How can I call a javascript function from a jsp page. 1

[FreshmenProgrammer]

First off i would like to say thanks for the help!

I was just wondering how I can call a javascript function just from jsp code. for example what line can I put in that code where the **** ***** are.

Thank you

<script language="javascript">
function setValue(val){
	
	document.myForm.buttonValue.value = val;
}
function closeWin(){
	window.close();
}
</script>

if (buttonValue != null && buttonValue.equals("worked")){
   
   ********** document.closeWin(); *************
}

Well, I wouldn't do that personally, because I feel it its a bit messy, but you could do :

<script language="javascript">
function setValue(val){
    
    document.myForm.buttonValue.value = val;
}
function closeWin(){
    window.close();
}
</script>

<%
if (buttonValue != null && buttonValue.equals("worked")){
%>   
   <script language="javascript">document.closeWin();</script>
<%
}
%>

I think that would do it.

Just think that jsp help you to write a html dynamically.
Let 's say there is a jsp page in

http://localhost:8080/myweb/index.jsp

and you browse this site with a browser. If you view the source of that page within browser, it is just a html.
Therefore, jsp can do all the stuffs that html can. (Because jsp file will be translated to html when it is run and reach your browser.)

you can write the default value of JavaScript variable with JSP. you can even write JavaScipt dynamically with jsp.
