我正在学习angularjs和bootstrap。很简单，但我不知道我在做什么错。关键是要用按钮重新加载页面，但是我无法进入必须重新加载页面的函数。
myApp.component('refreshComponent', {
template:"<button class='btn btn-lg btn-info' ng-click='refresh()' >Refresh </button>",
controller: function RefreshController($scope, $element, $attrs) {
var vm = this;
vm.refresh = function(){
console.log("How to get here?")
location.reload();
}
}
});

顺便说一句，其他组件正在工作var myApp = angular.module('myApp', []);myApp在date.component.js中初始化]
请确保已将controllerAs: 'vm',添加到组件，并将ng-click='refresh()添加到ng-click='vm.refresh()
所以您的组件应该看起来像：
myApp.component('refreshComponent', {
template:"<button class='btn btn-lg btn-info' ng-click='vm.refresh()' >Refresh </button>",
controllerAs: 'vm',
controller: function RefreshController($scope, $element, $attrs) {
var vm = this;
vm.refresh = function(){
console.log("How to get here?")
location.reload();
}
}
});
Tip 1：
如果使用vm，则根本不需要$scope。 A.e。：
function RefreshController($element, $attrs)
提示2：
如果要混淆代码，值得使用$inject以避免意外的行为：
myApp.component('refreshComponent', {
template:"<button class='btn btn-lg btn-info' ng-click='vm.refresh()' >Refresh </button>",
controllerAs: 'vm',
controller: RefreshController
});
function RefreshController($element, $attrs) {
var vm = this;
vm.refresh = function(){
console.log("How to get here?")
location.reload();
}
}
RefreshController.$inject = ['$element', '$attrs'];
