正则表达式在特定单词之后匹配一个单词

Question

I created a regex for matching a string which could be possibly something like shown below:

then "hello I am here" blah blah

or

then hello blah blah

I am trying to match the word just after then . For above strings the expected outputs are

"hello I am here"   //if the words are in quotes

or

hello

I tried this regex &quot;(\\w*[\\s]*)*&quot;|(?<=\\bthen\\s)(\\w+) , which is working fine online but showing error in firefox. Error

Answer 1

Try

var regex = /then\s*("(.*?)"|(\w*))\s*.*/

function getSomething(string){
    var arr = regex.exec(string);
    console.log(arr);
    return arr.length > 1 ? arr[1] : undefined;
}
