Cancel the 'action' button after validation JavaScript

Hello. I use JDev/ADF 12 c.

I use JavaScript to validate elements of the ADF, when I click on an af:button. This button has a call to another page in the 'action' property.

I need this 'action' runs only if the validation is good. If, for example, an inputText is empty, I need the button do not go to the other page (do not run 'action').

If validation has said that there is incorrect data, I need the user to stay on the same page (even if I click on this button that "in theory", addressed me to another page).

How can I do? How can I 'Cancel' the 'action' of the button?

Sorry for my English. Thank you.

Hello

but it's the default behavior if you let validation of the frame instead of making your own js. If you have to use JS, add an af:clientListener the button then link the name of the method checkOperateOnValidationSuccess for example. The type must be 'action '. Looks like the JS function signature

function checkOperateOnValidationSuccess (evt) {}

make your posting here

If the validation failed then evt.cancel ();

}

  • When click the "back" button after filling out web form, I can't, a message says that Firefox must send information that will be rpeat any action... Why can I go back?

    My current Firefox is version 9.0.1 update
    "when I click on the"back"button after filling web form or make payment online etc, I can't go back to my homepage, if I press the BACK BUTTON (arrow) a message said.
    "Firefox must send information that will repeat any action (for example, a search or order confirmation) that was carried out earlier.

    I don't want to re - order or repeat the process over. The only thing I can do is to leave Firefox and start again which is very painful.

    Any solution will be appreciated.

    Older Firefox had this coming message in case you have used the back to go to a page that is requested from the server with the POST data specific to a form previously sent.

    You receive an alert to send POST data if you return to a page or refresh a page that was requested in advance from the server by submitting form via a (hidden) MESSAGE form data.

    Firefox can only make sure to get the same page send this POST form.

    Firefox doesn't know what it means shape data, so Firefox asks for confirmation before sending the form data so action can you take to repeat an action and buy another article or post a message once.

    A way to prevent that pop up is not to use the back button, but to open the links on a page that have been requested from a server by sending a MESSAGE form in a new tab (window) with a middle click or a Ctrl + left click.

    Then you can close the tab or window to go back.

  • Can we keep direct action buttons after a signature has been added to a form?

    I have a form with several action buttons... Print, save money, submit (by e-mail), disable this form. However, when the signature is applied to the shape, all these buttons become unusable. Is it possible to keep them alive once the signature has been added to the PDF file?

    Thank you.

    Thanks for the quick response. Just after the announcement of my question, I noticed the possibility of excluding specific items of reading only when the signature field is signed. Nevertheless, thank you very much for getting back to me.

  • Run script .jsx and/or the Actions button in HTML extension?

    Hi all

    I'm quite a novice at things .js, .jsx, and HTML.  I use scripts of JSX one former co-worker created and Photoshop actions for many years.  I looked through and have managed to modify the JSX scripts with a few minor changes, but that's all.  Using the Configurator, I created a custom for use in CS6 Panel.  We are moving finally CC2015 team and I'm the only person in our team who has experience and/or desire to convert compatible with CC 2015 Configurator easily created CS6 bench.  I got all of the HTML developed, interface extension runs within Photoshop and I have the buttons either launch an alert or by creating a new document in Photoshop.  The function of coding was all found code.  Now I need to figure out how to make these buttons work our various actions and some to run our scripts JSX.


    Configurator makes it is easy to select a button and tell it to perform an action or launch an external script file.  Is there an easy way to do this now using actions and JSX files that we have already created?

    And just a reminder, I'm a NEWB, so take it easy on me... if possible. In addition, it is only a sign used internally so I need power to market/sell it.  This is specific to our company of workflow and needs.

    Thank you!

    Make sure they are loaded in photoshop

    Another way is to convert action scripts (I see people often using this tool http://www.tonton-pixel.com/blog/scripts/utility-scripts/convert-actions-file/)

    and run the scripts, you put them on the .jsx file, where they will be evaluated, if you used standard mat and then call them by the name of the function

  • Authenticate when the user clicks on the "back" button after disconnection

    Hi all

    Is there a way that the user can be required to authenticate, if simply disconnected, then click on the back button.

    I have a situation where a user who works on relatively sensitive data disconnects (yeees they should close the browser and all, but they never obey instructions...) and someone else can come around and click on the back button and see it as what he had worked on.

    Is it possible to disable this behavior, or otherwise force a reload/re-authentication.

    Thank you.

    Hello

    You can do this by writing this code in each page of your application

    Write this in the html header:

    
    

    and write it in the Page HTML Body attribute:

    onunload="javascript:history.go(1)";
    

    It will not allow users to go back.

  • Could not find the "stop" button after updating to firefox 8

    I've just updated to Firefox 8 and can't find the "stop" button to stop a website from loading if inadvertently, I hit the enter button too soon. I looked under Customize toolbar, but do not see it. Icons, what i've got are back, forward, address bar, Star, down arrow reload, google search bar, blocker for popups and at home.
    Thank you

    Firefox 4 and newer versions, go, Stop and reload buttons are combined into a single button at the right end of the toolbar URL or address. The button changes depending on the type of activity:

    • green arrow GB when you type in the address bar
    • Red Stop ("X") button while the page is loading
    • Reload (circular arrow) to gray when the page is finished loading.

    There are separate buttons:

    1. Open the Customize the toolbar by clicking the Firefox button > Option > toolbars OR by clicking View > toolbars > customize if using the menu OR bar right click in an empty space on a toolbar and select Customize
    2. While customizing the window is open, Stop and reload buttons will show separate from the address bar and the search bar
    3. While customizing the window is open, drag the buttons anywhere on the Navigation toolbar
      • order Reload-Stop will bring together into a single button
      • order Stop-Reload will remain in separate keys
      • or drag a "separator" in the window customize between Reload-Stop and that they remain separated
    4. Click done at the bottom right of the window customize to finish

    Make sure that you are not running Firefox mode full screen with all the hidden toolbars.

    • Press F11 to toggle mode full screen (file/Firefox > fullscreen)

    If the menu bar is hidden, then press the F10 key or hold down the Alt key, which should make the convening of menu bar.

    Make sure the toolbars like the toolbar 'Navigation' and the 'personal bar' are visible: "view > toolbars".

  • If the action button does not have my document?

    I scanned a document private on my printer using the iPad Printercontrol app, I wanted to send the document to myself, so I went into the menu files, selected the scanned document and instead press the arrow icon (share), I pressed the button share instead. Now, I don't know where the document has been "shared" at. Where exactly is he? I don't see all the settings as to where a document would be shared, whether it's on social media networks, that I have accounts or a location in my network.

    Hey CommandereON,

    I see that you use the PrinterControl application and analysis.  I'm guessing that you pressed the ' share' button at the bottom left of the screen when you try to share your emails.  I just tested this option and this button does not send the document from anywhere.  He shares the file outside the control application printer at the Gallery of the camera itself.  You use the button at the top right to share in places such as social networks and e-mail.

    Hope this helps to clarify your question,

  • where are the action buttons left and right on the touchpad on HP ENVY 17 Quad TouchSmart t

    My new mobile Quad TouchSmart HP ENVY 17 t has a touch pad, but no action left or right buttons.  How can I simulate their action.  Apparently a single tap simulates a left click, but how to do a right click?  How to drag a cell in a worksheet (to copy) using the touchpad?  I may end up using a mouse.

    I believe that this model has a ClickPad, which has no buttons left/right click separate but has left/right click zones where the buttons would normally be. For more information, see use and configure the ClickPad .
