首先,是的,我试过用谷歌搜索,但仍然很难找到有关 AngularJS 的信息。

我想根据表单中按下的按钮执行一个简单的打开部分的任务。我只想随时打开一个部分,也许是一个默认部分(尚未决定)。如果您单击的按钮将被归类为引导程序的“btn-primary”,那也很好。所以这是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,我会做这样的事情(简化而不是解释的最佳解决方案):

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

我以前做过一次,但我不记得是怎么做的,我记得那只是几行代码。

如果你一次只需要一个,你可以使用这个: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;
    };
  }
);

普朗克
