我似乎无法将中心的值(文本)设为100% - 相反,如果值设置为100%
则会显示00%
。
以下是我的内容:Demo / fiddle
$(document).ready(function($) {
function animateElements() {
$('.progressbar').each(function() {
var elementPos = $(this).offset().top;
var topOfWindow = $(window).scrollTop();
var percent = $(this).find('.circle').attr('data-percent');
var percentage = parseInt(percent, 10) / parseInt(100, 10);
var animate = $(this).data('animate');
if (elementPos < topOfWindow + $(window).height() - 30 && !animate) {
$(this).data('animate', true);
$(this).find('.circle').circleProgress({
startAngle: -Math.PI / 2,
value: percentage,
thickness: 14,
fill: {
color: '#1B58B8'
}
}).on('circle-animation-progress', function(event, progress, stepValue) {
$(this).find('div').text(String(stepValue.toFixed(2)).substr(2) + '%');
}).stop();
}
});
}
// Show animated elements
animateElements();
$(window).scroll(animateElements);
});
&#13;
.progressbar {
display: inline-block;
width: 100px;
margin: 25px;
}
.circle {
width: 100%;
margin: 0 auto;
margin-top: 10px;
display: inline-block;
position: relative;
text-align: center;
}
.circle canvas {
vertical-align: middle;
}
.circle div {
position: absolute;
top: 30px;
left: 0;
width: 100%;
text-align: center;
line-height: 40px;
font-size: 20px;
}
.circle strong i {
font-style: normal;
font-size: 0.6em;
font-weight: normal;
}
.circle span {
display: block;
color: #aaa;
margin-top: 12px;
}
&#13;
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>

非常感谢任何帮助。
答案 0 :(得分:1)
你的问题就在这一行:
$(this).find('div').text(String(stepValue.toFixed(2)).substr(2) + '%');
永远不会允许百分比字符串超过2个字符。正确的修复将涉及转换值而不是截断前导值。
一个便宜的解决方案是检查价值是&#34; 00&#34;并将其转换为100,如:
$(this).find('div').text(String(stepValue.toFixed(2)).substr(2) + '%');
if(String(stepValue.toFixed(2)).substr(2) == "00"){
$(this).find('div').text('100%');
}

感谢SteveMitcham的评论,你也可以用以下代码替换:
$(this).find('div').text((stepValue*100).toFixed(0) + "%");
