angular.js - 关于ng-model和ng-bind的疑问

Question

双向绑定，一般来说是这样

<input ng-model="object.xxx">
<span ng-bind="object.xxx"></span>

也就是说ng-bind是相当于{{object.xxx}}，是用于展示数据的。而ng-model是控制数据的。

但在这里，我从后台获取到设备号后，输出到页面，对input使用的是ng-model，使用ng-bind是没有反应的，为什么？

Answer 1

<input type="text" ng-value="object.xxx" readonly="readonly" />

$('#input1').html('123');    //ng-bind
$('#input1').val('123');    //ng-value

Answer 2

How did you obtain the device number?

If you implement ajax yourself, you need to manually $scope.$apply();
after getting the data If $http is used to obtain data, angular will automatically call $apply().

ng-bind is a one-way binding from $scope -> view
ng-modle is a two-way binding from $scope <-> view
