JavaScript USES RegExp for regular matching

This article shows how JavaScript USES RegExp for regular matching. Share to everybody for everybody reference. Specific implementation methods are as follows:

<script type="text/javascript">
  var matchedTimes = 0;
  //Match one d followed by one or more b's followed by one d
  //Remember matched b's and the following d
  //Ignore case
  myRe  = new RegExp("d(b+)(d)", "ig");
  //  Is equivalent to  myReg = /d(b+)(d)/ig;
  myArray = myRe.exec("ecDBDsdbbdz"); // ecdbBdbsdbbdz
  console.log("Regular Expression String: " + myRe.source);
  console.log("Is global? " + myRe.global);
  console.log("Ignore case? " + myRe.ignoreCase);
  console.log("Is mulitiline? " + myRe.multiline);
  console.log("------------------------------------------------");
  logInfo(myArray, myRe);
  myArray = myRe.exec("ecDBDsdbbdz");
  logInfo(myArray, myRe);
  function logInfo(myArray, myRe) {
    matchedTimes++;
    console.log("This is " + matchedTimes + " times match");
    console.log("Original String: " + myArray.input);
    console.log("Match Result Array: [" + myArray + "]");
    console.log("The 0-based index of the match in the string: " + myArray.index);
    console.log("The last matched characters: " + myArray[0]);
    console.log("The parenthesized substring matches [1]: " + myArray[1]);
    console.log("The parenthesized substring matches [2]: " + myArray[2]);
    console.log("The index at which to start the next match: " + myRe.lastIndex);
    console.log("-----------------------------------------------");
  }
  myRe2 = /^\w+(\d*)$/ig
  console.log("myRe2: " + myRe2.source);
  //console.log("myRe2 matches abc1? " + myRe2.test("abc1"));
  //  Plus this row running to see what happens, because it's theta global Match, so lastIndex Will change, 
  // So the latter myRe2.test("abc") Is, of course, false
  console.log("myRe2 matches abc? " + myRe2.test("abc"));
</script>
