Need help with Java script calling an html page
Hello -
I have a bunch of web pages, that call a java script called "header.js". The "header.js" puts a header on the top of each web page. In the Java script, I have a gif (picture) that displays a logo and if you click on it, it will send to you a different website.
I'd like to replace this gif with an actual web page. So, the "header" would actually be a web page and not some gif.
Below is a snippet of the code and I'd like to replace the highlighted section with a web page called "header.html". I don't even know if this is possible.
Can anyone tell me what I need to do? I know pretty much nothing about Javascripting so please be as detailed as you can. Thanks!
/* Common header across all pages... */
document.write(' <div id="header" class="clearfix">');
document.write(' <div id="left" class="float_left">');
document.write(' <div id="logo"><a href="http://www.xyz.com/" onclick="window.open(this.href);return false;" onkeypress="window.open(this.href);return false;" target=_blank><img src="/images/xyz.gif" width="105" height="75" alt="" border="0" /></a></div>');
document.write(' <div id="mainNav" class="clearfix"> ');
document.write(' <ul>');
//document.write(' <li id="nav_controls"><a href="controls.html">Controls</a></li>');
document.write(' <li id="nav_motion"><a href="motion.html">Motion</a></li>');
document.write(' <li id="nav_sensor"><a href="sensor.html">Sensor</a></li>');
document.write(' <li id="nav_encoder"><a href="encoder.html">Encoder</a></li>');
document.write(' <li id="nav_system"><a href="system.html">System</a></li>');
//document.write('<!-- <li id="nav_logs"><a href="#">Logs</a></li> -->');
document.write(' </ul>');
document.write(' </div>');
document.write(' </div>');
document.write(' <div id="right" class="float_left">');
document.write(' <div id="controls">');
Well, the problem with this is that I'm not an expert on SSI and I really know nothing about javascripting...so I'm afraid of breaking the whole web site and also having to modify all the web pages that call this header.
I'll have to read up on server side include...cause I don't know much about it.
If I could do what I want with this "header.js", it would be a lot easier.

Need Help With Java Query String
I'm new to Java and I'm passing data via a URL to another page(I'm not using a form). I have been succesfull in decoding the string to return the name value below:
<SCRIPT LANGUAGE="JavaScript">
function decodeSearchString() {
var nameValue = new Array();
var searchStr = unescape(location.search.substring(1));
if (searchStr) {
var formElement = searchStr.split("&");
var tmpArray = new Array();
for (k = 0; k < formElement.length; k++) {
tmpArray = formElement[k].split("=");
nameValue[tmpArray[0]] = tmpArray[1];
return nameValue
var srchData = decodeSearchString();
</SCRIPT>
However, now I need to add the value returned from the above srcipt to the Java script listed below:
<SCRIPT Language="Javascript" SRC="#srchData.link#?open&pID=PAR"> </SCRIPT>
This above script if working will add the HTML from the URL query to the page, but I keep getting a Java Error with this script. Please Help !I assume you are using a JSP page and not just solely doing Javascript. IF you are using JSP, then read on. Otherwise, I can revisit your script.
To obtain the value of the query string, you would use a method call such as:
String strQuery = request.getQueryString()
Or, to get a single parameter off the query string, you can call:
String strSearchData = request.getParameter("paramname");
Or, if you want all the parameters and values instead of just one long string you can call:
Enumeration enumParamNames = request.getParameterNames();
You can use the above enumeration in combination with getParameter() to get the values.
In order to build your script line and add the query string, you would then do something like this:
<SCRIPT Language="Javascript" SRC="#<%=strSearchData%>.link#?open&pID=PAR"> </SCRIPT>
Notice the <%= %> block in the above code.
I hope that is what you were looking for. Your example is somewhat confusing so I may have answered wrong.

So , I edited the ITunes.java as described in the Admin guide.Copied the .class to my cgi folder in the server.I copied the itunesu file from the shell folder of the sample code.I have modified it accordingly.But when I run it in browser(Firefox) as ..../cgi-bin/itunesu it just gives me a blank page.Nothing shows up.I ran the ITunes.java file locally and it generates an HTML output, which I copied and created a new html.After I run this HTML file, it opens my itunes, but again it says page not found and url contains https://www.xxx.edu/cgi-bin/itunesu?destination=xxx.edu where xxx is my institution name.Not sure if I am supposed to display my institution name in forum.
The admin guide says on page 15 step 4.Copy the itunes.class file and other itunes file to your web server's cgi-bin directory.
I am not quiet sure what does other itunes file mean??
This is how my .java file looks.

Signature 533870b8jshdidk333lfsf6a3143a55c132ec548a4d545bd79322402e8e2596e4
Analysis
The destination string is valid and the corresponding destination item was found.
The identity string is valid and provides the following information:
Display Name my name
Email Address [email protected]
Username mylogin
User Identifier 1243
The credential string is valid and contains the following recognized credential:
1. Administrator@urn:mace:itunesu.com:sites:xxx.edu
The time string is valid and corresponds to 2007-12-03 18:34:33Z.
The signature string is valid.
Access
Because the received signature and time were valid, the received identity and credentials were accepted by iTunes U.
In addition, the following 2 credentials were automatically added by iTunes U:
1. All@urn:mace:itunesu.com:sites:xxx.edu
2. Authenticated@urn:mace:itunesu.com:sites:xxx.edu
With these credentials, you have browsing, downloading, uploading, and editing access to the requested destination.
I am pretty new to this, and working on this for the first time.If someone could guide me through this would be pretty helpful.This is only going to work under IE !
Go to your page template :
Modify the definition, make sur you have this :

ok so i have a midterm and need help this question that is gonna be on the midterm. i dont know how to do it and its worth 16 marks!!!! here it is
the UW Orchestra wants to produce a CD containing all the pieces of music
from its upcoming concert. In order to do that, it needs to calculate the total length of time for the
CD. In addition, the conductor wishes to know which piece of music has the longest duration.
Sample output for the program.
The Swan (3.88)
The Bee (0.98)
Claire de Lune (6.02)
Liebesfreund (3.38)
Ragtime (3.48)
The total time for the CD is 18.74 minutes.
The longest piece is Claire de Lune.
Do not include the HTML that is required to embed the program into a Web page (that is, show
only what you would write between <script> and </script> tags).
[4 marks] In the following space, define a function, Print, that takes two parameters, Title and
Length, and outputs a line of text such that Title appears in italics, followed by Length in
parentheses. The function also returns the value of Length.
For example, Print("My World",30) will output the line
My World (30)
and return the value 30.
Put your JavaScript program for the remainder of this question in the space provided on the next
two pages.
[9 marks]. For each piece of music, your program should input the title of the piece and the
duration (in minutes) for that piece, and it should output a line showing those values using the
Print function just defined. After all pieces have been listed, the program should output the
total length of time for the CD, adding in 0.25 minutes between each piece of music (which is
needed on the CD to separate the pieces).
[3 marks] The program should also output the name of the piece that has the longest playing
time.
Use reasonable variable names, indentation and good programming style. Documentation and
comments are not required, but you may add them to explain any assumptions you might want to
make. You need not check that the input is valid, and you may assume that no two pieces have the
same duration.
can anyone help me out! i would be indebt of ur kindness if u can help me out!This forum is for Java, not JavaScript. The two have nothing to do with each other.
And anyway, this is your studying, so you should try to do it, put forth your best effort, and ask specific questions (on the proper fourm). -

Sreaming at the top of my lungs for HELP with Java Script problem!
Hello,
I have this strange problem that no one seems to know why or how to fix it.Whenever I encounter a web site that has java scripting for anything pop ups or redirects to url's anything that says java script when I mouse over the link my browsers do nothing.That is for explorer 6.0 beta netscape 4.7 and netscape version 6.I have tried in another forum some suggestions but nothing changed even though I am told nothing is wrong with the java scripting.I used to be able to click java script's with all of these browsers but no longer.That was a few months ago.Now to try something new I tried to see if a new browser would work.I now have the latest version of Opera.It did work but using Opera on some sites limits what I can do so it doesn't solve my problem.Then I tried the Sun JavaHot browser it also worked but limits what I can do on some site's.I have Windows 98 & updated most of my dll's etc & my java is version 2 1.3.1.My java script is enabled in Explorer & netscape's & the security is at a minimum level.Please help me figure out why these other browsers work but the other's do not.I want to edit a web site of mine but I can't because of this problem.I am very frustrated by this and need as detailed help as I can get.Anything of a suggestion would be very much appreciated.But I am also not an expert on the working's of a computer so bear with me.
BrianHi,
Well I am thinking that if anyone could know something about Java script it would be java developers.But anyways I had the previous version of explorer 5.0 & the java didn't work in it either.Now how weird is this,I opened netscape 4.7 today & the java scripts are suddenly working.This has me scratching my head wondering if my computer is possesed by some force beyond my capability to know...????Weird as it seems though the explorer still will not respond to a java script.

Need help with java J2Se 5.0 upgrade 2
Having problems with Java when playing on Pogo, the Vaults of Atlantis. When loading, I am getting a message that says that I need to remove and download again, java. That it is not working correctly. I did that yesterday, 05/27/05 and am still experiencing the problem but only after signing off from Pogo and AOL and then trying to sign back on again later in the day. I have to shutdown my computer and bring it back up again and then I can load the Vaults of Atlantis. I have noticed that when I do sign-off from Pogo and AOL, that my java cup stays on in my deskbar. Is that supposed to be normal or is it supposed to disappear? If it is supposed to disappear, what can I do to fix that problem?
Please, can anyone help?Go here http://www.java.com/en/ and click "Download Now".
If that has problems, click the "Manual Download" link and download the "Windows (Offline Installation)".
If there are problems, review the Help information to resolve. -

Need help with Java programming installation question
Sorry for my lack of knowledge about Java programming, but:....
A while back I thought I had updated my Java Runtime Environment programming. But I now apparently have two programs installed, perhaps through my not handling the installation properly. Those are:
J2SE Runtime Environment 5.0 update 5.0 (a 118MB file)
and:
Java 2 Runtime Environment, SE v 1.4.2_05 (a 108MB file)
Do I need both of these installed? If not, which should I uninstall?
Or, should I just leave it alone, and not worry about it?
Yeah, I don't have much in the way of technical knowledge...
Any help or advice would be appreciated. Thank you.
Bob VanHorstThanks for the feedback. I think I'll do just that. Once in a while I have a problem with Java not bringing up a webcam shot, but when that happens, it seems to be more website based than a general condition.

Need help with java will even pay
I need extreme help. I just don't have time lately to write these programs and I have fallen extremely behind. Basically all I need is to pass this class and right now until I can get some more help I just can't make the deadlines. If someone could help me I will pay you just like a tutor.
Requirements for Lab.
You will need to develop a variety of classes for this lab. Specifically, you need to create:
+1. a "PersonGUI" class that displays fields for a person's: firstName, lastName, identificationNum, and sex.+
+2. a "StudentGUI" class that provides Java components for the entry of: classification (freshman, sophomore, junior, senior, or graduate student), and Checkboxes for (a student being in the Honor's program and/or in the ROTC).+
+3. a "FacultyGUI" class that provides Java components for the entry of: rank (instructor, assistant, associate, or full professor), years of service, and salary.+
+4. a "Statistics" class that, when instantiated, creates an object containing an instance variable for each of the the statistical values outlined below. (Each of these instance variables should be declared to be "private".)+
Your main Lab6 class should provide a means for the user to:
+1. Specify the kind of personal data to be entered (Student or Faculty), and+
+2. Then, depending on the choice made, appropriate fields should be displayed to allow the user to input appropriate information for the type of personal data being entered, and+
+3. Controls that support the following functionality:+
* a "CANCEL" control that will terminate any operation currently being performed and return the user to the "Startup" window.
* a "SAVE" control that will cause the just entered data to be harvested from the graphical user interface and the appropriate statistics to be updated. Note: this function may NOT be performed if any of the student or faculty member data fields have not been filled in.
* a "RESET" control that will erase all information recorded to date (i.e., all summary variables are reset to zero).
* a "CLEAR" control that will erase all fields for the personal data currently being entered.
* and a "DISPLAY TOTALS" control that will display, when pressed, the following data:
+1. For students:+
+1. total number of students entered so far,+
+2. number who are male and number who are female,+
+3. number of freshmen, sophomores, juniors, seniors, and graduate students,+
+4. number of students who are in the Honor's program and number who are in the ROTC.+
+2. For faculty:+
+1. total number of faculty entered so far,+
+2. number who are male and number who are female,+
+3. the name and salary of the highest paid faculty member on campus.+
Your program should validate numeric data to the extent:
+1. no numeric field (id number, years of service, or salary) may be left blank by the user. If done so, the user should be alerted to enter a numeric value.+
+2. when the user enters a "years of service" value for a faculty member - the value entered should be verified to be a valid integer value in the range 1 to 50. If the data entered is outside the valid range or is not a valid integer - your program should reject the value and prompt the user that invalid data has been entered and that a new value is necessary.+
+3. when a faculty salary is entered, verify that it is a floating-point value in the range $35,000 to $200,000. Handle invalid data as described above.+
+4. Similarly, if an invalid integer value is entered for the identification number, the value should be rejected and the user prompted to reenter.+
+5. Information should not be saved, nor should statistical values be updated, until all numeric data has been validated.+
Note -- You will be graded on appropriate use of instance vs. local variables, use of methods, and passing parameters and returning appropriate values.
+1. The 'Statistics" class MUST provide "mutator" and "accessor" methods that are required to access values or to modify the values of any variable. REMEMBER ALL VARIABLES ARE DECLARED TO BE "private"!!+
+2. You should implement methods to verify the data, as detailed above. The methods should return boolean values indicating whether the data is acceptable or not.+Sorry to hear about your problems - lack of time, having fallen behind, imminent failure etc - but none of these are Java problems.
This site deals with Java problems: compiler or runtime behaviour that people can't understand. If you have problems of that sort (and especially if solving those problems would help with the problems you did describe) then post them.
Otherwise you would seem to be in the wrong place. -
Need Help with Java Desktop CP Icon
I just formatted and reinstalled Windows XP Home SP2 and installed the JRE 1.5.0.02.
