Question

I have a embedded code which displays yahoo chart

the embedded code is –

<embed bgcolor="#dbdbd3" flashvars="lcId=1169793726234&amp;state=symbol%3D%5Ensebank;range=1d;indicator=ema(13,34,55)+macd+rsi+stochasticfast;charttype=candlestick;crosshair=on;ohlcvalues=0;logscale=on;source=undefined" loop="false" menu="false" name="BANKNIFTY" pluginspage="http://www.macromedia.com/go/getflashplayer" src="http://us.js2.yimg.com/us.yimg.com/i/us/fi/yfc/swf/flashchart_1.18.swf" style="height: 775px; width: 550px" type="application/x-shockwave-flash" wmode="opaque"></embed>

I want this embedded code to be displayed when I click on the display button.

Please suggest the relevant javascript.

I tried something like this

<script type="text/javascript">
function ln(){
document.getElementById('looknorth').innerHTML='<embed bgcolor="#dbdbd3" flashvars="lcId=1169793726234&amp;state=symbol%3D%5Ensebank;range=1d;indicator=ema(13,34,55)+macd+rsi+stochasticfast;charttype=candlestick;crosshair=on;ohlcvalues=0;logscale=on;source=undefined" loop="false" menu="false" name="BANKNIFTY" pluginspage="http://www.macromedia.com/go/getflashplayer" src="http://us.js2.yimg.com/us.yimg.com/i/us/fi/yfc/swf/flashchart_1.18.swf" style="height: 775px; width: 550px" type="application/x-shockwave-flash" wmode="opaque"></embed>'();
  }
</script>
<input type=button style="background-color:#123742; color:#FFFFFF ; font-weight:bold; font-size:15" name=Button2 value=Calculate onClick=ln();></td></tr>

by referring to a code found on the internet but is not working.

Answer 1

This line need to be edited:

document.getElementById('looknorth').innerHTML='<embed ....</embed>'();

To:

document.getElementById('looknorth').innerHTML='<embed ....</embed>';

the parantheses are not supposed to be there, because the string is not a function.

Create a div with the said id first then add the content to it:

<div id="looknorth"></div>

<script type="text/javascript">
function ln(){
document.getElementById('looknorth').innerHTML='<embed....></embed>';
  }
</script>
<input type="button" value="Show Chart" onClick="ln();" />
