循环进度条未按期望的百分比停止

Question

我正在为我的项目创建循环进度条。

Desired Progress Circle

我在html css和jquery中完成了以下操作，但问题是我没有得到如何以所需的百分比停止它。它总是完成100％。我想在特定点停止它。

HTML / CSS JS

＆＃13;

＆＃13;

function setProgress(elem, percent) {
    var
      degrees = percent * 3.6,
      transform = /MSIE 9/.test(navigator.userAgent) ? 'msTransform' : 'transform';
    elem.querySelector('.counter').setAttribute('data-percent', Math.round(percent));
    elem.querySelector('.progressEnd').style[transform] = 'rotate(' + degrees + 'deg)';
    elem.querySelector('.progress').style[transform] = 'rotate(' + degrees + 'deg)';
    if (percent >= 50 && !/(^|\s)fiftyPlus(\s|$)/.test(elem.className))
        elem.className += ' fiftyPlus';
}

(function () {
    var
      elem = document.querySelector('.circlePercent'),
      percent = 0;
    (function animate() {
        setProgress(elem, (percent += .25));
        if (percent < 100)
            setTimeout(animate, 15);
    })();
})();

请帮助我。

更新了您的代码，现在我已将变量stopPercent设置为50。因此，加载将在50%处停止。这是你需要的吗？

＆＃13;

＆＃13;

function setProgress(elem, percent) {
    var
      degrees = percent * 3.6,
      transform = /MSIE 9/.test(navigator.userAgent) ? 'msTransform' : 'transform';
    elem.querySelector('.counter').setAttribute('data-percent', Math.round(percent));
    elem.querySelector('.progressEnd').style[transform] = 'rotate(' + degrees + 'deg)';
    elem.querySelector('.progress').style[transform] = 'rotate(' + degrees + 'deg)';
    if (percent >= 50 && !/(^|\s)fiftyPlus(\s|$)/.test(elem.className))
        elem.className += ' fiftyPlus';
}

   (function () {
var elem = document.querySelector('.circlePercent'),percent = 0,stopped = false,stopPercent = 50;
(function animate() {
    setProgress(elem, (percent += .25));
    if (percent < 100 && !stopped)
        setTimeout(animate, 15);
		if(percent == stopPercent){
			stopped = true;
		}
})();
})();
