javascript - 用纯 Javascript 从 Url 生成 Treeview

Question

我以如下数组的形式获取文件的 URL



我想实现这样的目标

var mainObj = [
{
    name: "Home",
    files: ["excel doc 1.xlsx", "excel doc 2.xlsx"],
    folders: [{
        name: "Procedure",
        files: ["excel doc 2.xlsx"],
        folders: []
    }],
},
{
    name: "BusinessUnits",
    files: [],
    folders:[
        {
            name:"Administration",
            files:[],
            folders:[{
                name: "AlKhorDocument",
                files: [],
                folders:[
                    {
                        name: "Album1",
                        files: [],
                        folders:[......]
                    }
                ]
            }]
        }
    ]
}

]

......
如果你能帮忙，请告诉我。

顺便说一句，我想在下面实现



如果你能提出更好的建议，那么它会帮助我..

通过只有字符串的路径部分，您可以通过减少文件夹结构并将最终文件添加到文件夹结构来减少数组。

var data = ['Home/excel doc 1.xlsx', 'Home/excel doc 2.xlsx', 'Home/Procedure/excel doc', 'Home/Procedure/2.xlsx', 'BusinessUnits/Administration/AlKhorDocument/Album1/text.txt'],
    result = data.reduce((r, p) => {
        var path = p.split('/'),
            file = path.pop(),
            final = path.reduce((o, name) => {
                var temp = (o.folders = o.folders || []).find(q => q.name === name);
                if (!temp) o.folders.push(temp = { name });
                return temp;
            }, r);

        (final.files = final.files || []).push(file);
        return r;
    }, {});

console.log(result);

.as-console-wrapper { max-height: 100% !important; top: 0; }
