前言

　　微信的接口调试工具可以编辑自定义菜单，不过是提交json格式数据创建菜单，非常的不方便还容易出错。网上的工具不好用，所以就自己写了一个。

正文

　　先用bootstrap排个页面框架出来，调用自定义菜单接口需要用到AccessToken,放个输入框输入AccessToken。也不排除想直接输入AppId和AppSecret来获取AccessToken的用户，所以还需要下拉菜单来选择是输入AccessToken还是直接获取AccessToken。为了兼顾微信企业号应用创建菜单还需要AgentId,CorpId,套件永久授权码，SuiteId,SuiteSecret,SuiteTicket,参数的输入框大致就是这些。

　　使用knockout定义好observables监控属性。并绑定到输入框上。

　　　定义菜单展示及菜单编辑模块，排版为微信公众号菜单三个大菜单，每个大菜单下面可以配五个子菜单。大致思路如下，页面排版为六行三列，三个大菜单未配置满时在右侧显示增加菜单按钮，

每个父级菜单的子菜单未配置满时在上方显示增加菜单按钮。未配置满时以空白div占位。

　　定义个函数生成自定义长度数组

　　使用knockout定义好菜单监控属性，格式为

{
 "button": [
  {
   "name": "父级菜单1",
   "sub_button": [
    {
     "type": "view",
     "name": "子菜单1",
     "url": ""
    }
   ]
  },
  {
   "name": "父级菜单1",
   "sub_button": [
    {
     "type": "view",
     "name": "子菜单2",
     "url": ""
    },
    {
     "type": "view",
     "name": "子菜单1",
     "url": ""
    }
   ]
  }
 ]
}

　　定义添加，编辑，删除菜单函数，定义添加编辑菜单时临时监控属性，定义当前编辑菜单索引的监控属性。

　　一个一个编辑菜单还不是很方便，所以还要定义菜单的上下左右的移动，及复制粘贴功能。

function MenuFormValidate() {
   $("#MenuForm").validate({
    rules: {
     name: {
      required: true
     },
     value: {
      required: false
     }
    },
    messages: {
     name: {
      required: "请输入名称"
     },
     value: {
      required: $("#txtMenuButtonValue").attr("placeholder")
     }
    }
   });
  }

     var menus = JSON.stringify(model.Menus());

    },
MenuIndex: ko.observable(), //父级菜单索引

绑定好监控属性，生成菜单排版

最后增加菜单的查询函数及发布函数。因为编辑菜单方便，菜单对象和微信自定义菜单接口所需要的json格式不对应，所以在查询现有菜单和发布菜单时，需要对json数据进行一下格式变化。,

 EditMenus: function (isQuery) {
     if (isQuery == undefined) {
      var menu = {};
      menu.button = new Array();
      model.Menus(menu);
     } else {
      var appId = model.AppId();
      var appSecret = model.AppSecret();
      var accessToken = model.AccessToken();
      var type = model.Type();
      var tokenType = model.TokenType();
      var corpId = model.CorpId();
      var permanentCode = model.PermanentCode();
      var agentId = model.AgentId();
      var suiteId = model.SuiteId();
      var suiteSecret = model.SuiteSecret();
      var suiteTicket = model.SuiteTicket();
      if (type === "1" && tokenType === "2") {
       if (appId == undefined || $.trim(appId).length === 0) {
        alert("请输入AppId");
        return;
       }
       if (appSecret == undefined || $.trim(appSecret).length === 0) {
        alert("请输入AppSecret");
        return;
       }
      } else if (type === "2" && tokenType === "2") {
       if (corpId == undefined || $.trim(corpId).length === 0) {
        alert("请输入CorpId");
        return;
       }
       if (permanentCode == undefined || $.trim(permanentCode).length === 0) {
        alert("请输入永久授权码");
        return;
       }
       if (agentId == undefined || $.trim(agentId).length === 0) {
        alert("请输入AgentId");
        return;
       }
       if (suiteId == undefined || $.trim(suiteId).length === 0) {
        alert("请输入SuiteId");
        return;
       }
       if (suiteSecret == undefined || $.trim(suiteSecret).length === 0) {
        alert("请输入SuiteSecret");
        return;

        return;
       }
