Question

我正在尝试简单地替换字符串。

function LanguageSwitch (lang) {
    var pathname = window.location.pathname;

    if (lang == "da") {
        pathname = pathname.replace(array("/de/", "/en/"), "/da/");
    }
    if (lang == "en") {
        pathname = pathname.replace(array("/da/", "/de/"), "/en/");
    }
    if (lang == "de") {
        pathname = pathname.replace(array("/da/", "/en/"), "/de/");
    }

    window.location.replace(pathname);
}

这确实有效：

function LanguageSwitch (lang) {
    var pathname = window.location.pathname;

    if (lang == "da") {
        pathname = pathname.replace("/en/", "/da/");
    }
    if (lang == "en") {
        pathname = pathname.replace("/da/", "/en/");
    }

    window.location.replace(pathname);
}

但是添加了第三种语言选择器 - 不是那么多; - ）

任何想法。

编辑：这不是尝试用[a，b，c]替换[x，y，z]，而是用“a”替换[x，y，z]

Answer 1

尝试

function LanguageSwitch (lang) {
    var pathname = window.location.pathname;

    if (lang == "da") {
        pathname = pathname.replace(/\/en\/|\/de\//, "/da/");
    }
    if (lang == "en") {
        pathname = pathname.replace(/\/da\/|\/de\//, "/en/");
    }
if (lang == "de") {
        pathname = pathname.replace(/\/da\/|\/en\//, "/de/");
    }

    window.location.replace(pathname);
}

Answer 2

var pathname = 'www.here-is-lang-da.com';
$('h1').text(pathname);
pathname = pathname.replace(/da|de/g, 'en');
$('h2').text(pathname);
