javascript - 循环应用最后一个值的 css 属性

Question

我制作了几个带有数据行属性的div。我想循环每个 div 并从数据行属性中获取自己的值并以 % 的形式应用于宽度，但它只获取最后一个值并将其全部应用。

你可以在这里查看我的代码。

(function processLine() {
		var processBar = $('.process');
		var percent = $('.process-percent .percentage');
		//var id = setInterval(frame, 15);

		function frame() {
			var arrData = [];
			processBar.each(function() {
				var processData = $(this).data('line');
				if (arrData.indexOf(processData) !== processData) {
					arrData.push(processData);
				}
			});


			for (var i = 0; i < arrData.length; i++) {
					processBar.css({
						'width': arrData[i] + '%'
					});
			}

		}

		frame();
})();

.process-bar {
    position: relative;
    max-width: 265px;
    height: 15px;

Answer 1

您正在 for 循环内使用 processBar 来更新 CSS 宽度。由于 processBar 是所有 .process 元素的集合，因此当您对其调用 .css 时，所有元素都会发生更改。尝试使用.eq(i)仅更改该集合的i-th索引处的元素。

加上我不明白你为什么要使用两个循环。您可以直接在 each 内部应用 CSS(您可以在其中使用 $(this) 来定位当前元素:

function frame() {
    processBar.each(function() {
        var processData = $(this).data('line');
        $(this).css({
//        ^^^^ instead of processBar which changes the whole collection
            'width': processData + '%'
        });
    });
}

(function processLine() {
  var processBar = $('.process');
  var percent = $('.process-percent .percentage');

  function frame() {
    processBar.each(function() {
      var processData = $(this).data('line');
      $(this).css({
        'width': processData + '%'
      });
    });
  }

  frame();
})();

.process-bar {
  position: relative;
  max-width: 265px;
  height: 15px;
  background-color: #e4e4e4;
  -webkit-border-radius: 8px;
