Question

当我尝试在Angular js中为进度圆提供输入值时，仅显示值（20％）并且不显示加载器颜色。请参阅随附的屏幕截图。

如果直接在HTML中给出输入值（20％），则Angular进度正常。但是当尝试绑定值{{count}}时，它只显示值，但是缺少某些css并且不显示进度颜色。

$ scope.count = 20;

(function($) {
    $.fn.loading = function() {

        var backgroundColor = '#ccc';
        var progressColor = '#1abc9c';
        var percent = 90;
        var duration = 2000;

        var DEFAULTS = {
            backgroundColor : '#ccc',
            progressColor : '#1abc9c',
            percent : 90,
            duration : 2000
        };

        $(this)
                .each(
                        function() {
                            var $target = $(this);

                            var opts = {
                                backgroundColor : $target.data('color') ? $target
                                        .data('color').split(',')[0]
                                        : DEFAULTS.backgroundColor,
                                progressColor : $target.data('color') ? $target
                                        .data('color').split(',')[1]
                                        : DEFAULTS.progressColor,
                                percent : $target.data('percent') ? $target
                                        .data('percent') : DEFAULTS.percent,
                                duration : $target.data('duration') ? $target
                                        .data('duration') : DEFAULTS.duration
                            };
                            // console.log(opts);

                            $target
                                    .append('<div class="background"></div><div class="rotate"></div><div class="left"></div><div class="right"></div><div class=""><span>'
                                            + opts.percent + '%</span></div>');

                            $target.find('.background').css('background-color',
                                    opts.backgroundColor);
                            $target.find('.left').css('background-color',
                                    opts.backgroundColor);
                            $target.find('.rotate').css('background-color',
                                    opts.progressColor);
                            $target.find('.right').css('background-color',
                                    opts.progressColor);

                            var $rotate = $target.find('.rotate');
                            setTimeout(function() {
                                $rotate.css({
                                    'transition' : 'transform ' + opts.duration
                                            + 'ms linear',
                                    'transform' : 'rotate(' + opts.percent
                                            * 3.6 + 'deg)'
                                });
                            }, 1);

                            if (opts.percent > 50) {
                                var animationRight = 'toggle '
                                        + (opts.duration / opts.percent * 50)
                                        + 'ms step-end';
                                var animationLeft = 'toggle '
                                        + (opts.duration / opts.percent * 50)
                                        + 'ms step-start';

我相信更改您的进度条data-percent={{count}}以获得引号可以解决您的问题：

<div class="progress-bar position"  ng-class="rotate"  data-percent="{{count}}" data-duration="1000" data-color="#ccc,#f39c12"></div>

另外我不确定你的逻辑，因为你没有发布任何angularjs代码，删除ng-class="rotate"并只放class="rotate" ng-class将表达所以它会认为旋转是$ scope的一些属性，您需要将其设置为：

$scope.rotate='rotate'

但使用：

class="rotate"

应该可以正常工作。

因为所有这些只是一种解决方法和混乱的方法，我建议检查这个并以AngularJS的方式解决：

Angularjs进度圈不适用于动态输入
