鉴于此:
const MATCH_NAME = /\s+([a-z]+)\s+/i;
function parseDates(input) {
const parts = input.split(MATCH_NAME);
const result = {
dates: [],
year: null
};
while (parts.length > 2) {
const [days, month, suffix] = parts.splice(0, 2);
result.dates.push({
month,
days: days.split(/\D+/),
suffix
});
}
result.year = parts[0];
return result;
}
console.log(parseDates('12-5 November 17 May 1954 CE'));
console.log(parseDates('1 January 1976 CE'));
console.log(parseDates('12 22 March 1965'));
year
obj的结尾类似于1976 CE
,而CE
应该位于suffix
。
尝试前往:
Month: November
Days: 12, 5
Month: May
Days: 17
Year: 1954
Suffix: CE
答案 0 :(得分:1)
根据我的理解,你的模式是这样的:
<= 31
,那么它应该被推到天数组。注意:如果我的理解是正确的,那么以下解决方案将对您有所帮助。如果没有,请分享不一致之处。
function parseDates(input) {
var parts = processHTMLString(input).split(/[-–,\/\s]/g);
var result = [];
var numRegex = /\d+/;
var final = parts.reduce(function(temp, c) {
if (numRegex.test(c)) {
let num = parseInt(c);
if (temp.year || (temp.month && num < 31)) {
result.push(temp);
temp = {};
}
temp.days = temp.days || []
if (c.indexOf("-") >= 0) {
temp.days = temp.days.concat(c.split("-"));
} else if (num > 31)
temp.year = c;
else
temp.days.push(c)
} else if (c.length < 3 && temp.year) {
temp.suffix = c
} else {
temp.month = c;
}
return temp;
}, {});
result.push(final);
return result;
}
function processHTMLString(str) {
var div = document.createElement("div");
div.innerHTML = str;
// This will process ` ` and any other such value.
return div.textContent;
}
console.log(parseDates('12-5 November 2007 ce 17 May 1954 Ce'));
console.log(parseDates('1 January 1976 CE'));
console.log(parseDates('12 22 March 1965'));
