                }
            ];

我的代码中有一个像这样的对象（在我的 html 页面上生成时间线）。如何动态生成这样的对象？如何动态地将内容分配给这些标签（“marker”、“type”）？

要以 JSON 格式输出任何 PHP 变量，请使用json_encode.

下次，问你的意思，而不是让我们在评论中哄骗你，好吗？;)

JSON 代表 JavaScript 对象表示法。在 JavaScript 中，它用于定义 javascript 对象。从 JSON 构建的 JavaScript 对象基本上是键值对的集合。

由于 JavaScript 是一种基于原型的语言（请参见此处：http ://en.wikipedia.org/wiki/Prototype-based_programming ），您可以“动态生成”这种对象，只需为其分配所需的任何 key:pair 值. 例子 ：

var RandomObject = {} //Create an empty key:pair values object
RandomObject["SomeKey"] = "SomeValue";

这基本上会做同样的事情，就好像你这样做了：

var RandomObject = {"SomeKey":"SomeValue"}

现在，您在这里拥有的是一组键：值对。为了动态地重新创建它，您需要首先创建一个 JavaScript 数组，然后为其分配您的 key:pair 值：

var DynamicDates = new Array();
DynamicDates[0] = {
    "marker": "1991", 
    "type": "youtube-video",
    "title": "Ten" ,
    "youtubeId": "VbhsYC4gKy4" ,
    "content": "With the success of Ten, Pearl Jam became a key member of the Seattle grunge explosion."
};

注意：我选择了第二个条目以使其在示例中更短。
