AngularJS相当于jQuery的toggle显示/隐藏一个section

AngularJS equivalent to jQuery toggle show/hide a section

本文关键字：section 一个 隐藏 jQuery 相当于 toggle 显示 AngularJS      更新时间：2023-09-26

首先，是的，我试过谷歌一下，但是仍然很难找到关于AngularJS的信息。

我想执行一个简单的任务，根据在表单中按下的按钮打开部分。我希望只有一个部分在任何时候都是开放的，也许是一个默认的(还没有决定)。如果你点击的按钮将被归类为"btn-primary"，那就太好了。这是html

<form>
    <input type="button" id="show-section1" value="Section 1" />
    <input type="button" id="show-section2" value="Section 2" />
    <input type="button" id="show-section3" value="Section 3" />
</form>
<section id="section1">blah</section>
<section id="section2">blah2</section>
<section id="section3">blah3</section>

在jQuery中，我会这样做(简化的，不是最好的解决方案只是解释):

$('section').hide();
$('#show-section1').click(function() {
    $('section').hide();
    $('#section1').show();
});
etc

我以前这样做过一次，但我不记得是怎么做的，我记得只有很少的几行代码。

如果一次只需要一个，可以使用:http://jsfiddle.net/jHhMv/3/

JS: 

'use strict';
var App=angular.module('myApp',[]);
function Ctrl($scope){
    var section = 1;
    $scope.section = function (id) {
        section = id;   
    };
    $scope.is = function (id) {
        return section == id;
    };
}
HTML: 

<div ng-controller="Ctrl">
<form>
    <input type="button" id="show-section1" value="Section 1" ng-click="section(1)" ng-class="{'btn-primary': is(1)}" />
    <input type="button" id="show-section2" value="Section 2" ng-click="section(2)" ng-class="{'btn-primary': is(2)}" />
    <input type="button" id="show-section3" value="Section 3" ng-click="section(3)" ng-class="{'btn-primary': is(3)}" />
</form>
<section id="section1" ng-show="is(1)">blah</section>
<section id="section2" ng-show="is(2)">blah2</section>
<section id="section3" ng-show="is(3)">blah3</section>
</div>

看看http://jsfiddle.net/mahbub/jHhMv/

<div ng-controller="Ctrl">
<form>
    <input type="button" id="show-section1" value="Section 1" ng-click="section1=!section1" />
    <input type="button" id="show-section2" value="Section 2" ng-click="section2=!section2" />
    <input type="button" id="show-section3" value="Section 3" ng-click="section3=!section3" />
</form>
<section id="section1" ng-show="section1">blah</section>
<section id="section2" ng-show="section2">blah2</section>
<section id="section3" ng-show="section3">blah3</section>
</div>

'use strict';
var App=angular.module('myApp',[]);
function Ctrl($scope){
}

方法很多。其中之一(使用AngularUI):

HTML: 

<div ng-controller="AppController">
    <button ng-click="setActive('section1')" ng-class="{'btn btn-primary': active.section1}">Section 1</button>
    <button ng-click="setActive('section2')" ng-class="{'btn btn-primary': active.section2}">Section 2</button>
    <button ng-click="setActive('section3')" ng-class="{'btn btn-primary': active.section3}">Section 3</button>
    <section id="section1" ui-toggle="active.section1">blah</section>
    <section id="section2" ui-toggle="active.section2">blah2</section>
    <section id="section3" ui-toggle="active.section3">blah3</section>
</div>
CSS: 

.ui-show {
  opacity: 1;
  transition: all 0.5s ease;
}
.ui-hide {
  opacity: 0;
  transition: all 0.5s ease;
}

JS: 

app.controller('AppController',
  function($scope) {
    $scope.active = {section1: true};
    $scope.setActive = function(section){
      $scope.active = {};
      $scope.active[section] = true;
    };
  }
);

恰好
