这篇文章给大家分享的是有关如何使用asp.net mvc,boostrap及knockout.js开发微信自定义菜单编辑工具的内容。小编觉得挺实用的，因此分享给大家做个参考，一起跟随小编过来看看吧。
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
}
},

required: "请输入名称"
},
value: {
required: $("#txtMenuButtonValue").attr("placeholder")
}
}
});
}

isEditMenu: ko.observable(false), //是否是编辑菜单
BottonIndex: ko.observable(-1), //编辑菜单的父级菜单索引
SubBottonIndex: ko.observable(-1), //编辑菜单的子菜单索引

</div>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。,
