Question

我创建了一个图表，其中条形图值通过HTML添加并根据需要在JS中进行修改。 JS输出的值来自第一个栏，但它没有从其他栏中获取值。

有谁知道如何使该功能输出每个条形的值？

＆＃13;

$('.vertical .progress-fill span').each(function(){
  var to = $(".vertical .progress-fill span.to").html();
  var from = $(".vertical .progress-fill span.from").html();
  
  var percentFrom = from + "%";
  
  var pBottom = 0 + ( from.slice(0, from.length - 1) );
  var pTop = 100 - (to) + "%" ;
  
  var bottom = (pBottom) + "%";
  var top = (to - from) + "%";
  
  $(this).parent().css({
    'height' : top,
    'top' : pTop,
    'bottom' : percentFrom,
  });
});


/*$('.vertical .progress-fill span').each(function(){
  var percent = $(this).html();
  var pTop = 100 - ( percent.slice(0, percent.length - 1) ) + "%";
  $(this).parent().css({
    'height' : percent,
    'top' : pTop

你可以在这里看到代码

Answer 1

那里有几个错误

您没有to和from每个progress-fill。

像

  var to = $(this).find(".to").html();
  var from = $(this).find(".from").html();

将选择器$('.vertical .progress-fill span')更改为$('.vertical .progress-fill')

像

$('.vertical .progress-fill').each(function(){

Answer 2

你正在循环错误的元素。

循环.progress-fill

$('.vertical .progress-fill').each(function(){
  var to = $(this).find(".to").html();
  var from = $(this).find(".from").html();

  var percentFrom = from + "%";

  var pBottom = 0 + ( from.slice(0, from.length - 1) );
  var pTop = 100 - (to) + "%" ;

  var bottom = (pBottom) + "%";
  var top = (to - from) + "%";

  $(this).parent().css({
    'height' : top,
    'top' : pTop,
    'bottom' : percentFrom,
  });
});

Answer 3

问题是你正在遍历所有跨度：

<span class="to">90</span>
<span class="from">20</span>
<span class="to">75</span>
<span class="from">10</span>
<span class="to">60</span>
<span class="from">10</span>
<span class="to">100</span>
<span class="to">50</span>
<span class="from">40</span>
<span class="from">0</span>
<span class="to">70</span>
<span class="from">30</span>

您必须迭代.progress-fill：

$('.vertical .progress-fill').each(function(){
  var $this = $(this);
  var to = $this.find("span.to").html();
  var from = $this.find("span.from").html();

  var percentFrom = from + "%";

  var pBottom = 0 + ( from.slice(0, from.length - 1) );
  var pTop = 100 - (to) + "%" ;

  var bottom = (pBottom) + "%";
  var top = (to - from) + "%";

  $(this).parent().css({
    'height' : top,
    'top' : pTop,
    'bottom' : percentFrom,
  });
});

$('.vertical .progress-fill').each(function(){
  var $this = $(this);
  var to = $this.find("span.to").html();
  var from = $this.find("span.from").html();
 
  var percentFrom = from + "%";
  
  var pBottom = 0 + ( from.slice(0, from.length - 1) );
  var pTop = 100 - (to) + "%" ;
  
  var bottom = (pBottom) + "%";
  var top = (to - from) + "%";
  
  $(this).parent().css({
    'height' : top,
    'top' : pTop,
    'bottom' : percentFrom,
  });
});
