如何将“ v”符号更改为“ +”（未折叠时）或“-”（折叠时）。在这里一切正常。我只是想将插入符号更改为+或-
下面是我的代码。我用过boostrap，angular和html
角度控制器
myApp.controller('myController', myController);
myController.$inject = ['$scope'];
function myController($scope, $http) {
// Controller business operation
}
角度指令
(function () {
'use strict';
angular.module('myApp')
.directive('myDirective', function () {
return {
restrict: 'E', //E = element, A = attribute, C = class, M = comment
scope: true,
templateUrl: 'Views/Directives/Ecommerce/template.html',
controller: myController,
controllerAs: 'vm'
}
});
})();
Angular Directive HTML代码
