问题描述
使用 ng-repeat 时，编辑内容的最佳方式是什么?
在我的理想情况下，添加的生日是一个超链接，当点击它时会显示一个编辑表单 - 与当前添加表单相同，带有更新按钮.

<ul ng-repeat="bday in bdays">
{{bday.name}} |{{bday.date}}</li><form ng-show="visible" ng-submit="newBirthday()"><标签>名称:</label><input type="text" ng-model="bdayname" placeholder="Name" ng-required/><label>日期:</label><input type="date" ng-model="bdaydate" placeholder="Date" ng-required/><br/><button class="btn" type="submit">保存</button></表单> <div id="push"></div>
<div id="页脚"><div class="容器"><a class="btn" ng-click="visible = true"><i class="icon-plus"></i>添加</a>
App.js:
var app = angular.module('birthdayToDo', []);app.controller('main', function($scope){//开始时不可见，但当点击按钮时，它将显示为真$scope.visible = false;//创建一个数组来保存生日列表$scope.bdays = [];//创建函数将数据推入bdays"数组$scope.newBirthday = function(){$scope.bdays.push({name:$scope.bdayname, date:$scope.bdaydate});$scope.bdayname = '';$scope.bdaydate = '';};});
解决方案
你应该把表单放在每个节点里面，并使用 ng-show 和 ng-hide 来启用和禁用编辑，分别.像这样:
<span ng-hide="editing" ng-click="editing = true">{{bday.name}} |{{bday.date}}</span><form ng-show="editing" ng-submit="editing = false"><标签>名称:</label><input type="text" ng-model="bday.name" placeholder="Name" ng-required/><label>日期:</label><input type="date" ng-model="bday.date" placeholder="Date" ng-required/><br/><button class="btn" type="submit">保存</button></表单>
这里的关键点是:
- 我已将控件
ng-model 更改为本地范围 - 在
form中添加了ng-show，这样我们就可以在编辑时显示它 - 添加了带有
ng-hide 的 span 以在编辑时隐藏内容 - 添加了一个
ng-click，它可以在任何其他元素中，将 editing 切换为 true - 更改了
ng-submit 以将 editing 切换为 false
这是您的更新后的Plunker.
When using ng-repeat what is the best way to be able to edit content?
In my ideal situation the added birthday would be a hyperlink, when this is tapped it will show an edit form - just the same as the current add form with an update button.

var app = angular.module('birthdayToDo', []);
app.controller('main', function($scope){
// Start as not visible but when button is tapped it will show as true
$scope.visible = false;
// Create the array to hold the list of Birthdays
$scope.bdays = [];
// Create the function to push the data into the "bdays" array
$scope.newBirthday = function(){
$scope.bdays.push({name:$scope.bdayname, date:$scope.bdaydate});
$scope.bdayname = '';
$scope.bdaydate = '';
};
});
解决方案
You should put the form inside each node and use ng-show and ng-hide to enable and disable editing, respectively. Something like this:
<li>
<span ng-hide="editing" ng-click="editing = true">{{bday.name}} | {{bday.date}}</span>
<form ng-show="editing" ng-submit="editing = false">
<label>Name:</label>
<input type="text" ng-model="bday.name" placeholder="Name" ng-required/>
<label>Date:</label>
<input type="date" ng-model="bday.date" placeholder="Date" ng-required/>
<br/>
<button class="btn" type="submit">Save</button>
</form>
</li>
The key points here are:
- I've changed controls
ng-model to the local scope
- Added
ng-show to form so we can show it while editing
- Added a
span with a ng-hide to hide the content while editing
- Added a
ng-click, that could be in any other element, that toggles editing to true
- Changed
ng-submit to toggle editing to false
Here is your updated Plunker.
