从最后一个值应用css属性的循环

标签： javascript jquery html loops

我用数据行属性制作了几个div。我想循环每个div并从data-line属性中获取自己的值，并将宽度应用于％，但它只需要最后一个值并将它们全部应用。

你可以在这里查看我的代码。

＆＃13;
＆＃13; 
(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();
})();

您在processBar循环中使用for来更新CSS宽度。由于processBar是所有.process元素的集合，因此当您在其上调用.css时，所有元素都会发生变化。尝试使用.eq(i)仅更改该集合的i-th索引处的元素。

加号我不明白你为什么要使用两个循环。您可以直接在each中应用CSS（您可以使用$(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();
})();

您可以使用非常简单的代码执行此操作。无需编写如此长的功能。

$('.process').each(function(){
    var width = $(this).data('line');
    $(this).css('width',width+'%');
});
