AngularJs directive使用自定义filter

/**

             * @shrink true -- will put wy at the end ,
             *                should use this only when the number is multiple of 100,
             *                or with decimal 2 will lose the money in position 1 and 2
             *                slMoney(11230,true)--> 1<small>.12万元</small> , 30 will lost

// js使用
sl.directive('slPlanCard', ['$sce', '$filter',
function($sce, $filter){
  amountObj.innerHTML = $filter('slMoney')(amount, true, true);
}

 

<!-- html使用 -->
 <p>{{ plan.minInvestAmount | slMoney:true:true }}</p>
