javascript と skydrive API を使用して Web サイトをプログラミングしています。

これは私のコードです:

var clientId = '00000000400FFB5A';
var redirectUri = "http://milmantasimmigration.com/skydrive/test/test.html";

WL.init({
    client_id: clientId,
    redirect_uri: redirectUri
});

WL.Event.subscribe("auth.login", onLogin);
WL.Event.subscribe("auth.sessionChange", onSessionChange);

var session;
var companyFolders;
var reportFolders;
var reports;

session = WL.getSession();
if (session) {
    log("You are already signed in!");
    getCompanyFolders();
} else {
    WL.login({
        scope: "wl.signin"
    });
}

function onLogin() {
    var session = WL.getSession();
    if (session) {
        log("You are signed in!");
    }
}

function onLogout() {
    WL.logout();
    log("You are logged out!");
}

function onSessionChange() {
    var session = WL.getSession();
    if (session) {
        log("Your session has changed.");
    }
}

function getCompanyFolders() {
    var getCompanyFoldersDeferred = $.Deferred();

    WL.api({
        path: "/me/skydrive/shared",
        method: "GET"
    }).then(

    function(response) {
        companyFolders = [];
        reportFolders = [];
        reports = [];
        for (var i = 0; i < response.data.length; i++) {
            if (response.data[i].type == "folder") {
                companyFolders.push(response.data[i]);
                getReportFolders(response.data[i].id + "/files/", companyFolders.length - 1);
            }
        }
        $.when.apply($, companyFolders).done(function() {
            getCompanyFoldersDeferred.resolve();
        });
    }, function(response) {
        log("Cannot get files and folders: " + JSON.stringify(response.error).replace(/,/g, ",\n"));
    });

    return getCompanyFoldersDeferred.promise();
}

function getReportFolders(path, index1) {
    var getReportFoldersDeferred = $.Deferred();
    //var index2 = 0;

    WL.api({
        path: path,
        method: "GET"
    }).then(

    function(response) {
        reportFolders[index1] = [];

        reports[index1] = [];
        for (var i = 0; i < response.data.length; i++) {
            if (response.data[i].type == "folder") {
                reportFolders[index1].push(response.data[i]);
                //index2++;
                getReports(response.data[i].id + "/files/", index1, reportFolders[index1].length - 1);
            }
        }
        $.when.apply($, reportFolders).done(function() {
            getReportFoldersDeferred.resolve();
        });
    }, function(response) {
        log("Cannot get files and folders: " + JSON.stringify(response.error).replace(/,/g, ",\n"));
    });
    return getReportFoldersDeferred.promise();
}

function getReports(path, index1, index2) {
    var getReportsDeferred = $.Deferred();
    //var index3 = 0;

    WL.api({
        path: path,
        method: "GET"
    }).then(

    function(response) {
        reports[index1][index2] = [];

        for (var i = 0; i < response.data.length; i++) {
            if (response.data[i].type == "file") {
                reports[index1][index2].push(response.data[i]);
                //index3++;
            }
        }
        $.when.apply($, reports).done(function() {
            getReportsDeferred.resolve();
        });
    }, function(response) {
        log("Cannot get files and folders: " + JSON.stringify(response.error).replace(/,/g, ",\n"));
    });
    return getReportsDeferred.promise();
}

getCompanyFolders().done(function() {
    showReportsHTML();
});

function showReportsHTML() {
    for (var i = 0; i < companyFolders.length; i++) {
        for (var j = 0; j < reportFolders[i].length; j++) {
            for (var k = 0; k < reports[i][j].length; k++) {
                alert(reports[i][j][k].name);
            }
        }
    }
}

function log(x) {
    alert(x);
}

この2行

getCompanyFolders();
showReportsHTML();

getCompanyFolders() 関数がジョブを終了した後、関数を次々と実行する必要があります。ただし、getCompanyFolders() がレポートの 3D 配列を埋める前に、showReportsHTML() が実行されます。

getCompanyFolders() が完全に完了した後に showReportsHTML() 関数を起動する方法は?

getCompanyFolders非同期関数を呼び出しているためです。この関数の終了後に何かを実行したい場合は、コールバック関数を提供する必要があります。

function getCompanyFolders(callback) {
    companyFolders = [];

    WL.api({
        path: "/me/skydrive/shared",
        method: "GET"
    }).then(

    function(response) {
        reportFolders = [];
        reports = [];
        for (var i = 0; i < response.data.length; i++) {
            if (response.data[i].type == "folder") {
                companyFolders[companyFolders.length] = response.data[i];
                getReportFolders(response.data[i].id + "/files/", companyFolders.length - 1);
            }
        }
        callback();
    }, function(response) {
        log("Cannot get files and folders: " + JSON.stringify(response.error).replace(/,/g, ",\n"));
        callback();
    });
}

これで、呼び出して引数としてgetCompanyFolders渡すことができます。showReportsHTML

getCompanyFolders(showReportsHTML);
