问题:使用组件component时组件无法从外获取到绑定的数据
先贴上官方component的介绍及demo地址:https://docs.angularjs.org/guide/component;
将confirm-dialog.html插入到main.html页面,并将vm.agreemnt传入到confirm.dialog.html中
main.html
在此页面中使用cost-info来传输数据,将main.controller中的vm.agreement传递给cost-info ,on-cancel,on-agree用来绑定事件
<div class="container">
<confirm-dialog cost-info = ‘$ctrl.agreement‘ on-cancel=‘$ctrl.cancleRentalBicycleHandler()‘ on-agree=‘$ctrl.returnBicycleHandler()‘> </confirm-dialog>
</div>
cost-info:用来传输数据,将main.controller中的vm.agreement传递个cost-info
main.controller
vm.agreement = {
‘name‘:‘会捕鼠的鱼‘,
‘age‘:‘18‘
}
function cancleRentalBicycleHandler(){ // do something } function returnBicycleHandler(){ // do something }
confirm-dialog.html
<div class="dialog"> <div class="weui-mask"></div> <div class="weui-dialog"> <div class="weui-dialog__bd">description :{{ $ctrl.costInfo.name }}</div> <div class="weui-dialog__bd">bicycleCode :{{ $ctrl.costInfo.age}}</div> <div class="weui-dialog__ft"> <span ng-click="$ctrl.cancelHandler()" class="weui-dialog__btn weui-dialog__btn_default">再骑一会</span> <span ng-click=" $ctrl.agreeHandler() " class="weui-dialog__btn weui-dialog__btn_primary">确认还车</span> </div> </div> </div>
confirm-dialog.component.js
在confirm-dialog的controller中进行绑定事件的处理
angular.module(‘XXX‘).component(‘confirmDialog‘, { templateUrl: ‘confirm.dialog.html‘, controller: confirmDialogController, bindings:{ costInfo:‘<‘,// ‘<‘数据单项传递,‘=’双向传递 onCancel :‘&‘,// ‘&’绑定事件 onAgree:‘&‘ } }); confirmDialogController.$inject = ‘$log‘]; function confirmDialogController($log) { var vm = this; vm.cancelHandler = cancelHandler; vm.agreeHandler = agreeHandler; function cancelHandler() { vm.onCancel(); } function agreeHandler(){ vm.onAgree(); } }
component可以借鉴directive的使用方法.
使用component在binding中costInfo写法是这样的话,在main.html中应该使用cost-info,
