根据我提交的网址,有两个匹配项。他们是 'en-gb'和'uk-ireland'
网址:https://www.myabcalphabeta.com/en-gb/destinations/uk-ireland
但是当我返回该函数时,它只返回最后一个,即'uk-ireland'
如何捕捉第一场比赛“en-gb”。我也看到循环工作正常,因为它返回两个值。
$(document).ready(function(){
function getURLLocale() {
var url = $(location).attr("href");
var localeRegex = /^[a-z][a-z]-[a-z][a-z]/g;
var urlBreakdown = url.split("/");
console.log(urlBreakdown);
var lang = "en";
var country = "gb";
for(var i = 0; i < urlBreakdown.length; i++) {
if(urlBreakdown[i].match(localeRegex)) {
lang = urlBreakdown[i].split("-")[0];
country = urlBreakdown[i].split("-")[1];
console.log(lang+ "\n");
};
}
return([lang, country]);
} // End function getURLLocale()
console.log(getURLLocale());
})

我认为你可以这样做:
const url = `https://www.myabcalphabeta.com/en-gb/destinations/uk-ireland`
const getUrlData = url => {
const en = url.match(/\ben-?\w*\b/)
const uk = url.match(/\buk-?\w*\b/)
const result = []
if (en) result.push(en[0])
if (uk) result.push(uk[0])
return result
}
console.log(getUrlData(url))
或者这个
const url = `https://www.myabcalphabeta.com/en-gb/destinations/uk-ireland`
const getUrlData = url => {
const regex = /\b[a-z]{2}-[a-z]*\b/g
const result = []
let temp
while (temp = regex.exec(url)) {
result.push(temp[0])
}
return result
}
console.log(getUrlData(url))
这会选择以2 [a-z]
开头的任何部分,然后必须开始单词 - 以及所有[a-z]
,直到不是单词

使用正则表达式exec
从网址(\w{2}-\w{2,})
获取所有区域设置。
$(document).ready(function () {
function getURLLocale() {
var url = 'https://www.myabcalphabeta.com/en-gb/destinations/uk-ireland';
var m;
var regex = /(\w{2}-\w{2,}(-\w{2})?)/g;
var locales = [];
while (m = regex.exec(url)) {
locales.push(m[0]);
}
return locales;
} // End function getURLLocale()
console.log(getURLLocale());
});
该数组将包含两个语言环境。如果您只想获取第一个而不是getURLLocale()
,请打印getURLLocale()[0]
。
修改强>
我将正则表达式更改为(\w{2}-\w{2,}(-\w{2})?)
,因此您可以匹配this列表中的任何可能的区域设置

你的表情错了:
将正则表达式更改为^[a-z][a-z]-[a-z][a-z]$
$(document).ready(function(){
function getURLLocale() {
var url = "https://www.myabcalphabeta.com/en-gb/destinations/uk-ireland";
var localeRegex = /^[a-z][a-z]-[a-z][a-z]$/g;
var urlBreakdown = url.split("/");
console.log(urlBreakdown);
var lang = "en";
var country = "gb";
for(var i = 0; i < urlBreakdown.length; i++) {
if(urlBreakdown[i].match(localeRegex)) {
lang = urlBreakdown[i].split("-")[0];
country = urlBreakdown[i].split("-")[1];
console.log(lang+ "\n");
};
}
return([lang, country]);
} // End function getURLLocale()
console.log(getURLLocale());
})
