How to use elements in .css file with javascript in the jsp

I have a jsp in which i need to show some links with the background colour.The links depends on certain conditions which is known.But the requirement is that the background color should be grey and white alternatively. I could have hardcoded the background color with the link. But the problem is that all the links are not visible to all users. The background color is defined in the .css file. I need to check the background color for the previous link. I am declaring a boolean within a jsp and then verifying the value of that boolean( in the javascript within the same jsp) so that i could know the bckground color for previous link.but i am not able to use the element in the .css element in that javascript which is having if-else loop.It's showing an error when i tried doing this. So can some one help me out how can this be done.

  • How can I load and process an HTML5 file with Javascript in the same way as an XML file?

    I maintain a diary in local weekly files that I am converting to HTML5 from XHTML. I wish to extract all the "articles" about particular topics from these files and display them in different orders. It is possible to load an XHTML file using the loadXMLDoc function described at http://www.w3schools.com/dom/dom_loadxmldoc.asp but the same function detects a parsing error when it reads an HTML5 file. (For example, the parser expects an empty element's tag to end with />). How do I persuade Firefox 16.0.1 to use an appropriate parser?

  • How do you update an .SWF file with Javascript

    Hello - I have this Flash map that I've created. It uses
    javascript calls from within Flash to swap out hidden DIVS when a
    user clicks on a county. When the user clicks on the zip code
    region of that map, a javascript triggers the check box.
    What I need to do now is to have a way that when a user
    unclicks the check box, the zip code region in the map will be
    unhighlighted. Essentially, I need to have javascript tell a movie
    clip within the .SWF file to goto a certain frame and stop.
    I've never done this before, so I'm seeking someone's wisdom
    on how to proceed with this.
    For a visual on what I'm describing, the file can be viewed
    here:

    use the flash'es externalinterface class for two way
    communication between js and actionscript.

  • How to read appended objects from file with ObjectInputStream?

    Hi to everyone. I'm new to Java so my question may look really stupid to most of you but I couldn't fined a solution by myself... I wanted to make an application, something like address book that is storing information about different people. So I decided to make a class that will hold the information for each person (for example: nickname, name, e-mail, web address and so on), then using the ObjectOutputStream the information will be save to a file. If I want to add a new record for a new person I'll simply append it to the already existing file. So far so good but soon I discovered that I can not read the appended objects using ObjectInputStream.
    What I mean is that if I create new file and then in one session save several objects to it using ObjectOutputStream they all will be read with no problem by ObjectInputStream. But after that if in a new session I append new objects they won't be read. The ObjectInputStream will read the objects from the first session after that IOException will be generated and the reading will stop just before the appended objects from the second session.
    The following is just a simple test it's not actual code from the program I was talking about. Instead of objects containing different kind of information I'm using only strings here. To use the program use as arguments in the console "w" to create new file followed by the file name and the strings you want save to the file (as objects). Example: "+w TestFile.obj Thats Just A Test+". Then to read it use "r" (for reading), followed by the file name. Example "+r TestFile.obj+". As a result you'll see that all the strings that are saved in the file can be successfully read back. Then do the same: "+w TestFile.obj Thats Second Test+" and then read again "+r TestFile.obj+". What will happen is that the strings only from the first sessions will be read and the ones from the second session will not.
    I am sorry for making this that long but I couldn't explain it more simple. If someone can give me a solution I'll be happy to hear it! ^.^ I'll also be glad if someone propose different approach of the problem! Here is the code:
    import java.io.*;
    class Fio
         public static void main(String[] args)
              try
                   if (args[0].equals("w"))
                        FileOutputStream fos = new FileOutputStream(args[1], true);
                        ObjectOutputStream oos = new ObjectOutputStream(fos);
                        for (int i = 2; i < args.length ; i++)
                             oos.writeObject(args);
                        fos.close();
                   else if (args[0].equals("r"))
                        FileInputStream fis = new FileInputStream(args[1]);
                        ObjectInputStream ois = new ObjectInputStream(fis);
                        for (int i = 0; i < fis.available(); i++)
                             System.out.println((String)ois.readObject());
                        fis.close();
                   else
                        System.out.println("Wrong args!");
              catch (IndexOutOfBoundsException exc)
                   System.out.println("You must use \"w\" or \"r\" followed by the file name as args!");
              catch (IOException exc)
                   System.out.println("I/O exception appeard!");
              catch (ClassNotFoundException exc)
                   System.out.println("Can not find the needed class");

    How to read appended objects from file with ObjectInputStream? The short answer is you can't.
    The long answer is you can if you put some work into it. The general outline would be to create a file with a format that will allow the storage of multiple streams within it. If you use a RandomAccessFile, you can create a header containing the length. If you use streams, you'll have to use a block protocol. The reason for this is that I don't think ObjectInputStream is guaranteed to read the same number of bytes ObjectOutputStream writes to it (e.g., it could skip ending padding or such).
    Next, you'll need to create an object that can return more InputStream objects, one per stream written to the file.
    Not trivial, but that's how you'd do it.

  • How to get real value from selectOneChoice with javascript?

    Hi,
    How to get real value from selectOneChoice with javascript? The event.getNewValue() only gets me the index of the selected item, not the value/title.
    JSF page:
    <af:resource type="javascript">
    function parseAddress(event)
    alert("new value: " + event.getNewValue());
    </af:resource>
    <af:selectOneChoice label="Location:" value="" id="soc4">
    <af:clientListener type="valueChange" method="parseAddress" />
    <f:selectItems value="#{Person.locations}" id="si7"/>
    </af:selectOneChoice>
    HTML :
    <option title="225 Broadway, New York, NY-10007" selected="" value="0">225 Broadway (Central Office)</option>
    <option title="90 Mark St., New York, NY-10007" value="1">90 Mark St. (Central Office)</option>
    Thanks a lot.

    Something I was missing ,
    You need to add valuePassThru="true" in your <af:selectOneChoice component. I have personally tested it and got the actual value in alert box. I hope this time you got the real solution. You can also test the following code by your end.

  • How do I merge multiple Excel files with more than one tab in each file using PowerQuery?

    Hello
    I have 12 Excel (.xlsx) files and each file has three identically named and ordered tabs in them. 
    I know how to merge multiple Excel files in a folder using M (those guides are all over the web) but how do I merge multiple Excel files with multiple (yet identically named and ordered) tabs? Surely it is possible? I just don't know how to do it in M.
    Cheers
    James

    What Laurence says is correct, and probably the best thing to do when the sheets have differing structures. Here is an alternate approach that works well when the sheets all have the same structure.
    When you first open the Excel file from Power Query, you can see its structure in the navigator at the right-hand-side of the screen. If you select the root (which is the filename itself) and click Edit, you'll see all the tabs in the sheet as a single table.
    You can now do filtering based on the Name, Item and Kind values. When you've reduced the set of things down to the sheets you want, select the Data column and say "Remove Other Columns". If the sheets don't have any header rows, you can just click the expand
    icon in the header and you'll be done.
    Otherwise, if the sheets have headers or if some other kind of sheet-level transformation is required against each sheet before doing a merge, you'll have to write some M code manually. In the following example, each sheet has a header row consisting of
    two columns: Foo and Bar. So the only step I need to perform before merging is to promote the first row into a header. This is done via the Table.TransformColumns operation.
    let
        Source = Excel.Workbook(File.Contents("C:\Users\CurtH\Desktop\Test1.xlsx")),
        RemovedOtherColumns = Table.SelectColumns(Source,{"Data"}),
        PromotedHeaders = Table.TransformColumns(RemovedOtherColumns,{{"Data", each Table.PromoteHeaders(_)}}),
        ExpandData = Table.ExpandTableColumn(PromotedHeaders, "Data", {"Foo", "Bar"}, {"Data.Foo", "Data.Bar"})
    in
        ExpandData

  • How to implement my Own CSS file in Portal App, eg Report

    Hi ...
    I have an urgent problem.
    If i make a report portlet, for example, can i use my own CSS file?
    Where should i put the css file?
    How do i call the css file to the Report Portlet?
    Thanks..
    this is urgent.

    Just two notes.
    1. You're using old 10g (9.0.4.0.1) which soon will be desupported. If this is a running production system then you should update it with patch 9.0.4.2 which you can download from Metalink, and develop a plan to migrate your environment to 10.1.2.0.2. If this is still just a test system, then I recommend migrating to 10.1.2.0.2.
    2. It's not a very good practise calling the Application Server with http://localhost. You should use hostname as described in Installation Guide.

  • How can we load a flat file with very, very long lines into a table?

    Hello:
    We have to load a flat file with OWB. The problem is that each of the lines in the file might be up to 30.000 characters long (up to 1.000 units of information in each line, 30 characters long each)
    Of course, our mapping should insert these units of information as independent rows in a table (1.000 rows, in our example).
    We do not know how to go about it. We usually load flat files using table functions, but we am not sure that they will be able to cope with these huge lines. And how should we pivot those lines? Will the Pivot operator do the trick? Or maybe we should pivot those lines outside the database before loading them?
    We are a bit lost. Any suggestion would be appreciated.
    Regards

    Yes, well, we could define a 1.000 column external table, and then map those 1.000 columns to the Pivot operator… perhaps it would work. But we have been investigating a little bit, and we think that we have found a better solution: there is a unix utility called “fold”. This utility can split our 30.000 character lines in 1.000 lines, 30 characters long each: just what we needed. Then we can load the resulting file using an external table.
    We think this is a much better solution that handling 1.000 columns in the external table and in the Pivot operator.
    Thanks for your help.

  • How do I edit a PDF file with Adobe PDF Pack?

    How do I edit a PDF file with Adobe PDF Pack?

    Well, you don't. Editing a PDF is a difficult and fraught business even with the most expensive software.
    But PDF Pack lets you export to Word; then often you can edit in Word. Now you can make a new PDF. It might look like the original, or it might not. If small changes matter you might be out of luck. ON NO ACCOUNT USE THIS FOR GOVERNMENT FORMS.

  • Does anyone know how to use pages so you can export pdfs from the internet and automatically drag words from the document into the file name of the pdf (i.e., author, title of a scientific paper)

    Does anyone know how to use pages so you can export pdfs from the internet and automatically drag words from the document into the file name of the pdf (i.e., author, title of a scientific paper). For example, if I am downloading a paper by smith called "Surgery" that was published in 2002, it will automatically set the file name in the download to smith- surgery 2002. I have heard pages is smart enough to do this.
    thank you

    Pages can export only its own documents. They may be exported as PDF, MS Word, RTF or Text files.
    Pages can import (ie. Open a file as, or Insert a file into, a Pages document) documents in several formats, but won't rename the document as you describe. Documents that can be Opened (eg. Text, AppleWorks 6 WP, MS Word files) are converted to Pages documents, and retain their original names, with .pages replacing the original file extension. Files that can be Inserted (generally .jpg, .pdf and other image files) become part of the existing Pages file and lose their names.
    It may be possible, using AppleScript, to extract the text you want and to Save a Pages file using that text as the filename, but that would depend in part on being able to identify which text is wanted and which is not.
    How will the script determine where the author's name begins and where it ends?
    How will the script recognize the beginning and of the title, an decide how much of the title to use in the filename?
    How will the script recognize the year of publication?
    For papers published in a specific journal, with a strict format for placing each of these pieces on information, or containing the needed information as searchable meta data in the file, this might be possible. But it would require knowledge of the structure of these files, and would probably handle only papers published in a specific journal or set of journals.
    Outside my field of knowledge, but there are some talented scripters around here who might want to take a closer look.
    Best of luck.
