You can use word boundaries \b, the following example shows how to match every word starting with t
var string ="hallo, this is a test john doe .Another tea house pole. Hey Tom."
result = string.match(/(\bt\S+\b)/ig);
//result = string.match(/(\st\S+)/ig); // alternative
document.write(result);

I want to find words which start with a specific letter in a string using the following code. The specific letter would be supplied by the user in a text box.
This is what I have:
<!DOCTYPE html> <html> <body> <input id="srch" type="text" /> <button onClick=searchword()>Search</button> <p id="wrd" > hallo, this is a test john doe . Another tea house pole. </p> </body> <script> function searchword() { var s = document.getElementById("wrd").innerHTML; var p= document.getElementById("srch").value; var regx = new RegExp("(?:^|\W)" + p + "(\w+)(?!\w)","gi"); var re = regx, match, matches = []; while (match = re.exec(s)) { matches.push(match[0]); } alert(matches); } </script> </html>
