I have the following text that is inside of a long string called content.
我有一个名为content的长字符串内的以下文本。
data-seq="0123abcd"
Previously I was using the following to match characters but I am not sure if the correct way to do this and it does not work for number of characters that are not eight.
以前我使用以下内容来匹配字符，但我不确定是否正确的方法来执行此操作，它不适用于非八字符的数字。
var a = content.match(/data-seq="(.{8}).*/)[1]
What I need is for the value of a to set all the characters between the quotes after data-seq and not just eight as in the above.
我需要的是a的值来设置data-seq之后的引号之间的所有字符，而不是如上所述的八个。

This is how I would implement it:
这是我实现它的方式：
var a = content.match(/data-seq="([^"]+)"/)[1]
This will capture everything between the double quotes.
这将捕获双引号之间的所有内容。

var a = content.match(/data-seq="([^"][a-zA-Z\-0-9]{3,4,8})"/)[1]
to match only digits or letters (between quotes), precisely 3,4 or 8 chars.
仅匹配数字或字母（引号之间），恰好3,4或8个字符。
