I am recently task with collecting data using a pdf form, some fields in the form are required but not all fields, I have created a submit button and the department will received the form fill out, now the form needs to be reset when submitted. so i add a button to submit the form and then reset it. the problem is that if someone fills the form and hits submit missing a required field then when they hit ok all the fields are being reset and the person needs to start over. Please Advice.
My idea is to gray out the submit button until all the required fields are fill out, no idea how to do this on adobe pro.
Thanks
As you immediately reset the form after submitting (what happens when the submit fails?), greying out or making read-only is a way to go.
Assuming that you did set the required property for the required fields, you could add the following snipped to your Calculation script:
var cnt = 0 ;
for (var i = 0 ; i < this.numFields ; i++) {
var mf = this.getNthFieldName(i) ;
if (mf.type != "button" && mf.type != "signature") {
if (mf.required == true && mf.value == mf.defaultValue) {
cnt++ ;
}
}
}
if (cnt > 0) {
this.getField("mySubmitButton").readonly = true ;
} else {
this.getField("mySubmitButton").readonly = false ;
}
And that should do it.
However, this approach is not very efficient, and for bigger number of fields and just a few required ones, it might be better to create an array of the required field names, and loop through this array instead of all fields.

at the moment i programm a database based Chat System.
The friendlist of every User gets loadet in a TreeView after the login.
means:
After the login I request the names of the useres friends by the following Funktion,
String namesSt[] = get.getUserFriendNameByUserID(currentUserID);
To use the given Names to load them as TreeItem into my Friendlist / TreeRootItem "rootItem"
for (int counter = 0; counter < namesSt.length; counter++) {
System.out.println(namesSt[counter]);
TreeItem<String> item = new TreeItem<String> (namesSt[counter]);
item.addEventHandler(MouseEvent.MOUSE_CLICKED,handler);
rootItem.getChildren().add(item);
}
When I now add my rootItem, I see the Names in the TreeView.
But if I click on a name, the given MouseEventHandler doesn´t get called.
Further I just want to request the text of the Element which trigger the MouseEvent, so that i can submit these name to a spezial funktion.
How can i realice such an MouseEvent?
How is it possible to call it from the dynamicly created TreeItem?
Thank you for any help :)
cheerse

TreeItems represent the data, not the UI component. So they don't generate mouse events. You need to register the mouse listener on the TreeCell. To do this, set a cell factory on the TreeView. The cell factory is a function that creates TreeCells as they are needed. Thus this will work for dynamically added tree items too.
You will need something like this:
TreeView<String> treeView ;
// ...
treeView.setCellFactory( tv -> {
TreeCell<String> cell = new TreeCell<>();
cell.textProperty().bind(cell.itemProperty());
cell.addEventHandler(MouseEvent.MOUSE_CLICKED, event -> {
if (! cell.isEmpty()) {
String value = cell.getItem();
TreeItem<String> treeItem = cell.getTreeItem(); // if needed
// process ...
}
});
return cell ;
}
I have a form that I want to lock for presentation once it is filled out. I know how to make this happen with a button to render the text fields read-only. Now I have a form that involves repeated subforms (added as needed). How can I script a single button so it will work for the objects in all the subforms?
The subforms are iterations of "ItemGroup". I need to make "ItemGroup.Item" and "ItemGroup.ItemRx" read-only, and "ItemGroup.ItemHeader.Button" invisible.
I'm at home, hence untested. Let me know if you bump into trouble.
var sfSom = "<path/somExpression to subform containing ItemGroups>"; var nn, n = xfa.resolveNode(sfSom).nodes;
for (var i = 0; i < n.length; i++) {
nn = n.item(i);
if (nn.name == "ItemGroup" && nn.className == "subform") {
/* change stuff here. Decide if Item and ItemRx should be read-only, calculate or protected. For now, we'll settle for hiding the button: */
nn.ItemHeader.Button.presence = "hidden";
}
}
I have a fillable PDF file. I would like to require that a TextBox has a value when the user saves the PDF document i.e. the value is not blank.
Here is what I tried:
(1) Setting the "Required" field on the "TextBox".
PROBLEM: That didn't do much except color the textbox red.
(2) I tried to use the following code in the "onBlur" event:
f = getField(event.target.name)
if (f.value.length == 0)
{
f.setFocus()
//Optional Message - Comment out the next line to remove
app.alert("This field is required. Please enter a value.")
}
PROBLEM: If the user never clicks this box there is no problem
(3) I tried to use the "Validation" tab and run a custom JavaScript.
PROBLEM: If you don't click on the box there is no validation so it is perfectly happy to leave the textbox blank if the user forgets to fill it in
OK, I am out of ideas... Anyone?
Since you are using Acrobat JavaScript I assume you use a viewer that supports and executes Acrobat JavaScript. In this situation you can set the document's WillSave action to a custom JavaScript action and perform validation here. I'm not sure if you can cancel the save operation but at least you can display an alert if the validation fails.
UPDATE: This script will loop through all the fields and display and alert if the field value is empty.
for ( var i = 0; i < this.numFields; i++) {
var fieldName = this.getNthFieldName(i);
var field = this.getField(fieldName);
if (field.value.length == 0)
{
field.setFocus()
app.alert("Field " + fieldName + " is required. Please enter a value.")
}
}
Put the script in document's Will Save action and it will run every time the user saves the form. In Acrobat you set this in Tools > JavaScript > Set Document Actions and select Document Will Save.
Here's my problem: in my application I have a Dojo EnhancedGrid, backed up by an ItemFileReadStore. The page flow looks like this:
The user selects a value from a selection list.
The item from the list is posted on a server and then the grid is updated with data from the server (don't ask why, this is how it's supposed to work)
The new item is highlighted in the grid.
Now, the first two steps work like a charm; however, the third step gave me some headaches. After the data is successfully POSTed to the server (via dojo.xhrPost() ) the following code runs:
myGrid.store.close();
myGrid._refresh();
myGrid.store.fetch({
onComplete : function(items) {
for ( var i = 0; i < items.length; i++) {
if (items[i].documentType[0].id == documentTypeId) {
var newItemIndex = myGrid.getItemIndex(items[i]);
exportMappingGrid.selection.deselectAll();
exportMappingGrid.selection.addToSelection(newItemIndex);
}
}
}
});
Now, the selection of the grid is updated (i.e. the selection object has a selectedIndex > 0), but visually there's no response, unless I hover the mouse over the "selected" row. If I remove the .deselectAll() line (which I suspected as the culprit) then I sometimes end up with two items selected at once, although the grid selectionMode attribute is set to single.
Any thoughts on this one?
Thanks a lot.
You need to use setSelected(), like so
exportMappingGrid.selection.setSelected(newItemIndex, true);
The second parameter is true to select the row, false to unselect it.
This is what works for me:
grid.selection.clear();
grid.selection.addToSelection(newItemIndex);
grid.selection.getFirstSelected();

I would like to create a pop up welcome message for the new member that's successfully registered.
But I m having problem of finding where should I put the code, I have check the ucp_register.html ,, but I don't think that is the display content after the member successfully registered, can anyone help me please? Thanks
It would likely to be a more robust solution to display the popup on the first time the user is logged in as an activated user -- after registration they may not be activated, or they may close the browser window immediately after registration.
The way to do this would be to add a column (say, user_JBL_seen_message INT to the phpbb_users table in the database, then modify functions.php to check that column:
In functions.php, find:
// The following assigns all _common_ variables that may be used at any point in a template.
Before, add:
if($user->data['is_registered'] && $user->data['is_active'] && !$user->data['is_bot'])
{
if(isset($user->data['user_JBL_seen_message']) && !$user->data['user_JBL_seen_message']))
{
$showPopup = true;
$sql = 'UPDATE ' . USERS_TABLE . ' SET user_JBL_seen_message = 1
WHERE user_id = ' . (int)$user->data['user_id'];
if (!$result = $db->sql_query($sql))
{
return false;
}
}
}
Then, find:
$template->assign_vars(array(
After, add:
'JBL_POPUP' => $showPopup,
Then, you can add the popup HTML code to your overall_header.html template file, where appropriate...
<!-- IF JBL_POPUP -->
.... your HTML popup code here.....
<!-- END IF -->
If you don't want existing users to see the popup, then fill the new column with 1s.
I also agree with Damien's suggestion to use a jQuery UI dialog rather than a popup -- most users' browsers will block popups. However, use jQuery in noconflict mode to avoid conflicts with other mods.
