本文实例为大家分享了微信小程序实现日历签到的具体代码，供大家参考，具体内容如下
wxml:
{{year}}年{{month}}月 {{item}} {{item.dateNum}} 立即签到 立即签到 本月累计签到 X 次未签到 X 次

由于没有设计图，先把功能完善了。可能代码冗杂了，要是有大家有更便捷的写法，欢迎踊跃交流。
好多人需要fun.js的文件，这个文件跟签到的功能并没有关系，还是贴出来，方便大家交流。
//fun.js
const toast = str => {
return new Promise((resolve, reject) => {
wx.showToast({
title: str,
icon: "none",
duration: 2000,
success: () => {
setTimeout(() => {
resolve()
}, 2000)
}
})
})
}
const successToast = str => {
return new Promise((resolve, reject) => {
wx.showToast({
title: str,
icon: "success",
duration: 2000,
success: () => {
setTimeout(() => {
resolve()
}, 2000)
}
})
})
};
const showloading = () => {
return new Promise((resolve, reject) => {
wx.showLoading({
title: "加载中",
success: () => {
resolve()
}
})
})
};
const hideloading = () => {
return new Promise((resolve, reject) => {
wx.hideLoading({

})
};
const tijiaoloading = () => {

})
};
export default {
