需要简单的angularjs编程帮助
[英]Need help with simple angularjs programming
问题描述
I am trying to do simple programming in angularjs. 
我正在尝试在angularjs中进行简单的编程。 I have created two buttons. 我创建了两个按钮。 The first button has text "clickHere", and the second has no text. 第一个按钮带有文本“ clickHere”，第二个按钮没有文本。 My task is when I click the button that has text, it will automatically get empty and the second button will have the same text. 我的任务是，当我单击包含文本的按钮时，它将自动为空，而第二个按钮将具有相同的文本。 (and vice versa). （反之亦然）。
var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
$scope.name = 'Superhero';
$scope.name1 = '';
var val = 'Hello';
$scope.click0 = function() {
//alert("hello!");
$scope.name = $scope.name1;
$scope.name1="";
//return val;
};
$scope.click1 = function() {
//alert("hello!");
$scope.name1 = $scope.name;
$scope.name="";
// return val;
};
}
<body ng-app="myApp">
<div ng-controller="MyCtrl">
<button ng-click="click0()" >{{name}}</button>
<button ng-click="click1()" >{{name1}}</button>
</div>
</body>
Here is my code in jsfiddle. 这是我在jsfiddle中的代码。 http://jsfiddle.net/simpleorchid/a65zV/ http://jsfiddle.net/simpleorchid/a65zV/

I think your issue was you were overwriting your stored value. 我认为您的问题是您正在覆盖储值。 I added a $scope variable called word , and now it works: 我添加了一个名为word的$scope变量，现在它可以工作：
var myApp = angular.module('myApp',[]);
function MyCtrl($scope) {
$scope.word = 'Superhero';
$scope.name = $scope.word;
$scope.name1 = '';
$scope.click0 = function() {
$scope.name1 = $scope.word;
$scope.name="";
};
$scope.click1 = function() {
$scope.name = $scope.word;
$scope.name1="";
};
}
