Question

I am trying to read binary data in javascript. I got one BinaryReader.js on net. I copied that file where Default.aspx is. If I write the code like following then project got build and running but handshake is not getting done. If I remove src=”BinaryReader.js” then handshake is getting done properly. So my question is, Can I use external script along with my script in same asp.net page? If yes then what am i doing wrong?

<script src="BinaryReader.js" language="javascript" type = "text/javascript">
    var ws;
    function btnConnectSend_onclick() {
        if ("WebSocket" in window) {
            ws = new WebSocket("ws://localhost:35000/");
            ws.onopen = function() {
                alert("Connection Open......");
            };
            ws.onmessage = function(evt) {
                var reader = new BinaryReader(evt.data);
                var tag = reader.readString(26);
                //var txt = document.createTextNode(evt.data.toString());
                form1.txtMessage.appendChild(tag);
            };
            ws.onclose = function() {
                alert("Socket Closed!!!");
            };

            ws.onerror = function() {
                alert("WTF!");
            };
        }
    }

    function btnClose_onclick() {
        ws.close();
    };

</script>

No, you have to create a separate script block for your code, or put it in the script file.

<script src="BinaryReader.js" language="javascript" type = "text/javascript"></script>
<script language="javascript" type = "text/javascript">
    var ws;
    function btnConnectSend_onclick() {
        if ("WebSocket" in window) {
            ws = new WebSocket("ws://localhost:35000/");
            ws.onopen = function() {
                alert("Connection Open......");
            };
            ws.onmessage = function(evt) {
                var reader = new BinaryReader(evt.data);
                var tag = reader.readString(26);
                //var txt = document.createTextNode(evt.data.toString());
                form1.txtMessage.appendChild(tag);
            };
            ws.onclose = function() {
                alert("Socket Closed!!!");
            };

            ws.onerror = function() {
                alert("WTF!");
            };
        }
    }

    function btnClose_onclick() {
        ws.close();
    };

</script>
