var per = {Period: {"From":["W" + (moment().format('WW')-11)],"To":["W" + moment().format('WW')]}};;

var show = function (studios, platforms, vodest, sdhd, category, genre) {
var output = {
    Studios: studios,
    Platforms: platforms,
    VODEST: vodest,
    SDHD: sdhd,
    Category: category,
    Genre: genre
};

};
$.extend(output, per);
$('.list').html(JSON.stringify(output));

当我运行上述代码时，我得到一个错误ReferenceError:输出未定义是否有一种方法可以将输出变量作为全局变量并在函数外访问它?

var per = {Period: {"From":["W" + (moment().format('WW')-11)],"To":["W" + moment().format('WW')]}};;
var output = {};
var show = function (studios, platforms, vodest, sdhd, category, genre) {
    output['Studios'] = studios,
    output['Platforms']= platforms,
    output['VODEST']= vodest,
    output['SDHD']= sdhd,
    output['Category']= category,
    output['Genre']= genre
};
$.extend(output, per);
$('.list').html(JSON.stringify(output));

试试这个方法:)

var per = {
    Period: {
        "From":["W" + (moment().format('WW')-11)],
        "To": ["W" + moment().format('WW')]
    }
};
function show (studios, platforms, vodest, sdhd, category, genre) {
    return {
    Studios: studios,
    Platforms: platforms,
    VODEST: vodest,
    SDHD: sdhd,
    Category: category,
    Genre: genre
    };
}
var output = show('s', 'p', 'v', 's', 'c', 'g');
output = $.extend(output, per);
$('.list').html(output);
