微信小程序 点击按钮跳转 csdn

要在微信小程序中实现点击按钮跳转到 CSDN 网站，需要先使用小程序内置的按钮组件，并在其属性中设置跳转链接。具体操作如下：

1. 在小程序页面的 wxml 文件中添加按钮组件，例如：

<button bindtap="redirectToCsdn">进入CSDN</button>

2. 在小程序页面的 js 文件中定义 redirectToCsdn 函数，例如：

redirectToCsdn: function () {
wx.navigateTo({
url: 'https://www.csdn.net'
})
}

3. 在 redirectToCsdn 函数中使用微信小程序的内置函数 navigateTo，设置跳转链接为 CSDN 网站。注意，由于 CSDN 网站使用了 HTTPS 协议，需要在小程序 app.json 文件中配置允许跳转到 HTTPS 网站，例如：

"networkTimeout": {
"request": 10000,
"connectSocket": 10000,
"uploadFile": 10000,
"downloadFile": 10000
},

}]
},
"sitemapLocation": "sitemap.json",

4. 最后，在微信开发者工具中编译并调试上述代码，在微信小程序运行时点击“进入CSDN”按钮即可跳转到 CSDN 网站。
