将日期功能合二为一
我正在为基于语音的应用程序的日期提取工作。我想知道如何查看日期，还可以在一个函数中添加用户要求更高日期的标记。现在我正在使用类似的功能，但如果有人可以指导我做一个，那就太好了。我的代码如下，
checkedDateFlag，checkedDate如何在一个中创建此函数，以便我可以获得正确的日期并获得标记（true）
Code
let ent = [{
entity: 'sys-number',
location: [23, 25],
value: '12',
confidence: 1,
metadata: {
numeric_value: 1
}
},
{
entity: 'sys-date',
location: [23, 40],
value: '2017-02-16',
confidence: 1,
metadata: {
calendar_type: 'GREGORIAN',
timezone: 'GMT'
}
},
{
entity: 'sys-number',
location: [36, 40],
value: '2018',
confidence: 1,
metadata: {
numeric_value: 2018
}
},
{
entity: 'sys-date',
location: [49, 52],
value: '2030-12-17',
confidence: 1,
metadata: {
calendar_type: 'GREGORIAN',
timezone: 'GMT'
}
}
];
const dateChecker = (filteredDates, currentDate) => {
// This function checking date higher than todays date and replace higher date with current date.
return filteredDates.map(f => {
let fd = new Date(f);
if(fd > currentDate) {
return currentDate;
} else {
return fd;
}
})
}
const dateCheckerFlag = (filteredDates, currentDate) => {
// This function return true if date is higher and I can check it later and create response saying you have provided higher date than today. I can only issue statement till today and then issue the statement
for (let f of filteredDates) {
let fd = new Date(f);
if(fd > currentDate) {
return true
} else {
return false;
}
}
let filteredDates = ent.filter(f => {
if (f.entity === 'sys-date') {
return f.value
}
}).map(f => f.value);
let checkedDateFlag = helper.dateCheckerFlag(filteredDates, currentDate);
let checkedDate = helper.dateChecker(filteredDates, currentDate);
我建议不要将这两个功能结合起来。虽然他们似乎做同样的事情，但他们有完全不同的输出签名（布尔与数组）。
如果你认为他们有很多重复的代码。也许以下可能是一种方法。我将留下组合和单独的功能。但强烈推荐单独的一个。
