AngularJS ng-显示具有多个元素的一个条件 [英] AngularJS ng-show one condition with multiple elements

问题描述

我有三个带有showMe"布尔值的 ng-click div.他们的段落有一个 ng-show 来评估showMe".

我的问题是，如何使用一个条件在我单击的 div 上显示段落?换句话说，如果我点击第一个 div，我应该只看到1"，2"和3"段落应该保持隐藏.ng-repeat 不是本练习的选项.

谢谢.

解决方案

你可以这样做:

<div ng-controller="AppCtrl"><div class="box" ng-click="showMe = 1"><p ng-show="showMe ==1">1</p>
<div class="box" ng-click="showMe = 2"><p ng-show="showMe==2">2</p>

<div class="box" ng-click="showMe = 3"><p ng-show="showMe ==3">3</p>

I have three divs with an ng-click with a "showMe" boolean. Their paragraphs have an ng-show that evaulates "showMe".

My question is, how can I use one condition to show the paragraph on the div I click? In other words, if I click the first div, I should only see "1", the "2" and "3" parapgraphs should stay hidden. ng-repeat is not an option for this exercise.

Here's a JSBin:

解决方案

You can do like this :

<div ng-app="app">
<div ng-controller="AppCtrl">
  <div class="box" ng-click="showMe = 1">
    <p ng-show="showMe ==1">1</p>
  </div>
  <div class="box" ng-click="showMe = 2">
    <p ng-show="showMe==2">2</p>
  </div>
  <div class="box" ng-click="showMe = 3">
    <p ng-show="showMe ==3">3</p>
  </div>
</div>
