javascript - should I add ns_return / ns_respond to my code? -


i new learning tcl , adp ,, ajax code not returning result tcl file though sends request thought maybe should add command response , please assist me below code :

    <html>     <body>     <form action="">      <input value="get time" type="button" onclick="showcurrenttime();" name="gettime">     <div id="result" align="center"></div>     </form>     <script language="javascript">     function showcurrenttime()     { var xmlhttp;  if (window.xmlhttprequest)  {      xmlhttp=new xmlhttprequest();   } xmlhttp.onreadystatechange=function() {     if (xmlhttp.readystate==4 && xmlhttp.status==200)     {         document.getelementbyid("result").innerhtml=xmlhttp.responsetext;     }      xmlhttp.open("get","time.tcl",true);      xmlhttp.send(); }     }     </script>      </body>

please note tcl file working print time , if need add commands ns_return or command ns_respond please add explanation , in advance :)

you might find easier use jquery library in javascript, allows write client-side code more succinctly. (note put links used in javascript in <head> section , pull them in reference aids debugging in complex cases.)

<html> <head>     <script src="jquery.js"></script>     <link id="timer" href="time.tcl" /> </head> <body> <form action="">  <input value="get time" type="button" onclick="showcurrenttime();" name="gettime"> <div id="result" align="center"></div> </form> <script language="javascript"> var timerurl = $("#timer")[0].href; function showcurrenttime() {     $.get(timerurl, function(response) {         $("#result").html(response);     }); } </script> </body>

next, need check content type of response server is. should make sure text/plain if i've understood you're trying in case. if i've read documentation ns_respond right, want like:

ns_respond -type "text/plain" -string [clock format [clock seconds]]

more generally, returning json more useful though want different techniques displaying it.
