Hi,
I have cr8ed a javascript function in the head section of a jsp
page.
<!--
function go(theURL) {
alert(theURL);
if (theURL!=null){
window.open(the URL,'popup','sc rollbars=yes,re sizable=yes,wid th=800,h
eight=600');
}
}
//-->
This function receives a url and displays it in the pop up window.
This function is called by the onLoadevent() during the loading of the
page. The parameter passed is obtained using the request attribute in
the foll. manner.
<body text="#003366" onLoad="javascr ipt:go(
<%request.getPa rameter("val"); %>)" >
The alert() function in the javascript method display "unspecifie d"
message in this example.
However, accessing the request attribute and storing it in a string
gives me the required result.
ie. String url = <%request.getPa rameter("val"); %> gets the correct
url.
Just want to know if it is possible to use the request attribute
during the onLoad() event.
cheers
String name=request.ge tParameter("val ");
<a href="javascrip t:go('<%=url %>')">Click to view</a>
<jsp:forward page = "centre1.js p">
<jsp:param name = "val" value="<%= url %>"/>
</jsp:forward>
<%/*response.sendR edirect("centre 1.jsp");*/%> 9  28931

Is it really that difficult to type 'eat' instead of '8'?

Wow! You've now saved a whopping six characters from your abbreviations.
Please write in full.
<body text="#003366" onLoad="javascr ipt:go(
<%request.getPa rameter("val"); %>)" >
The 'javascript:' prefix isn't needed. It's just a label in all but one
browser, and it doesn't matter even in that case most of the time. Remove
it.

You seem to be confused as to what happens when. You don't use request in
a load event. By the time the client sees the page, the server has
substituted the code for a value of some kind, and that is what's used.
This is why showing server-side code is useless. It doesn't actually show
the problem because it has no bearing on client-side execution. It's the
values that *result* from the server-side code that matter.
I suspect that the problem is simply an unquoted value. I haven't used
JSP, but I assume that the code above returns an unquoted string, correct?
If so, just place a single quote before the <% and another after the %>.
If that doesn't help, post what you get when you view the source in the
browser.

It's useful though, since some site-search engines are prevented to index
script blocks through this. A good example is PHPdig.

In that case, do what you probably should be doing, anyway. Move the
script into an external file.

No, that may be what you intend it to do. However, in a lot of browsers it won't do
anything except possibly warn the user a Web page tried to open a new window and the
attempt was captured and suppressed. This list of browsers includes, but isn't
limited to:
IE < 6.0.2900 with the google toolbar, the newest AIM w/popup blocker installed or
any other popup blocker (Window Washer, some Symantec software, Proxomitron, etc)
IE 6.0.2900 in it's default configuration
Any Gecko-based browser (Mozilla, Netscape, Firefox, Camino) in it's default
configuration
Opera 7.54 if configured to "Block unwanted pop-ups" (I haven't bothered to check,
but I'd bet it will start coming configured that way in 7.6)
All these browsers and browser add-ons come with this option because people are sick
of new windows popping up simple because they chose to visit a Web site.
Of course, if this is for an Intranet application, and you control the browsers
used, and their configuration, then by all means continue to open a new window on
page load.

during the onLoad() event.
Sure you can use a server-side request in an onload event:
<% String val = request.getPara meter("val"); %>
<body onload="alert(' <%= val %>');">
As some others have said, it's most likely that you didn't quote the string that
gets returned from request.getPara meter(). In other words, you're doing this:
<% String val = request.getPara meter("val"); %>
<body onload="alert(< %= val %>);">
(note the missing inner single quotation marks on the call to alert())

Sorry, but at the end of the day, typing full words (when one can do
with abbreviations and get the message across)is the last thing on my
mind. hehehehehe!!!!
Aneways, When i use <body text="#003366" onLoad="javascr ipt:go( '<%request.getP arameter("val") ;%>')" >
the source in the browser is
<body text = "#003366" onLoad = "javascript :go( '')" >
and it shows an empty alert box. It also goes on to pop up an empty
window.
<%
String name=request.ge tParameter("val ");
out.println("ur l= "+name);
%>
Using the above statement in the jsp body does return me a proper url
which is printed on the same page.
cheers

Then your problem must be on the server, and not with Javascript.
Ask in the JSP forum on Sun's website. I also believe JSP is on-topic in
one (or possibly more) of the comp.lang.java. * groups.
Good luck,
Mike

Then this app(s) is/are b0rken. It/They should not index script elements
at all (or at least should provide a pref to do so), whether "commented out"
or not.

I'd like the focus to be on "mycontrol" when the page is first loaded. I'm
getting an undefined error and am assuming that I can't do this in the body
ONLOAD event because the control is not yet rendered. (but I thought this
would still work)
<body onload="mycontrol.focus()">
Also, is there a way to not produce an error if that control does not exist?
Thanks!

Hi,
I am wanting to capture an onmousedown event without firing the body tags
onload event.
Also, if anyone could explain why this happens that would be excellent. I
can't see how an onmousedown event could bubble up to an onload event.
NOTE: If you put an alert() statement in the onmousedown event handler the
body onload event doesn't get fired.

Hi everyone,
I'm writing a function (in javascript) that needs to do one thing if
the page has not loaded, and another (different) thing if the page has
already loaded.
I'm looking for a way to tell if the window.onload event has already
fired. I cannot edit the onload event handler itself, and my function
can only exist in an external js file, sourced from the document's
head section. Any ideas?

Hi,
I have an asp.net web application which uses a pop-up form that works a bit
like a dialog box. when the user clicks "OK" it does a postback (basically a
form post if you don't know .net) to save the contents of the form, and then
I put an onload event to do a window.close.
this works fine for hundreds of people on different browsers. However, for
one user the window does not close.

Hello everyone,
I would like to open a child window from the parent, and add an onload
event listener to the child window which will tell the parent when the
document has loaded. As far as I know, this shouldn't be an issue, but
I just can't get it to work. The script only needs to work with
Firefox/Mozilla, so XP code isn't an issue.
I have tried to open a window like so.
