Question

我想在其所说的区域中添加个性化消息：＆＃34;特定消息，＆＃34;取决于进度的百分比。

实施例： - 高达15％，显示消息：＆＃34;开始下载..＆＃34; - 最多30％，显示消息：＆＃34;检查新更新...＆＃34;

      progressLabel = $( ".progress-label" );

    progressbar.progressbar({
      value: false,
      change: function() {
      progressLabel.text( progressbar.progressbar( "value" ) + "%" );
    },
    complete: function() {
      progressLabel.text( "Complete!" );
    }
  });

    function progress() {
      var val = progressbar.progressbar( "value" ) || 0;

      progressbar.progressbar( "value", val + 2 );

      if ( val < 99 ) {
        setTimeout( progress, 800 );
      }
    }

    setTimeout( progress, 2000 );
  });
  </script>

<body>

<div id="progressbar"><div class="progress-label">Loading...</div></div>
<span>Specific Message</span>

我希望你能理解我，谢谢

为什么不是一个简单的＆＃39; if＆＃39;声明。给你的跨度一个id =＆＃39; msg＆＃39;并使用此进度功能：

function progress() {
      var val = progressbar.progressbar( "value" ) || 0;

  progressbar.progressbar( "value", val + 2 );

      if(val > 15){
          document.getElementById('msg').innerHTML = 'Checking for new updates';
      }
      if(val > 30){
          document.getElementById('msg').innerHTML = 'Some other msg';
      }
      if(val > 50){
          document.getElementById('msg').innerHTML = 'As many as you like';
      }
      if ( val < 99 ) {
        setTimeout( progress, 800 );
      }
    }

进度条与消息html / javascript
