Text field of compensation

Hello

I have a page where you scan a bar code in a text field submit when enter pressed. If the barcode, there is a report appears showing that record. The bar code should remain in the text field.

My question is if I scan a barcode and the bar code does not exist, and then I analyze another barcode, barcode previous stays and gets appended on the new bar code. How can I erase barcodes out of the text field when I scan in a new barcode?

Hello

Add something like the following in the Footer area of the region of report parameter:

<script type="text/javascript">
if (#ROWS_FETCHED# == 0)
{
 $x("P36_BARCODE").value = "";
}
</script>

Replace P36_BARCODE with the actual name of the barcode field.

#ROWS_FETCHED # is filled with the number of lines displayed on the page of the report. If it is 0 (zero), then the script will be executed, and the field is cleared.

    Hello

    What I'm trying to do:

    I'm trying to do textfield1_txt & textfield2_txt clear, once the Send button is released.

    ---

    A description of my Flash file is as follows:

    I have 2 text fields on my Flash stage:
    -textfield1_txt
    -textfield2_txt

    I also have a film clip that I'm using for the Send button:

    Please note that currently, once the submit_mc is out, my ActionScript has a function that checks to ensure that a data type is present in the boxes and submit the form. If errors occur, an error message displays currently:

    Please enter the information in textfield1_txt
    Please enter the information in textfield2_txt

    Can someone tell me please in the right direction to clear text on the output of the submit_mc field?

  • How to get back to 3 text fields in the footer

    When you open a new document pages, the footer contains three default text fields.  I have a document where I removed somehow 2 3 fields foot leaving only 1. I would like to add the other 2 fields in the footer, but I am unable to find a setting that would let me. My search terms are apparently useless because I can't find any thread on point in a search. Any ideas?

    You can not remove the tripartite fields in a header or a footer. If you visit the view menu: display invisible characters, you will probably discover tabs or spaces that forced each cell to the right in your footer. Just remove these external characteristics and you will restore the three cells to your footer.

  • Magento text fields appear as white

    I've recently updated Firefox to version 11.

    When you work in Magento CMS, certain text fields are projected as empty, as if the data was lost.

    Once you take the lower right and make the bigger field, the text is displayed.

    Has anyone seen this problem and is there a solution?

    Thanks in advance

    11 Firefox introduces a problem with TinyMCE WYSIWYG/rich text editor. I wonder if this or a related issue affects Magento?

    You can try an another workaround: zoom a not upward and down a step and see if it causes the text to appear. (You can use Ctrl + Ctrl + - or Ctrl + mousewheel for this.)

  • Cursor will not appear in the text fields, Google Street View mouseup does not

    My wife and I have almost identical computers and update of Firefox, whenever a new version comes out.
    Lately, only on his computer, when it clicks in the address bar or in a text field, the cursor sometimes does not appear. In other text fields, it appears. In the address bar, whenever you click on it, and then type, there is no cursor, and the entire address bar is always overwritten.
    In Google Street View (I think he uses the Flash Player), she can begin to drag, but then "won't let go"-it's as if the mouse to the top of command is ignored. I have to drag the mouse away from the area of the image, then again, or slide it will continue.

  • By assigning a value to a text field not working PHP/javascript?

    I have a site to someone else coded, where a text field does a value that is assigned.

    Both
    Form1.textfield3.value = form1.textfield1.value;
    and
    Form1.textfield3.value = "99";

    not work, and the field is left blank.

    This same code works on Internet Explore (Win and OSX), Safari, Chrome and Opera. It does NOT work on Firefox 8 or 9.01 (Win and OSX) or 3.6.25. He used to work on an older Firefox, we had (unknown version).

    JavaScript is enabled; is there anything else we can check?

    If you check the error in Firefox (Ctrl + Shift + j) Console, you will see "form1 is not defined. This is because Firefox converts automatically form1 in reference to < form = "form1" name >. Instead, you must change the code a bit.

    You can fix the above error starting each function where you refer to form1 with this:

    Form1 = return ["form1"] var;

    However, probably just move the error to the next part of the notation (for example, textfield3). The proper way to refer to the value of a form field named is:

    document. Forms ["Form1"]. Items ["textfield3"]. Value

    or if you have set form1,

    Form1.elements ['textfield3'] .value

    If you have a few changes to make. Not sure if there are shortcuts.

  • Slider custom text field (Cap) does not appear

    All;

    I created a custom text field based on the standard text field, changes work fine (really just a custom height and width and a border).  The problem is the method of painting which seems to remove the cap of the field when it gets the focus.  To be clear the carret never shown at all.

    public class CustomText extends TextField //cutom text field width
    {
        //Custom Height and Width in Pixels
        final static int textwidth=125;
        final static int textheight=25;
    
         CustomText()
         {
         super(); // Call the default constructor    
    
         //Border for text fields
         XYEdges padding = new XYEdges(5, 5, 5, 5); //space between box and border
         Border theborder = BorderFactory.createSimpleBorder(padding, Border.STYLE_SOLID);
    
         //Assign the border to the object
         this.setBorder(theborder);
         }
    
         public void onFocus( int direction )
         {
            super.onFocus( direction ); //invoke parent procedure
            invalidate(); //mark for redraw
         }
    
         public void onUnfocus()
         {
        super.onUnfocus(); //invoke parent procedure
        invalidate(); //mark for redraw
         }
    
         //Override the layout with the custom Width and Height
         protected void layout(int width, int height)
         {
            super.layout(textwidth,textheight);
            setExtent(textwidth,textheight);
    
         }      
    
        //Override the display message such that no message is displayed when the field is full
        protected void displayFieldFullMessage()
        {
        }
    
        //Override the default paint method to call the super class constructor and then assign the border
        protected void paint(Graphics graphics)
        {
           // int prevColor = graphics.getColor(); //Save Previous Color
            graphics.setBackgroundColor(Color.LIGHTGRAY); // Set to Gray
            graphics.clear(); // Clear for redraw
            super.paint(graphics); //Force Redraw of Object
          //  graphics.setColor(prevColor); //restore for cursor paint
    
        }
    
    };
    

    In the paint in the first and last method lines that are commented out were a soloution that I tried after reading on this subject.  Something along the lines of the restoration of the default color, but unfortunately without success.   Any ideas would be more useful

    Thank you!

    Quick thoughts:

    (a) to remove the requirement to substitute paint by setting the background a Color.LIGHTGRAY using the base class

    (b) you put on the field by using this:

    Super.Layout (TextWidth, TextHeight);

    If you then do the following:

    setExtent (textwidth, textheight);

    you are likely to confuse the field.  If you still want to use the entire height and use the full width and then try to deal with it in the Style, that is, replace this:

    Super(); Call the default constructor

    with this

    Super(TextField.USE_ALL_HEIGHT |) TextField.USE_ALL_WIDTH); Call the default constructor

    (c) why you override onFocus and onUnfocus?  I would like to delete these if you do not have anything specific to these methods.

    Make these changes, and you'll have a more simple TextField.  See if these changes will solve the problem of the caret too.

  • How to make a text field so that if a user enters a lower case A, we make a capital?

  • Problem of text selection in the text field for entry in the emulator

    I'm having a problem of text selection in a text field when I run my application in the emulator Playbook. Let me see if I can expose the problem here:

    1. The field in question is a classic text, text with an integrated in police entry field. The domain is in a SWC and referenced in another FILE.
    2. The code is set up such that when a user clicks the field function is called to highlight all the text. The code is more or less as follows:
    thisField.addEventListener(MouseEvent.CLICK, onFieldClick);
    
    private function onFieldClick(event:MouseEvent):void
    {
       var selectedField:TextField = event.target as TextField;
       selectedField.setSelection(0, selectedField.text.length);
    }
    

    The problem I'm having is that when I try clicking on the emulator, the text field in 'domain' is sometimes selected as expected, sometimes not. When the text is not selected as expected the cursor always appears in the field and the Playbook keyboard slides up by below. What is particularly problematic, that's what often happens, is that the whole scene moves upward on 10px when it is clicked on the ground. If I try to click on the same ground once again, another change to the top of 10px or so, etc..

    So why the text not properly selected and why the scene evolves upwards?

    I realize that more information may be required from me to correctly solve this problem, but if someone has all understand why this may be the case, I would be happy to learn from him.

    Thank you

    David

    I can answer the question of displacement.  This is a bug in BB and supposed to be fixed in version «next» SDK

    The question of the selection, I'll guess has to do with the fileld with focus, selection is not possible.  Try to set the focus outside of maybe the text field?
