<button id="jquery-button">JQuery Button</button>
<div id="jquery-content">I am jquery content</div>
$(function(){
$("#jquery-button").click(function(){
$('#jquery-content').toggle();
})
}) 

--首先要在页面中添加div，然后在js中添加相应的代码
<button id="jquery-button">JQuery Button</button>
<div id="jquery-content">I am jquery content</div>
<div id="jquery-content1">I am jquery content1</div>
$(function(){
$("#jquery-button").click(function(){
$('#jquery-content').toggle();
$('#jquery-content1').toggle();
})
})

<div ng-app="app" ng-controller="AppCtrl as app">
<button ng-click="app.toggle()">Angular Button</button>
<div ng-hide="app.isHidden">Angular content</div>
</div>
var app = angular.module("app",[]);
app.controller("AppCtrl", function(){
var app = this;
app.isHidden = false;
app.toggle = function(){
app.isHidden = !app.isHidden;
}
})

--我们只要在页面中添加一个div,通过ng-hide属性来声明
<div ng-app="app" ng-controller="AppCtrl as app">
<button ng-click="app.toggle()">Angular Button</button>
<div ng-hide="app.isHidden">Angular content</div>
<div ng-hide="app.isHidden">Angular content1</div>
</div>
