this is wrong. because as far as I know, a struts tag's atrribute sholud not
be filled with mixed stuff by jsp codes and plain text.

if you write this way:

I guess  the error won't occur.

That's a good option too.

FYI, I have experienced some problems with custom attributes on objects in
some browsers.  I suggest always using setAttribute()/getAttribute when
working with custom attributes.  Seems to be more cross-browser-friendly
at this point.

Or generate the target location in JSP like this:


  var mytarget = 


Then look up for target in your main Javascript function. I guess it
would be easier to "attach" target to some well-know object like
window, for example:   window.mytarget = 

I am not a Javascript pro, but you get the idea.

RE: struts and javascript

[Frank W. Zammetti]

The JS file is retrieved by the browser after the page loads and is not 
processed on the server, so the  tag will not be interpreted.

Either leave the script in the JSP as you mentioned, or include it in the JSP 
via server-side JSP include, or configure you web/app server to run .js files 
through the JSP processor.

Subject: struts and javascript

In a JS file I created a function as below.

function showPopup(htmlRewrite) {
var w = 480, h = 340;

if (document.all || document.layers) {
w = screen.availWidth;
h = screen.availHeight;
}

var popW = 200, popH = 100;
var leftPos = (w-popW)/2, topPos = (h-popH)/2;

window.open( 'htmlRewrite', "", "resizable, toolbar=yes, statusbar=yes, 
menubar=yes, status=yes, location=yes, scrollbars=yes", 'width=' + popW + 
',height=' + popH + ',top=' + topPos + ',left=' + leftPos);
}

But getting error at the select statement below. how to call the above 
function??

Was working fine when I had the js function in the jsp itself. i.e it was 
working fine with below code

function showPopup() {
var w = 480, h = 340;

if (document.all || document.layers) {
w = screen.availWidth;
h = screen.availHeight;
}

var popW = 200, popH = 100;
var leftPos = (w-popW)/2, topPos = (h-popH)/2;

window.open('', "", "resizable, 
toolbar=yes, statusbar=yes, menubar=yes, status=yes, location=yes, 
scrollbars=yes", 'width=' + popW + ',height=' + popH + ',top=' + topPos + 
',left=' + leftPos);
}









But now trying to have a common function in the js file and pass an argument 
for the url it has to go to.

what's is the right way of doing this?

Thanks.

In my JSP, have to use the defined variable in javascript. How can I

var totalObj = document.getElementById("total");


Wow, that's so far off I'm not even sure where to start. Marked OT 
because this has more to do with a fundamental misunderstanding of how 
webapps work than anything struts-ish.


JavaScript is run client-side, Struts tags (or any other, for that 
matter) are run server-side. This sounds familiar; did we have a go at 
this once before?


You _could_ do something like (syntax probably wrong; working with other 
technology today):


var total = ;
total += whatever;

and then reference 'total' with a javascript chunk or via any number of 
element replacement techniques on the page.


Does that help?
