change src of script tag dynamically

[rama1977]

Hi,

I want to change the path value of src attribute of <script> TAG dynamically so that different data gets displyed.

I have the following code

<script language="Javascript"
var today = new Date();
var time = today.getTime();
if (time%2 == 0)
{
src="http://www.indiaglitz.com/channels/hindi/rss/news_js.asp";
}
else if (time%3 == 0)
{
src="http://www.indiaglitz.com/channels/hindi/rss/news_js.asp";
}
else if (time%5 == 0)
{
src="http://www.indiaglitz.com/channels/telugu/rss/news_js.asp";
}
else if (time%7 == 0)
{
src="http://www.indiaglitz.com/channels/malayalam/rss/news_js.asp";
}
else
{
src="http://www.indiaglitz.com/channels/kannada/rss/news_js.asp"
}
></script>

I am substituting src value dynamically.But it does not change after it is loaded for first time.I think once the data got displayed inorder to do display the new content i have to reload the page.But i do not want to refresh the whole page only the portion where this data gets displayed.

Kindly let me know how i can do it.

Thanks

wow, wow, wow ... what are you doing dude?? It's completely *NOT* HTML *NOR* javascript. You can't do that.

There's another way of doing this.

<script type="text/javascript">
  var scripts = {
    2 : "http://www.indiaglitz.com/channels/hindi/rss/news_js.asp",
    3 : "http://www.indiaglitz.com/channels/hindi/rss/news_js.asp",
    5 : "http://www.indiaglitz.com/channels/telugu/rss/news_js.asp",
    7 : "http://www.indiaglitz.com/channels/malayalam/rss/news_js.asp",
    default : "http://www.indiaglitz.com/channels/kannada/rss/news_js.asp"
  };

  function getCurrent() {
    var time = (new Date()).getTime();
    for(var i in scripts)
      if(time % i === 0)
        return scripts[i];
  }

  function addScript(url) {
    var s = document.createElement("script");
    s.type = "text/javascript";
    s.src = url;
    document.getElementsByTagName("head")[0].appendChild(s);
  }

  addScript(getCurrent());
</script>

This will work... however, the difficulty comes in undoing what was done by the previous script. Perhaps it writes into a set area; in this case, you could clear that area.

  }

Hi,

i have attached the zip file desi.zip.It contains a html file.When the html file is opebed in browser, u can see a section in the bottom riht portion.A section called movie link.

That is the section which has to dynamically change.After a certain period the link will display the specified contents of the url.That is where i have copied the script u have given me.But the link does not change.

I have copied the script just after heading "MOVIEW LINK".

KINDLY LET ME KNOW why it is not working.

Thanks
