我正在尝试在其绑定的ng-model范围变量更改时更新Ion.RangeSlider的值.使用Ion.RangeSlider时模型会更新,反之则不然.当模型值发生变化时,具有相同ng模型的其他输入会更新,因此这必须是一些特殊情况.
编辑:喔!这是一个片段@lin :)也是jsfiddle.
var app = angular.module('ngModelIonRangeSliderDemo',[]); app.controller('MainCtrl',function ($scope,$rootScope,$timeout) { $scope.someNumber = 10; }).directive('ionRangeSlider',function ionRangeSlider() { return { restrict: 'A',scope: { rangeOptions: '=',model: '=ngModel' },link: function (scope,elem,attrs) { scope.$watch('model',function () { elem.ionRangeSlider(scope.rangeOptions); }); } } });

我已经在十多个有点相关的堆栈溢出帖子中尝试了各种建议(这就是我如何设置当前范围.在ngModel上的$watch方案),但没有一个有效.我的控制台中没有任何错误.怎么了?另外,为什么在我的指令中没有提及模型的情况下它是否有效?如果我在这篇文章中没有提到任何重要内容,请告诉我.
只需在你的指令中使用slider.update()就可以了:
