Question

我有一个支持两种语言的网站。在Chrome中，切换语言效果很好，但在Firefox中，我点击哪个按钮并不重要，对于“英语”或“德语”语言，它总是为默认设置的德语设置我的语言变量

有人可以帮我解决这个问题吗？

这是我调用getLangCookie函数的示例函数

 <?php
    function convert_number_to_words($number) {

        $hyphen      = '-';
        $conjunction = ' and ';

        $negative    = 'negative ';
        $decimal     = ' point ';
        $dictionary  = array(
            0                   => 'zero',
            1                   => 'one',

我认为你应该把ajax请求放到onload函数上，就像这样。

function getLangCookie(lang) {
    var name = lang + "=";
    var ca = document.cookie.split(';');
    for (var i = 0; i < ca.length; i++) {
        var c = ca[i];
        while (c.charAt(0) == ' ') c = c.substring(1);
        if (c.indexOf(name) == 0) {
            return c.substring(name.length, c.length);
        }
    }
    return "";
}
// by clicking on English button set the cookie value
function onEnglishbtn() {
    setLangCookie("lang", "en", 30);

    document.location.reload();
    var lang = getLangCookie('lang');

    return lang;
}

function setLangCookie(lang, value, exdays) {
    var d = new Date();
    d.setTime(d.getTime() + (exdays * 24 * 60 * 60 * 1000));
    var expires = "expires=" + d.toGMTString();
    document.cookie = lang + "=" + value + "; " + expires;
}
// function onload from index.html setting up the lang by default
window.onload = function () {
    var lang_cookie = getLangCookie('lang');
    console.log('lang_cookie = ', lang_cookie);
    // if cookie doesn't exist
    if (lang_cookie !== null) {
        setLangCookie("lang", "de", 30);
    } // if cookie exists
    else {
        console.log('lang_cookie exists!');
        setLangCookie("lang", lang_cookie, 30);
    }

    $.ajax({
        type: "GET",
        url: '/menu.xml',
        dataType: "xml",
        success: function (xml) {
            $(xml).find('description ' + lang_cookie).each(function () {
                $(this).parent().html($(this).html());
            }
            );
            var menu = [];
            var data = $.xml2json(xml)['#document'];
            that.menu = data.menu;
            console.log('menu = ', that.menu);
        }
    });
}

改变语言在Firefox中不起作用
