuussa-1940/

下面的问题代码

  {
     google.earth.createInstance('map3d', initCB, failureCB);
  }

  function initCB(instance) 
  {
     var defaultRate = 1; // 1 second in the plugin for each real second.
     var speedyRate = 60*60*24*4; // 1 day for each real second.        
     ge = instance;
     ge.getWindow().setVisibility(true);        
     addSampleButton('Alkuun', camera);
     ge.getNavigationControl().setVisibility(ge.VISIBILITY_SHOW);
     var href = 'http://www.sodanjaljet.fi/wp-content/uploads/kmz/Kuhmo2.kmz';

  function failureCB(errorCode) 
  {

  function camera() 
  {

    lookAt.setLatitude(63.95335);

  function setRate(rate)

    var time = ge.getTime().getTimePrimitive();
    ge.getTime().setRate(eval(0));

  function addSampleButton(caption, clickHandler)

    var btn = document.createElement('input');
    btn.type = 'button';
    btn.value = caption;

  function start()

    timeSpan.getEnd().set('1940-01-03');
    groundOverlay.setTimePrimitive(timeSpan)
    ge.getFeatures().appendChild(groundOverlay);
    ge.getTime().setTimePrimitive(timeSpan);
  }

  google.setOnLoadCallback(init);

  </script>

代码工作正常，有播放，停止和“返回开始”按钮，它们工作。然而，不停止的时间是一个非常烦人的问题。任何想法如何让它停止？
