Question

我有一个下面的代码片段，其中一个计数每秒钟增加一秒，这个计数会很好，但是我想增加进度条，以增加进度条中的计数：-

$(document).ready(function(){
	secondsStart();
	function secondsStart(){
		var second = 0
		var secondValue;
		var id = setInterval(frame, 1000);
		function frame() {
		    if (second > 60) {
		    	clearInterval(id);
		    } else {
				$('#seconds').html(second);
				second += 1
				if (second == 60) {
					secondsStart()
				}
		    }
		}
	}
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

		<div class="left-half-clipper">
			<div class="first50-bar"></div>
			<div class="value-bar"></div>
		</div>
	</div>

任何人都可以告诉我如何做到这一点。如何根据进度圈中的计数增加进度栏中的红色进度线。

预先感谢您的帮助。

Answer 1

在查看CSS时，应用类p<number>是设置填充百分比的原因。例如，将p10应用于progress-circle，将其填满10％。

让我们删除p10，以便我们从零开始，并添加一行可以每秒更新该类的行。

$('.progress-circle')
    .removeClass("p" + (second-1)) //Remove class p<n-1>
    .addClass("p" + second);       //Add class p<n>

$(document).ready(function() {
  var $seconds = $('#seconds');
  var $progressCircle = $(".progress-circle");

  secondsStart();

  function secondsStart() {
    var second = 0
    var secondValue;
    var id = setInterval(frame, 1000);
    $progressCircle.removeClass("over50");

    function frame() {
      if (second > 60) {
        clearInterval(id);
      } else {
        $seconds.html(second);
        $progressCircle.removeClass("p" + (second - 1)).addClass("p" + second);
        if (seconds > 50) $progressCircle.addClass("over50");
        second += 1
        if (second == 60) {
          secondsStart()
        }
      }
    }
  }
});

如果您希望将其排除在60之外，而不是100上，那么您只需要做一点数学运算就可以知道当前百分比是什么：

const maxValue = 60;                         //set the total
var pct = parseInt(second * 100/maxValue);   //calculate percentage of total
$('.progress-circle')
    .attr("class", "")                       //clear all classes
    .addClass("progress-circle")             //keep our progress-circle class
    .addClass("p" + pct);                    //add the correct %

$(document).ready(function() {
  var $seconds = $('#seconds');
  var $progressCircle = $(".progress-circle");
  var maxValue = 60;
  
  secondsStart();

  function secondsStart() {
    var second = 0
    var secondValue;
    var id = setInterval(frame, 1000);

    function frame() {
      if (second > maxValue) {
        clearInterval(id);
      } else {
        $seconds.html(second);
        var pct = parseInt(second * 100/maxValue);
        $progressCircle.attr("class", "").addClass("progress-circle").addClass("p" + pct);
        if (pct > 50) $progressCircle.addClass("over50");
        second += 1
        if (second == maxValue) {
          secondsStart()
        }
      }
    }
  }

注释：

您的CSS要求当百分比超过50％时，应应用类over50。我添加了一行，当值超过50时添加此类。此外，由于这些样式具有不同的颜色，因此您会注意到绿色的条形出现在> 50处。如果您不希望这样做，则只需将绿色条更改为与另一条相同的颜色（红色）。
我已将片段中经常更新的两个元素存储为变量。这会将整个脚本限制为两次DOM查找，而不是每秒两次。

如何根据计数增加进度条行？
