This is a little JavaScript Regex tester, just write your Regex as example "\d" or "\w" and a test string like "123abc". It is more like an example as an real use function, but you can see how it works and handle the matches.
Try it:
Matches: Code:
Matches: Code:
<html>
<script>
function myFunction() {
if(document.getElementById("regex").value == ""){
document.getElementById("result").innerHTML = "No Regex";return(0);
}
var re = RegExp(document.getElementById("regex").value, 'g');
document.getElementById("result").innerHTML =
re.execAll(document.getElementById("text").value);
}
RegExp.prototype.execAll = function(string) {
var match = null;
var matches = new Array();
while (match = this.exec(string)) {
var matchArray = [];
for (i in match) {
if (parseInt(i) == i) {
matchArray.push(match[i]);
}
}
matches.push(matchArray);
}
return matches;
}
</script>
<body>
<textarea id="regex" rows="1" cols="50" onchange="myFunction()" onkeyup="myFunction()" placeholder="Your Regex here..."></textarea>
<br>
<textarea id="text" rows="4" cols="50"onchange="myFunction()" onkeyup="myFunction()" placeholder="Your Text here..."></textarea>
<br>
Matches:
<div id="result"></div>
</body>
</html>
