hello everyone,

ok here is my problem. i have a java servlet wherein it has a StringBuffer that appends my html tags and a javascript. My question is that is there a way wherein i can append a javascript in the StringBuffer using response.setContentType("text/html")? oris there another way to append a javascript in java to be flushed in html?
below is a sample script i made.

StringBuffer buff = new StringBuffer();

buff.append("<p>just some text here..</p>");
buff.append("<script \"text/javascript\">callFunction();</script>");

response.setContentType("text/html");
response.getWriter().println(buff.toString());
response.getWriter().flush();

whenever i execute this program it outputs the html part but does not execute the javascript part.

thanks

Sorry if this is incorrect, but it seems correct on the surface... you appear to have missed part of the tag out where the script begins...

<script \"text/javascript\"...

is what you put,

but surely it should say

<script language=\"text/javascript\"...

?

or "type" if not language. but basically you're missing the equals and the wotsit thingy that is either "language" or "type" in this instance... is my guess, anyway.

Probably just a careless error on your part, eh? Or maybe that makes no difference and it is permissable to write the script tag in the way you've done it - i haven't looked this up, I just made this guess from looking at your code.


this google search appears to corroborate my theory to some extent...
http://www.google.co.uk/search?hl=en...G=Search&meta=

and suggests that "type" is the (more?) correct wotsit to use for this job.

actually, <script language="text/javascript"> would be incorrect, <script type="text/javascript"> would be correct. When the language attribute is used, it is just <script language="javascript"> The language attribute is being phased out though, in favor of type.

I had come to suspect this.

hi guys thanks for the replies,

oops! sorry for the code. careless me..

well, even though i put it this way

buff.append("<script type='text/javascript'>callFunction();</script>");
buff.append("<script type=\"text/javascript\">callFunction();</script>");

or even this way

buff.append("<script>callFunction();</script>");

it still doesn't call the "callFunction" script and execute it.

so, anymore ideas guys?

thanks

javascript has to be triggered by an clientside event, your servlet pushing data onto the page that is already been processed by the browser isn't going to raise an event.
