此输入值应为"Paris"，但不会显示.我的代码有什么问题?
This input value should be "Paris" but it does not display. What is wrong with my code?
(function(angular, undefined) {
var mon_app = angular.module('mon_app', []);
angular.module('mon_app').controller('monctrl', function($scope) {})
}(window.angular));<!DOCTYPE html>
<html class="app" ng-app="mon_app">
<head lang="fr" class="app">
</head>

This input value is "Paris"
<input name="lieu" ng-model="lieu" type="text" value="Paris" />
</div>

您不能混合使用常规HTML(输入的 value 属性)和角度驱动的 ng-model .输入将始终显示 ng-model 中的值，此处为 lieu ，因此应使用Paris值对 $ scope.lieu 进行初始化.
You cannot mix regular HTML (the value attribute of your input) and the angular-driven ng-model. The input will always display the value of what's in ng-model, here lieu, hence you should iniialize $scope.lieu with the Paris value.
(function(angular, undefined) {
var mon_app = angular.module('mon_app', []);
angular.module('mon_app').controller('monctrl', function($scope) {
$scope.lieu = "Paname";
})
}(window.angular));<!DOCTYPE html>
<html class="app" ng-app="mon_app">
<head lang="fr" class="app">
</head>
<body>
<div ng-controller="monctrl">
This input value is "{{lieu}}"
<input name="lieu" ng-model="lieu" type="text"/>
</div>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/angularjs/1.3.10/angular.js"></script>
