问题描述

我搜索了很多东西,却找不到任何东西。我想制作一个带有圆角的进度条。进度条需要具有阴影。到目前为止,我所做的只是在这里:



  $(。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},{时长:3000,缓动: swing,步骤:function(p){bar.css({transform: rotate(  +(45+(p * 1.8))+ deg)}); val.text(p | 0);}});});  

< pre class = snippet-code-css lang-css prettyprint-override> body {background-color:#3F63D3; } .progress-bar {位置:相对;边距:4px;向左飘浮;文本对齐:居中;}。barOverflow {位置:相对;溢出:隐藏;宽度:150像素;高度:70px; margin-bottom:-14px;}。bar {position:absolute;最高:0;左:0;宽度:150像素;高度:150px;边界半径:50%;框大小:border-box;边框:15px纯灰色;边框底部颜色:白色; 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>  



我想使转角并带有阴影。下面给出的图像代表了我真正想要的。阴影不见了,因为我不知道要画画。 :





我尝试了 Progressbar.js ,但是我对SVG知之甚少。任何答案都将不胜感激。

解决方案


@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); }  

 < script src = https:// rawgit .com / kimmobrunfeldt / progressbar.js / 1.0.0 / dist / progressbar.js>< / script>< link href = https://fonts.googleapis.com/css?family=Raleway:400,300,600,800,900 rel = stylesheet type = text / css>< div id = container>< / div>  


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.

解决方案

@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 );
  }

<script src="https://rawgit.com/kimmobrunfeldt/progressbar.js/1.0.0/dist/progressbar.js"></script>
<link href="https://fonts.googleapis.com/css?family=Raleway:400,300,600,800,900" rel="stylesheet" type="text/css">
<div id="container"></div>
