我正在编写一些指令测试,但由于这个问题基本上是通过jquery插件创建的,因此我遇到了一些问题。
这是指令代码:
var setColor;
setColor = function(value) {
var el, temperatureValue;
el = $('.rs-range-color');
temperatureValue = parseInt(value);
el.attr('class', '');
return el.addClass('rs-path rs-transition rs-range-color animate-color-change temp-' + temperatureValue);
};
$.fn.roundSlider.prototype.defaults.create = function() {
var endLabel, numberTag1, numberTag2, o, startLabel;
o = this.options;
startLabel = this._valueToAngle(o.min);
numberTag1 = this._addSeperator(startLabel, 'rs-tooltip-text custom-label num1 ');
numberTag1.children().html(o.min).rsRotate(-startLabel);
endLabel = this._valueToAngle(o.max);
numberTag2 = this._addSeperator(endLabel, 'rs-tooltip-text custom-label num2 ');
numberTag2.children().html(o.max).rsRotate(-endLabel);
return setColor(o.value);
};
angular.module('Picker', []).directive('TemperaturePicker', function() {
return {
restrict: 'E',
templateUrl: './directives/Picker/temperaturePicker.tpl.html',
replace: true,
link: function(scope, element, attrs) {
element.roundSlider({
min: attrs.min,
max: attrs.max,
radius: attrs.size,
sliderType: 'min-range',
startAngle: 315,
circleShape: 'pie',
width: 20,
value: attrs.value,
step: 0.5,
editableTooltip: true,
tooltipFormat: function(attrs) {
return attrs.value.toFixed(1) + ' °C';
}
});
return element.on('change drag', function(e) {
if (e.value !== void 0) {
return scope.$apply(function() {
return setColor(e.value);
});
}
});
}
};
});
这是我写的测试(如果失败,因为它说element.roundSlider不是函数):
describe('Directive: temperaturePicker', function() {
var $compile, $rootScope;
$rootScope = void 0;
$compile = void 0;
beforeEach(module('hgApp'));
beforeEach(inject(function(_$rootScope_, _$compile_) {
$compile = _$compile_;
return $rootScope = _$rootScope_;
}));
return it('Should check that the directive is created', function() {
var el;
el = $compile("<temperature-picker></temperature-picker>")($rootScope);
$rootScope.$digest();
return expect(el).toBeDefined();
});
});
它在$rootScope.$digest()
后立即失败。
当测试运行时,肯定会调用Roundslider插件,正如您可以在karma调试控制台中看到的那样:

任何类型的帮助都将非常感激。感谢

我相信您想使用jQuery从DOM中选择element
,因此您的链接功能将如下所示:
link: function(scope, element, attrs) {
$(element).roundSlider({ .......
