回答1:

You need to enclose them in a form tag.

<form name="Video" id="search" onsubmit="ln(search.D1.value)">

<select size="1" name="D1">
<option value="nsei" selected>Nifty</option>
<option value="bsen" >Sensex</option>
</select>

<input type="submit" value="Submit" name="B1" />

</Form>

Then, change ln() so that it takes a variable so perhaps try:

<script type="text/javascript">
function ln(vidvar){

tempcell = document.createElement("embed");
tempcell.setAttribute("bgcolor","#dbdbd3");
tempcell.setAttribute("flashvars",
    ("lcId=1169793726234&amp;state="
    +vidvar+
    ";range=1d;indicator=ema(13,34,55)+macd+rsi+stochasticfast;charttype=candlestick;crosshair=on;ohlcvalues=0;logscale=on;source=undefined")
    );
<!-- And  so on for the rest of the attributes of the <embed> tag -->   
document.getElementById('looknorth').innerHTML=""
document.getElementById('looknorth').appendChild(tempcell);
  }     
</script>

There might be some bug in this but that's the general idea.
