@jaromanda用于学习SVG的建议。
是的，从边界半径很难实现。所以我调查了SVG，发现它非常方便。这是我的代码段：
// progressbar.js@1.0.0版本已使用//文件：http://progressbarjs.readthedocs.org/en/1.0.0/var bar = new ProgressBar.SemiCircle（container，{strokeWidth：10，color：'red'，TrailColor：'#eee'， TrailWidth：10，缓动：'easeInOut'，持续时间：1400，svgStyle：null，文本：{value：''，alignToBottom：false}，//为所有动画调用设置默认的step函数step：（state，bar）=> ; {bar.path.setAttribute（'stroke'，state.color）; var value = Math.round（bar.value（）* 100）; if（value === 0）{bar.setText（''）; } else {bar.setText（value +％）;} bar.text.style.color = state.color;}}）; bar.text.style.fontFamily =' Raleway，Helvetica，sans-serif'; bar.text.style.fontSize ='2rem'; bar.animate（0.45）; //从0.0到1.0的数字
#container {width： 200px;高度：100像素；} svg {高度：120像素；宽度：200像素；填充：无；中风：红色；笔划宽度：10；笔画线帽：圆形； -webkit-filter：drop-shadow（-3px -2px 5px gray）;过滤器：drop-shadow（-3px -2px 5px gray）; }

I searched a lot and finding nothing on it. I want to make a progress bar with round corners.progress bar need to have shadow. All I did as of now is here :
$(".progress-bar").each(function(){
var bar = $(this).find(".bar");
var val = $(this).find("span");
var per = parseInt( val.text(), 10);
$({p:0}).animate({p:per}, {
duration: 3000,
easing: "swing",
step: function(p) {
bar.css({
transform: "rotate("+ (45+(p*1.8)) +"deg)"
});
val.text(p|0);
}
});
});
body{
background-color:#3F63D3;
}
.progress-bar{
position: relative;
margin: 4px;
float:left;
text-align: center;
}
.barOverflow{
position: relative;
overflow: hidden;
width: 150px; height: 70px;
margin-bottom: -14px;
}
.bar{
position: absolute;
top: 0; left: 0;
width: 150px; height: 150px;
border-radius: 50%;
box-sizing: border-box;
border: 15px solid gray;
border-bottom-color: white;
border-right-color: white;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="progress-bar">
<div class="barOverflow">
<div class="bar"></div>
</div>
<span>100</span>%
</div>
I want to make corners round and having shadow. below given image represent what actually i want. Shadow is missing because i don't know to draw. :
I have tried Progressbar.js also, but I don't have much knowledge about SVG. Any answer would be appreciated.
@jaromanda for suggestion of learning SVG.
Yes is looks very hard to achieve from border-radius. So i looked into SVG and find it pretty handy. Here is my snippet:
// progressbar.js@1.0.0 version is used
// Docs: http://progressbarjs.readthedocs.org/en/1.0.0/
var bar = new ProgressBar.SemiCircle(container, {
strokeWidth: 10,
color: 'red',
trailColor: '#eee',
trailWidth: 10,
easing: 'easeInOut',
duration: 1400,
svgStyle: null,
text: {
value: '',
alignToBottom: false
},
// Set default step function for all animate calls
step: (state, bar) => {
bar.path.setAttribute('stroke', state.color);
var value = Math.round(bar.value() * 100);
if (value === 0) {
bar.setText('');
} else {
bar.setText(value+"%");
}
bar.text.style.color = state.color;
}
});
bar.text.style.fontFamily = '"Raleway", Helvetica, sans-serif';
bar.text.style.fontSize = '2rem';
bar.animate(0.45); // Number from 0.0 to 1.0
#container {
width: 200px;
height: 100px;
}
svg {
height: 120px;
width: 200px;
fill: none;
stroke: red;
stroke-width: 10;
stroke-linecap: round;
-webkit-filter: drop-shadow( -3px -2px 5px gray );
filter: drop-shadow( -3px -2px 5px gray );
}
