javascript正则表达式用分号分隔，除了&

Question

我需要 & 保留在字符串中。

示例:

"Rajagiri School of Engineering & Technology;Indian School of Mines University;"

输出应该是:

['Rajagiri School of Engineering & Technology', 'Indian School of Mines University']

Answer 1

您可以将 replace 与回调一起使用，并丢弃 ; 之前有 & 的结果。

var str = "Rajagiri School of Engineering & Technology;Indian School of Mines University;";

var arr = str.replace(/(&amp)?;/g, function($0, $1) { return $1=="&amp"? $1+";" : "\n";
          }).split("\n").filter(Boolean);

输出:

["Rajagiri School of Engineering & Technology",
 "Indian School of Mines University"]
