testing123

我想获得每个字段(Return-path,Date,From,To等)以及正文(testing123) 。

I want to get every field (Return-path, Date, From, To, etc.) as well as the body ("testing123).

我尝试使用匹配:

    var bodyRegex = /[\n]Subject: (.+)[\n](.+)/

但我得到空值。

推荐答案

试试这个:

代码:

//var rePattern = new RegExp(/^Received:(.*)$/);
var rePattern = new RegExp(/^Subject:(.*)$/);

var arrMatches = strText.match(rePattern);

结果:

arrMatches[0] -> Subject: test
arrMatches[1] -> test
