An example of showing and hiding the menu in the upper right corner of the web page on WeChat public platform-WeChat Development-php.cn

WeChat’s official jsapi provides an interface operation interface, which is used to control the menu in the upper right corner of the WeChat web page. Let’s take a look at the description of the interface operation interface in WeChat’s official documentation.

Hide the menu interface in the upper right corner

wx.hideOptionMenu();

Batch hide function button interface

wx.hideMenuItems({
    menuList: [] // 要隐藏的菜单项，只能隐藏“传播类”和“保护类”按钮，所有menu项见附录3
});

Copy after login

Batch display function button interface

wx.showMenuItems({
    menuList: [] // 要显示的菜单项，所有menu项见附录3
});

Copy after login

Hide all non-basic button interfaces

wx.hideAllNonBaseMenuItem();
// “基本类”按钮详见附录3

Copy after login

Show all function button interface

wx.showAllNonBaseMenuItem();

Copy after login

Implementation code steps

First, jsp interface introduces js library

<script src="http://res.wx.qq.com/open/js/jweixin-1.1.0.js"> </script> 
 <script src="http://libs.baidu.com/jquery/2.0.0/jquery.js"></script>

第四、调用第二步button按钮的功能js代码，在wx.ready中添加

// 8 界面操作接口 开始----------
  // 8.1 隐藏右上角菜单
  document.querySelector(&#39;#hideOptionMenu&#39;).onclick = function () {
    wx.hideOptionMenu();
  };
 
  // 8.2 显示右上角菜单
  document.querySelector(&#39;#showOptionMenu&#39;).onclick = function () {
    wx.showOptionMenu();
  };
 
  // 8.3 批量隐藏菜单项
  document.querySelector(&#39;#hideMenuItems&#39;).onclick = function () {
    wx.hideMenuItems({
      menuList: [
        &#39;menuItem:readMode&#39;, // 阅读模式
        &#39;menuItem:share:timeline&#39;, // 分享到朋友圈
        &#39;menuItem:copyUrl&#39; // 复制链接
      ],
      success: function (res) {
        alert(&#39;已隐藏“阅读模式”，“分享到朋友圈”，“复制链接”等按钮&#39;);
      },
      fail: function (res) {
        alert(JSON.stringify(res));
      }
    });
  };
 
  // 8.4 批量显示菜单项
  document.querySelector(&#39;#showMenuItems&#39;).onclick = function () {
    wx.showMenuItems({
      menuList: [
        &#39;menuItem:readMode&#39;, // 阅读模式
        &#39;menuItem:share:timeline&#39;, // 分享到朋友圈
        &#39;menuItem:copyUrl&#39; // 复制链接
      ],
      success: function (res) {
        alert(&#39;已显示“阅读模式”，“分享到朋友圈”，“复制链接”等按钮&#39;);
      },
      fail: function (res) {
        alert(JSON.stringify(res));
      }
    });
  };
 
  // 8.5 隐藏所有非基本菜单项
  document.querySelector(&#39;#hideAllNonBaseMenuItem&#39;).onclick = function () {
    wx.hideAllNonBaseMenuItem({
      success: function () {
        alert(&#39;已隐藏所有非基本菜单项&#39;);
      }
    });
  };
 
  // 8.6 显示所有被隐藏的非基本菜单项
  document.querySelector(&#39;#showAllNonBaseMenuItem&#39;).onclick = function () {
    wx.showAllNonBaseMenuItem({
      success: function () {
        alert(&#39;已显示所有非基本菜单项&#39;);
      }
    });
  };
 
  // 8.7 关闭当前窗口
  document.querySelector(&#39;#closeWindow&#39;).onclick = function () {
    wx.closeWindow();
  };
 // 8 界面操作接口  结束------------------------------------------

这些js方法注释已经写的很明白，每个方法对应一个button按钮功能

There are four parameters in the above jsp code. These four parameters are the credentials for successfully calling WeChat jsapi, which are appId (required). Fill in, the unique identification of the public account), timestamp (required, the timestamp of generating the signature), nonceStr (required, random string to generate signature), signature (required, signature), for readers who don’t know how to generate these four parameters, please check the menu in the upper left corner of this page, which has a detailed introduction, here No need to elaborate.

Sixth, after the above code is run, the effect is as follows
