//This example will type an "a" in on each click if you only want it to happen once just tell me <!DOCTYPE html> <html> <head> <title>Page Title</title> <script> function popText() { document.getElementById("demo").innerHTML += "a"; } </script> </head> <body> <textarea id="demo"></textarea> <br /> <button onclick="popText()">Go</button> </body> </html>

try putting them into variables: (declare them outside the click function ) var myArea = document.getElementById("demo"); var appendedText = "a"; then inside the click function do this: myArea.innerHTML += appendedText;
