这是我想出的：
// Finds starting and ending positions of quoted text// in double or single quotes with escape char support like " 'var str = "this is a "quoted" string as you can 'read'";var patt = /'((?:\.|[^'])*)'|"((?:\.|[^"])*)"/igm;while (match = patt.exec(str)) { console.log(match.index + ' ' + patt.lastIndex);}
