Question

我有一些问题。首先，我用html / jquery做了一个简单的项目。我有简单的注册表和用户列表。

在人们签署我的网站后，我想要编辑用户的名称，用户名等，只保留编辑部分。对不起我没用的英语。但是当你看到代码我相信你会理解。

这是代码。 codepen

var userList = [];

var config = {
    date: {
        day: "2-digit",
        year: "numeric",
        month: "long",
        hour: "numeric",
        minute: "2-digit"
    }
}

var generateGUID = () => {
    var s4 = () => {
        return Math.floor((1 + Math.random()) * 0x10000)
            .toString(16)
            .substring(1);
    }
    return s4() + s4() + '-' + s4() + '-' + s4() + '-' + s4() + '-' + s4() + s4() + s4();

var generateRow = user => `<tr data-info='${JSON.stringify(user)}' >

Answer 1

您可以为每个用户分配一个唯一的ID并将该id与userList数组中的用户数据一起存储，因此当单击编辑按钮时，您可以从userList数组中找到使用该ID的特定用户并更新详细信息。
