最近需要一个HTML可以联动的百分比进度条，网上找了一下没有，自己手动实现了一个。

需要解决的问题，AB两个进度条需要按照百分比A+B=100%，A进度条可以拖动，B进度条联动，并且有进度颜色的变化。实现功能如下：

HTML代码：

<div class="percentage-container" >
  <div class="a-percentage" data-x='30'>
   <div class="a-percentage-bar"></div>
  </div>
 <div class="b-percentage" data-x='70'>
   <div class="b-percentage-bar"></div>
  </div>
</div>

CSS代码：

.percentage-container {
 margin: 20px auto;
 width: 600px;
 text-align: center;
}
 
.percentage-container .a-percentage {
 margin: 0;
 width: 400px;
 cursor:pointer;
}
 
.a-percentage {
 float:left;
 padding: 2px;
 background: rgba(0, 0, 0, 0.25);
 border-radius: 6px;
 -webkit-box-shadow: inset 0 1px 2px rgba(0, 0, 0, 0.25), 0 1px rgba(255, 255, 255, 0.08);
 box-shadow: inset 0 1px 2px rgba(0, 0, 0, 0.25), 0 1px rgba(255, 255, 255, 0.08);
}
 
.a-percentage-bar {
 position: relative;
 height: 16px;
 border-radius: 4px;
 -webkit-transition: 0.2s linear;
 -moz-transition: 0.2s linear;
 -o-transition: 0.2s linear;
 transition: 0.2s linear;
 -webkit-transition-property: width, background-color;
 -moz-transition-property: width, background-color;
 -o-transition-property: width, background-color;
 transition-property: width, background-color;
 -webkit-box-shadow: 0 0 1px 1px rgba(0, 0, 0, 0.25), inset 0 1px rgba(255, 255, 255, 0.1);
 box-shadow: 0 0 1px 1px rgba(0, 0, 0, 0.25), inset 0 1px rgba(255, 255, 255, 0.1);
 background: url("img/stripes.png") 0 0 repeat;
 background-color: #FF5400;
}
 
.percentage-container .b-percentage {
 margin: 0;
 width: 400px;
 cursor:pointer;
}
 
.b-percentage {
 float:left;
 padding: 2px;
 background: rgba(0, 0, 0, 0.25);
 border-radius: 6px;
 -webkit-box-shadow: inset 0 1px 2px rgba(0, 0, 0, 0.25), 0 1px rgba(255, 255, 255, 0.08);
 box-shadow: inset 0 1px 2px rgba(0, 0, 0, 0.25), 0 1px rgba(255, 255, 255, 0.08);
}
 
.b-percentage-bar {
 position: relative;
 height: 16px;
 border-radius: 4px;
 -webkit-transition: 0.2s linear;
 -moz-transition: 0.2s linear;
 -o-transition: 0.2s linear;
 transition: 0.2s linear;
 -webkit-transition-property: width, background-color;
 -moz-transition-property: width, background-color;
 -o-transition-property: width, background-color;
 transition-property: width, background-color;
 -webkit-box-shadow: 0 0 1px 1px rgba(0, 0, 0, 0.25), inset 0 1px rgba(255, 255, 255, 0.1);
 box-shadow: 0 0 1px 1px rgba(0, 0, 0, 0.25), inset 0 1px rgba(255, 255, 255, 0.1);
 background: url("img/stripes.png") 0 0 repeat;
 background-color: #FF5400;
}

JS代码：

$(document).ready(function (){
 var w = $('.a-percentage').width();
 var pos_x = $('.a-percentage').offset().left;
 var inti_x = $('.a-percentage').attr('data-x')*4;
 setProgressAndColor(inti_x, w);
 
 $('.a-percentage').click(function(e) { 
 var x = e.originalEvent.x || e.originalEvent.layerX || 0; 
 x = x - pos_x;
 if(x > 0 && x < w){
  setProgressAndColor(x, w);
 }
 });
});

function setProgressAndColor(p, width){
 $('.a-percentage-bar').width(p)
 $('.a-percentage-bar').css('background-color',calcColor(p));
 var per = Math.floor(p/4);
 $('.a-percentage-bar').attr('data-x',per);
 
 $('.b-percentage-bar').width(width-p)
 $('.b-percentage-bar').css('background-color',calcColor(width-p));
 per = 100-per;
 $('.b-percentage-bar').attr('data-x', per);
}

function calcColor(x){
 var R = 255
 var G = 15;
 var tmp = Math.floor(G+x);//取整保证RGB值的准确
 if(tmp <= 255){
 return 'rgb(255,'+tmp+',15)'
 } else {
 R = (R-(tmp-255));
 return 'rgb('+R+',255,15)'
 }
}

用了简单JQuery做支撑，需要引入JQuery看效果。
