socket.send Troubleshooting Javascript websocket send

[XMLnewbi]

I am trying to get Javascript to send a command to the server.

{"op":"addr_sub", "addr":"address"}

The original script I could just type that in to the form replace the address and hit send.

Trying to get it so you can just enter the address and hit send.

I modified the function send() by adding a var address. I set that equal to the input from the form; what used to be msg. And set msg to what I want the script to send the server.

function send(){
  var txt,msg,address;
  txt = $("msg");
  address = txt.value
  msg = ({"op":"addr_sub", "addr":"address"});
  if(!msg){ alert("Message can not be empty"); return; }
  txt.value="";
  txt.focus();
  try{ socket.send(msg); log('Sent: '+msg); } catch(ex){ log(ex); }
}

Im getting the following error.

[Exception... "Component returned failure code: 0x80460001 (NS_ERROR_CANNOT_CONVERT_DATA)" nsresult: "0x80460001 (NS_ERROR_CANNOT_CONVERT_DATA)" location: "JS frame :: XXXXX.POS/POS.php :: send :: line 39" data: no]

This is the original script

function send(){
  var txt,msg;
  txt = $("msg");
  msg = txt.value;
  if(!msg){ alert("Message can not be empty"); return; }
  txt.value="";
  txt.focus();
  try{ socket.send(msg); log('Sent: '+msg); } catch(ex){ log(ex); }
}

Sorry if this is a repost browser froze submitting.

thinking I'm not using the quotes right? I know JavaScript is weird about quotes. I tried /" but was getting syntax errors.

I can post the whole script if needed.

[rnd me]

socket.send(JSON.stringify(msg));

thanks for the reply.

I think im seeing whats going on here. {"op":"addr_sub", "addr":"address"} is a JSON object. correct?

To send it I need to turn it into a string?

I tried just changing try{ JSON.stringify(msg); log('Sent: '+msg); } catch(ex){ log(ex); }
}

And im getting

Sent: [object Object]

I'm reading up on JSON objects.

http://www.w3schools.com/json/json_intro.asp

in the example it uses
var JSONObject=

So I edited my code to

function send(){
  var txt,msg,address,JSONObject;
  var JSONObject = {
  "op":"addr_sub",
  "addr":"address"};  
  txt = $("msg");
  address = txt.value
  msg = JSONObject  
  if(!msg){ alert("Message can not be empty"); return; }
  txt.value="";
  txt.focus();
  try{ socket.send(JSON.stringify(msg)); log('Sent: '+msg); } catch(ex){ log(ex); }
//document.write(msg);
}

Im still getting the silly [object Object] I did a document.write and it shows [object Object] I have no idea where that is coming from

[rnd me]

there's a lot of bugs there, so i just rewrote it

i think you meant to use id selectors, since there is no <msg> tag...

function send(){
  var txt=$("msg"), msg;

  msg = {
     "op" :  "addr_sub",
    "addr":  $("#msg").val() || "no value set..."
  }; 
 

  txt.val("");
  txt.focus();

  socket.send(JSON.stringify(msg)); 
  document.write(  "<pre>" + JSON.stringify(msg, null, "\t")  );
}

hopefully that get's you closer...
