Answer 1

首先，将[0]

• e = user.entry.content。$ t [0];

然后将其转换为html元素；

• g = $（e）[0]; //索引0是div，如果您要查找特定元素，则可以将其替换

最后，您可以将其用作jQuery对象并提取数据值：

• h = $（g）.data（'作者'）

• i = $（g）.data（'cat'）

• j = $（g）.data（'url'）

干杯!

Answer 2

e.data是undefined 。

您正在将e设置为user.entry.content.$t[0]

这意味着e是$t的第一个字符，它看起来"\

长字符串，开头为： "\
