javascript - JS Timer with setTimeout get a "Uncaught SyntaxError: Unexpected token (" -

-

i've been trying make javascript timer using settimeout() command. when @ in browser console returns "uncaught syntaxerror: unexpected token (".

also can see code here: http://mathiakiaer.site88.net/timer/

this html code:

<!doctype html> <html>     <head>         <title>timer</title>         <link rel="stylesheet" type="text/css" href="style.css">         <script src="script.js" type="text/javascript"></script>         <meta charset="utf-8">         <meta name="viewport" content="width=device-width, initial-scale=1.0">     </head>     <body>         <article>             <p id="timertime"><span id="timertimeminutes">00</span>:<span id="timertimeseconds">00</span></p>             <button id="timerstart" onclick='repeattimer()'>start</button>             <div id="timerchangediv">                 minutes: <input id="timerinputminutes" value="0" type="number" min="0" max="60"><br>                 seconds: <input id="timerinputseconds" value="0" type="number" min="0" max="60"><br>                 <button onclick="settime()">change time</button>             </div>         </article>     </body> </html>

and javascript code:

var seconds=0; var minutes=0; function countdown() {     if(seconds!==0) {         repeattimer();         seconds--;     } else {         if(minutes!==0) {             minutes--;             seconds=59;             repeattimer();         } else {             alert("the timer done");         }     }     refresh(); } function repeattimer() {     settimeout("function() {countdown();}", 1000); } function settime() {     seconds=parseint(document.getelementbyid("timerinputseconds").value);     minutes=parseint(document.getelementbyid("timerinputminutes").value);     document.getelementbyid("timerinputseconds").value=0;     document.getelementbyid("timerinputminutes").value=0;     refresh(); } function refresh() {     if(seconds>9) {         document.getelementbyid("timertimeseconds").innerhtml=seconds;     } else {         var secondsshow="0" + seconds;         document.getelementbyid("timertimeseconds").innerhtml=secondsshow;     }     if(minutes>9) {         document.getelementbyid("timerminutes").innerhtml=minutes;     } else {         var minutesshow="0" + minutes;         document.getelementbyid("timertimeminutes").innerhtml=minutesshow;     } }

first param function not string.

function repeattimer() {     settimeout(function() {countdown()}, 1000); }

or

function repeattimer() {         settimeout(countdown, 1000);     }
