jQuery实现html可联动的百分比进度条
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。
