User alert registration PDF if the required fields are empty/null

Greetings,

I read a lot of threads on this topic. I'm not trying to force the user to stay in one area or otherwise, be annoyed. I would like to just draw the attention of the user when they record the PDF file if there are mandatory fields have not been completed. The alert message would simply be a reminder polite form before sending.

I use Acrobat Pro XI.

(1) is the other tasks/Set Document Actions / Document will save the right place to use a script in this case?

(2) the script will check each field required name? Or is it possible to reference all the fields requested in the document?

(3) I have seen a few examples like this:

f = getField (event.target.name)

If (f.value.length == 0)

{

f.setFocus)

App.Alert ("this field is required. Please enter a value. »)

}

However there are some problems regarding the closure of the alert dialog box and so on. Can someone provide an example script to help me get started?

Thank you!

Exactly how you check a field is empty depends on what kind of field it is. For text fields, you must get the value of the field as a string and compare it to an empty string, something like:

var val = getField("Text1").valueAsString;

If {(val)

App.Alert ("field is not empty");

}

If there is a default value that needs to be changed, you would compare it to the default value:

var f = getField ("Text1");

var val = f.valueAsString;

If (val! == f.defaultValue) {}

App.Alert ("field value is OK");

}

For checkboxes and radio buttons, you would compare it to the string "Off", which means that none in the group is selected.

For drop-down lists (combo boxes) and list boxes, there is normally a single value selected, so you should get the value and check the default value (or something else) to see if the field is filled in correctly.

You could place the script it, but I usually use a separate button that I encourage the user to click to activate the check box. The problem with the help of her saving the event is that you cannot stop the backup.

The script can loop through all of the fields (and test all zeros required), or you can define an array of domain names to check.

  • Prevent the 'Send Email' dialog box until the required fields are filled

    I am new to JS and fight with a last piece of code.

    I have a form with several fields. I send the form as an attachment to e-mail and need the required fields completed before the form can be sent by e-mail.

    Currently, I have a display alert message if all of the required fields are empty, but if I cancel the box warning, the 'send Email' dialog appears immediately and I can send the form even if the required fields are empty. I want the 'Send Email' box to appear only after completing all the required text boxes.

    The problem seems to be with the if/else line (IF all fields req. are empty, send alert. OTHERWISE open the box "Send email"). What is the best way to write this? Ideally, I would like to alert to list specific areas that are empty. Here is what I have at the moment - but obviously something wrong):

    If (requiredFields.length > 0) {}
    App.Alert (Error);

    } else


    var subject = this.getField("JobNumber").value + '-application form;
    this.mailDoc({)
    cTo: "[email protected]"

    })

    (Using Acrobat XI - thanks in advance!)

    LAST UPDATED 18/12/15

    Talk with someone @ Adobe (through our IT people we actually received a CONF. call w / an Acrobat expert!)

    It turned out to be the word "subject" in our Javascript. The word
    "subject" is a reserved word in newer formats and is read-only in
    Drive.  So we had to redefine the word & read "subject".

    Works great!

  • The required fields are not displayed message when left blank

    Hello

    I set fields as required in the value, the field Type as user entered - required tab. Also, I entered a message in the empty Message field. When the user fills out the form, they are allowed to send the form without fill in the fields.

    Any help is greatly appreciated.

    Thank you

    Use the preSubmit event to check required fields / required before sending...

    Check the wire for ideas below.

    http://forums.Adobe.com/thread/606762?TSTART=0

    Usually, if you use the required field and submit the form, it will display the warning message that the required fields are missing, and continue to submit the form. It is therefore preferable to use the programmatic approach for the control on the form submission.

    When you search for the values of field programmatically, you must set the Type property of the value type as input by the user - option.

  • The button should only VISIBLE if the user has entered all of the required fields?

    Hello

    I have 10 fields in the form, 3 are required/mandatory fields to enter the data. And I also kept a button with caption CHECK THE FIELDS.

    I also kept a 2nd button, say legend is GOOD TO GO (this isn't a SUBMIT button, the two buttons are normalbuttons)

    At the point of HRT, GOOD TO GO button is "hidden"

    Now, say, user forgot to enter the 2 required fields and you press the button CHECK THE FIELDS, guest user 2 times with popup legends field of respect.

    Now user entered in 1 field and forgotten again to enter the data in another area and pressed the button CHECK FIELDS, guest user 1 time with a popup with the caption for field of respect.

    Now, the user entered in this field too, very well and CHECK THE FIELDS button, the user has NOT prompted with a popup.

    BUT at this POINT, I need to see THE/PRESENCE button GOOD TO GO

    Please let me know how can they do it in JavaScript?

    Thank you

    You were absent; After each statement - no need after 'else '. Don't know what you're doing with b? B get used somewhere? Also, I think I've fixed your resolveNode syntax. Give it a try.

    for (var i = 0; i)< myarray.length;="" i++)="">
    If (xfa.resolveNode("VISITORINFO["_+_i_+"]").rawValue == null) {}
    b = xfa.resolveNode ("VISITORINFO [" +     i + "]"). caption.value.text.value;
    x = "BAD";

    App.Alert (x);

    on the other
    {
    If (x! = 'BAD') {}
    x = "GOOD";

    Please let me know how can they do it in JavaScript?

    Thank you

    In the click event of the button CHECK THE FIELDS, you can check if all three need to fields are filled. Therefore, you can do the "Good to Go" button hidden/visible.

    If (reqField1XPath.rawValue! = null & reqField2Xpath.rawValue! = null & reqField3Xpath.rawValue! = null)

    {

    If all three fields are filled as a visible button

    GoodToGoButtonXpath.presence = "visible";

    }

    on the other

    {

    GoodToGoButtonXpath.presence = 'hidden ';

    }

    Where reqField1XPath, reqField2XPath, reqField3XPath, GoodToGoButtonXpath must be the XPath of the field.

  • Programmatic access to the "required" fields

    Hello

    My form does not have a real submit button, so "kept" built-in is not function of the field of no use to me unless I can check by program the.

    So if I do 25 page 1 required fields, I don't want to have such a long statement checking if each has a null value.

    Is there a way I can "check" to see if any mandatory field is null? There may be a way to group fields in a table, or something - but it's beyond my capabilities at this time.  I'd appreciate any help!

    How did you film script to email through button?  By nature, using the button "submit" e-mail or normal button with him present URL like "mailto:[email protected] he should check the required fields are filled.»

    You can also simply put

    XFA. Form.Form1.execValidate ();  on the click event of the button.  This will force a check on required fields. (assuming that form1 is the top most name name in your) hierarchy

    Or as you have suggested more high loop through the fields check that they are required and if they are null.

  • Validate required fields are filled

    I have the job of JavaScript to validate that the required fields are filled. Although emphasis is placed on the field properly, continuous script showing all error messages one after another, forcing the user to click OK on each one until they can fill in the field.

    I'm not sure what I'm doing wrong.

    Hello

    Do you have empty messages to display all of the required fields are not filled and call the validation script before you submit it then, he would show all alerts for the left the fields one by one. It becomes boring.

    Alternatively you can proceed as follows.

    -Wrap the fields within a subform. It depends on you subforms how do you want to sue.

    -In the validation script, you can call each posting of a subform. For example, you can call validation script of the subform-1 which has a lot of areas. If something is leftout then it show error this subform only. After that, if the validation then convinces the validation of the second subform script runs. So it would show alerts one by one, rather than a boring way.

    For ex:

    If (form1. Page1.Page1_subform1.execValidate ())
    {
    If (form1. Page1.Page1_subform2.execValidate ())
    {
    If (form1. Page1.Page1_subform3.execValidate ())
    {
    If (form1. Page3.Pag3_subform1.execValidate ())
    {
    }
    }
    }
          
    }
         
    on the other
    {

    }

    Thank you

  • Message for the required field

    I have created a form in Acrobat (not LiveCycle) with Acrobat X on Windows. The form must be accessible, and I need to alert users when a required field is not filed on.

    I tried to use this code in Action, the blur for the required field:

    f = getField (event.target.name)

    If (f.value.length == 0)

    {

    f.setFocus)

    App.Alert ("this field is required. Please enter a value. »)

    }

    Although the code appear in an alert message, I can't close the alert dialog box, nor can I add that to fill the required field because I can't after the closure of the dialog box.

    Does anyone have a suggestion?

    Furthermore, this line:

    f = getField (event.target.name)

    can be changed to this:

    f = event.target;

    And this:

    If (f.value.length == 0)

    should be replaced by:

    If (f.valueAsString.length == 0)

    or even better:

    If (! f.valueAsString)

    Since some entries from field (for example, numbers, 'true', 'false'), the length of the value property will be indefinite, given that the value property is not a string or an array. The code works since "".length == 0 evaluates to true, and undefined is 0 is false, but it's a little sloppy. "."

  • Explanation of the required field?

    Newby here.  So, I marked my form to have "required fields." But there is no error message when the user ignores the required fields.  Why? They are not "necessary".

    Maybe 'necessary' does not mean what I think it means.  Can you give me an idea of what "required" made reference to in a form?

    Thanks for any help you can provide.

    The "Required" property is validated only when the form is submitted. If

    you want that it is used in a different context, that you will need to use a script to do

    yourself.

  • How can I create a "print" button that will check the required fields before printing?

    For Multi Select Value:

    Replace nom_element with the name of the element in the page, something like P101_LOGIN, etc.
