JavaScript 正则表达式匹配

Question

我有一些变量

var jdbcurl="jdbc:oracle:thin:%2F%2Finnova:1521%3BServiceName%3Dorcl%3BMaxPooledStatements%3D20%3BCatalogOptions%3D0%3BBatchPerformanceWorkaround%3Dtrue"

alert(jdbcurl.match(/:[\d]+/));    //gives me :1521

如何从 中获取 jdbc:oracle:thin、innova、1521 和 orcl >jdbcurl 变种？

Answer 1

var jdbcurl="jdbc:oracle:thin:%2F%2Finnova:1521%3BServiceName%3Dorcl%3BMaxPooledStatements%3D20%3BCatalogOptions%3D0%3BBatchPerformanceWorkaround%3Dtrue"
var myregex = /([a-z:]+):%2F%2F([a-z]+):(\d+)%3BServiceName%3D([a-z]+)%3BMaxPooledStatements%3D20%3BCatalogOptions%3D0%3BBatchPerformanceWorkaround%3Dtrue/
var matches = myregex.exec(jdbcurl);
// jdbc:oracle:thin is in matches[1], innova is in matches[2], 1521 is in matches[3], and orcl is in matches[4]
