javascript - "Update Integer Value"函数不完全准确

Question

我正在使用 JavaScript 函数来跟踪/更新文件夹内的文件数量。大多数时候它相当准确，但误差幅度约为 10%。我认为这与“totalItemCount”变量未正确更新有关。我已经找了好几个小时了，但找不到我可能搞砸的地方。这是一个很长的文件，但实际上您需要查看的只是“totalItemCount”变量

new ApiClient({
    //marketing (69 Files, 40 Folders, 109 total, 204MB): 7f6d706e-6754-e411-b5b8-d4ae5294c399

    {
        var result = JSON.parse(responseText);
        var originalObject = result; //first, top-level object
        var totalItemCount = 0;
        var filesize = 0;

        totalItemCount += parseInt(result.response.totalCount);

        //Check if object has children and add to totalItemCount accordingly FOR EACH object:

        function getItemsRecursively(totalItemCount1, filesize1)
        {
            for(var i = 0; i < parseInt(totalItemCount); i++) //at this point, totalCount == #objects at this lvl
            {
                var currentObject = result.response.items[i];

                {
                    getChildrenItemCount(totalItemCount1, currentObject, filesize1);
                }

            }
        }

        function getChildrenItemCount(totalItemCount2, previousObject, filesize2)
        {
            //totalItemCount2 = totalItemCount;
            var childID = previousObject.id;

                    var currentFolderItemCount = currentObject.totalCount;

我无法对我当前的代表发表评论，因此对 SO 社区作为答案发布感到抱歉。

很高兴看到 totalCount 是如何设置的(其中显示 result.response.totalCount)。

此外，我建议删除所有 console.log。这使得阅读你的代码变得非常困难。

如果一个文件夹包含一个文件夹，那么它是否符合您的文件条件？如果是这样，您的代码中有这样的逻辑吗？

一旦您按照我的建议进行更新，我很乐意再看一眼。

更新:尝试此代码。我无法测试，所以你会让我知道它是如何工作的。

var totalItemCount;
new ApiClient({
apimethod: 'objects/95750c6b-84f5-4587-8b86-b559551f7660/children/view',
method: 'get',
queryparams: {
    maxcount: 8000,
    startindex: 0,
    includefuturepublished: true
},
onSuccess: function (responseText) {

    var result = JSON.parse(responseText);
    totalItemCount = parseInt(result.response.totalCount);

    getItemsRecursively();
}
});

function getItemsRecursively() {

    for(var i = 0; i < parseInt(totalItemCount); i++) {

        var currentObject = result.response.items[i];

        if(currentObject.size != undefined) {
            filesize += currentObject.size;

            if(currentObject.numchildren > 0 && currentObject.numchildren != undefined) {
                getChildrenItemCount(currentObject);
            }

        }
    }
}



function getChildrenItemCount(previousObject) {
    var childID = previousObject.id;
    new ApiClient
    ({
        apimethod: 'objects/' + childID + '/children/view',
        method: 'get',
        queryparams: {
            maxcount: 8000,
            startindex: 0,
            includefuturepublished: true
        },
        onSuccess: function (responseText) 
        {
            var result = JSON.parse(responseText);
            var currentFolderItemCount = result.response.totalCount;

            for(var i = 0; i < parseInt(currentFolderItemCount); i++) 
            {
                var currentObject = result.response.items[i];

                if(currentObject.numchildren > 0 && currentObject.numchildren != undefined)
                {
                    totalItemCount += parseInt(currentObject.numchildren);
                    getChildrenItemCount(currentObject);
                }

            }
        }
    })
}
