How the file CSS & JavaScript work in APEX

I'm new to the concept of CSS and Javascript.

I have after the query.

1. I have to set my standard application in terms of font size, color, etc...
What is the best way to do it... should I create a CSS file, and put all my styles out there and then use them in all the
Pages using the entire application.

2. it is by default we have one CSS file for each theme, that is to say CSS file of specific theme or application specific, if I want to
create my own css file it will be ovveride the default. [can we have more than a single css file in an application]

3. How can I see the APEX default CSS file.

4. regarding javascript, where should I define javascript functions, if I use this func in most of the pages with the application.

Someone can also me proven documentation link for - How to use CSS and Javascript in APEX.

Thank you
Deepak

Hello

In fact, I don't know why you use WORKSPACE_IMAGES instead of APP_IMAGES - what is just like that! This does not mean that other applications will automatically get the style sheet, as this would occur only if you have linked to the style sheet in their page designs

Apex javascript and theme css files must be stored in the server your /images/ folder structure. If you use FireFox and the developer toolbar, you can use this to see the contents of the file. There is probably something similar in IE, but I only use too, so not sure what that snap would be ;)

For multiple files, this shouldn't be a problem. For javascript files, the only question would be if you named one of your functions exactly the same as in the scripts of the Apex. In this case, it is likely that the second function would be used. There may also be a small problem with the names of variables (for example, var x ;) set outside the funtion blocks as you cannot set these two times.

For files css, normal css rules apply when there are multiple instances of the same style - see: [http://www.w3.org/TR/CSS2/cascade.html#cascade]

Basically, if you have:

.x {color:red; border:1px solid blue;}

followed by:

.x {color:black; background-color:yellow;}

True style applied the class name 'x' would be:

.x {color:black; background-color:yellow; border:1px solid blue;}

but, if you still want red text, you can override this by updating the first statement above to:

.x {color:red!important; border:1px solid blue;}

so, the result will be:

.x {color:red!important; background-color:yellow; border:1px solid blue;}

Note also that, if the class name of 'x' has been applied to a TD tag, and you have the following style somewhere:

TD {font-size:12pt;}

This would also apply, so the result would be:

.x {font-size:12pt; color:red!important; background-color:yellow; border:1px solid blue;}

This means that if, for example, you used the theme 1 of your application, you can override any of the styles using the style sheet of the theme with one of your own to apply a style to the class a topic 1. Tell him you want to change the style of t1Header of the theme used on a Standard report - you only need to do:

.t1Header {background-color:pink}

It is better not to override the styles that style a tag type (as in the example above of TD) as they apply to all the instances of this type of tag in the page - and this can cause unwanted results. If possible, stay with class names or ID values: for in a style class names, add a point in front of the name (as shown in the examples above for the class 'x'); for the ID values, use the symbol # (for example, #P1_ITEMNAME).

All other styles for t1Header will remain the same and, more important still, you don't have to recreate every single style in the theme just to make this change.

Finally, you can have as many javascript and css files as you wish. Each page template could bind to any of these, if you do not have to include all of them on each page - only those which are necessary for this model.

  • How export/import prefs.js? Copy of the file does not work

    I want to export/import on: configuration changes. The path is "Firefox/Profiles/i63866ho.default-1384517947097/prefs-js". I also copied prefs.js, all the contents of the file "i63866ho.default - 1384517947097" and the folder "Profiles". Nothing has worked. When I copied prefs.js he did nothing and returns to the old/first prefs.js after restarting firefox. When I copy the file it says that it cannot do.

    Can someone help me?

    Thank you very much

    I'm not very familiar with profiles.ini. There are probably other volunteers who can tell you the best way to add the new (old) profile name to the file.

    The prefs.js file is small, but you mentioned the copy of your extensions as well, so I thought it would be more convenient copy the entire folder. I think that if you can afford the disk space, it is easier to grasp this. That said, some of the information is redundant with, for example, the bookmarkbackups folder contains many safeguards dated (mine are over 1 MB). If you use download sites that use IndexedDB (such as the mega), can have a very large folder indexedDB that you really don't need to carry with you.

  • Save the file CSS in DW5 problem

    When mode design in an html page, when I make a change to the CSS using the Panel Styles Css, style sheet shows as not registered (has a * next to it).  When I do a backup of the html file, css file does not save, so to get an accurate preview in the browser, I have to go and save the css file separately.  It is a pain.  How can I register the css file when I save the html file?

    Thank you.

    There is also a file > save all the associated files. This will save all the files that you see for this document, if you don't want to save each open file. Under windows, you can go to edit > keyboard shortcuts to change the binding key if you wish.

    FWIW, if you use LiveView for your preview it loads the stylesheet not saved you can see previews as you work. If you use "Preview in browser", it should invite you to save your CSS file or record a temporary version of it according to your user settings. Maybe these could help instead of save and refresh in the browser.

  • Want the file names to work as captions

    Hello, I am about to create a DVD of photos and music from an audio CD.  I've never used Windows Media Center before, but plan to use for this project.  Before we go too far, I would like to know how to have my file names to display on each photo - as a legend.  And I don't want the file extension that you want to display.  Can someone tell me how to save the pictures correctly for this purpose?  Thank you, Susan

    FastStone Image Viewer freeware can add
    file names in the face of your photos in a batch.

    (FWIW... it's always a good idea to create a system)
    Restore point before installing software or updates)

    FastStone Image Viewer
    http://www.FastStone.org/FSViewerDetail.htm
    (Windows XP / Vista / 7) (on the screen to download...
    try... exe (site 2) for easier downloading)

    I suggest that you create a new folder and add
    copies of your photos for experimental purposes.
    If you are unhappy with the result your originals
    will be intact.

    After FastStone is downloaded and installed...
    Open the program and go...

    Tools / open the Batch Conversion / tab Batch convert...

    Check the box... Use of advanced options...

    Advanced Options button / tab text.
    Check the box... Add text...

    (You will need to experiment with the position and the police
    size and color to get the desired result.)
    (the text size will need to be adjusted according to the)
    the size of the photos)

    Open the window drop... "Insert a Variable."
    choose... The file name / no Extension...
    (in the white field you should see ($C1)
    Left click... Ok

    On the Batch tab convert... in the left field...
    Find and select the photos you want to
    Add.

    Left, click on the Add button to move the files to
    the right field.

    Choose an output Format...

    Choose an output folder...

    Click on the button convert...

    It's much easier to do than to explain then
    give it a try before say you "Good Grief... it's too
    a lot of work.

    BTW... when your photos are ready... try to import
    in creation of Windows DVD to create your video
    slide show.

  • Bug / / eyebrows file does not work in APEX 4.1.1

    Hi guys,.
    I just installed APEX 4.1.1 on Oracle 11 g R2 xe. on the WEB SERVER in Windows Server 2008 computer. with earphone 1.1.3 of the APEX. deployed on Glassfish 3.1.2. and the user Goolge chrome...

    Element browse file does not work... whether on my request (when the value is required), or on request builder.e.g when I tried to import an application:
    I selected the file, then click NEXT, but I get this error:
    1 error has occurred
    File must be selected to download. (Go to error)
    Something to mention, when I installed APEX, I have not download images
    @apxldimg.sql
    and this because I want to work on Glassfish and assume that no need to download the images in the DB...

    Kind regards
    Fateh

    I'm having a similar problem. See the thread "Thread: problem importing Application with Glassfish 4.1.2.

    I think he is Glassfish 3.1.2 related as it works very well in Glassfish 3.1.0 and 3.0.1. For what it's worth I'm on 64-bit RHEL 5.x, so I don't think it's a Windows specific issue either.

  • Change the color of the file with Javascript tag

    I need to be able to run a script JS from Photoshop and when it is complete, change the color of the file in the Finder to indicate that he has been treated.  I want to talk about the red, orange, yellow, highlights etc., you can give the files in the Finder.

    I know how to change these file color in Applescript.  But I can't understand how to start the process of JS by operating inside Photoshop.

    So I was curious to know if there was:

    A. a way to run an AppleScript, JavaScript

    or

    B. a way to set a property of a JS such as the Finder file it would interpret in a colour highlight?

    Any ideas?

  • Animate the file in Captivate works on Mac but not Windows. Why?

    I built a custom ToolTip rollover in edge animate and then imported the .oam file into Captivate. I chose this path because the end result of the lesson of Captivate is HTML5 and bed in Captivate training balloon interaction works with a .swf output. So I wanted the animation fantasy effect

    Here's the thing. The ToolTip works and works beautifully on my Mac when you view the file Captivate output in the browser Chrome or Safari. When you try to view the same Captivate file into Chrome, Firefox or IE on a Windows operating system, it is a complete failure. Why is this? This is important because I'm working on a hybrid team where there is a mix of OS X and Windows operating system, and there is not to say the variety of the OS which will be used to interact with my lessons of Captivate.

    So here's my question: why est-info-bulle works perfectly under OS X, but a complete failure on Windows?

  • How the file integer buffer all streaming

    Hello

    I have a service running on a FMS server and I was wondering how I would get a stream to keep download the rest of the file all streaming. For example, like downloads YouTube full video while you look a little like a progressive download only but I want as my streaming server. How would I go to do this?

    Or even better than that, if I could put in the buffer at least 20 seconds before the current position of the stream. If I use NetStream.setBufferTime (20) - the stream play until at least 20 seconds has been buffered, but I want to make sure he will play even if it has not been buffered completely, but will keep buffering all streaming.
