This article describes the method of JavaScript using RegExp for regular matching. Share it for your reference. The specific implementation method is 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");
// Equivalent to myReg = /d(b+)(d)/ig; myArray = ("ecDBDsdbbdz"); // ecdbBdbsdbbdz
("Regular Expression String: " + );
("Is global? " + );
("Ignore case? " + );
("Is mulitiline? " + );
("------------------------------------------------");
logInfo(myArray, myRe);
myArray = ("ecDBDsdbbdz");
logInfo(myArray, myRe);
function logInfo(myArray, myRe) {
matchedTimes++;
("This is " + matchedTimes + " times match");
("Original String: " + );
("Match Result Array: [" + myArray + "]");
("The 0-based index of the match in the string: " + );
("The last matched characters: " + myArray[0]);
("The parenthesized substring matches [1]: " + myArray[1]);
("The parenthesized substring matches [2]: " + myArray[2]);
("The index at which to start the next match: " + );
("-----------------------------------------------");
}
myRe2 = /^\w+(\d*)$/ig
("myRe2: " + );
//("myRe2 matches abc1? " + ("abc1"));
// Add this line to see the results. Because it is a global match, lastIndex will change. //So the following ("abc") is of course false ("myRe2 matches abc? " + ("abc"));
</script>
I hope this article will be helpful to everyone's JavaScript programming.
