The first thing you want to do is confirm. Unlike Lotusscript, you cannot use a function in the middle of a script to open the confirm dialog and get the answer. To do this, I recommend using the confirm simple action before going into an execute script simple action.
<xp:button
value="delete"
id="button1"
>
<xp:eventHandler event="onclick" submit="true" refreshMode="complete">
<xp:this.action>
<xp:actionGroup>
<xp:confirm message="Are you certain?"></xp:confirm>
<xp:executeScript
script="#{javascript:doSomething();}"
>
</xp:executeScript>
</xp:actionGroup>
</xp:this.action></xp:eventHandler></xp:button>
EDIT
In the past, I have also used built my own dialogs with the extension library, filled the text in with SSJS and then called the doWhatever() or close() from the dialog itself. This is not the best solution as it requires an update from the server to get the string. The best solution would be, as Paul Withers says, to use CSJS to perform the confirmation. I have yet to do this though.
/EDIT
For your delete function, I recommend getting the document you want to delete, then tell whether it is a P- or C- doc, either by the form name or whatever mechanism you use, and then either delete the single document or by getting a documentcollection from the view by using getAllDocumentsBykey(), then iterating through them all, deleting them one by one.
var ky:java.util.Vector = new java.util.Vector();
ky.add("MainCat");
ky.add("subCat");
ky.add("subCat2");
var vw:NotesView = database.getView("vw_myView");
var docs:NotesDocumentCollection = vw.getAllDocumentsByKey(ky);
//... delete stuff...
//dont forget to recycle
Post Question Edit
I recommend the following to get the form name:
var getSelectedDoc = function(){
var vwPnl = getComponent("viewpanel");
var ids = vwPnl.getSelectedIds();
var id = null;
var doc:NotesDocument = null;
if(ids.length > 0){ //could use for loop var i = 0; i < ids.length;i++
id = ids[0]; //could pack all ids into java.util.ArrayList and return that list to work on further
//be warned that if the user selects a parent doc and those automatically deleted by it that you need a mechanism to check if the document was already deleted!
}
if(id != null){
doc = database.getDocumentByID(id);
}
return doc;
}
var doc = getSelectedDoc();
var formName = (doc == null)? null : doc.getItemValueString("form");
if(PDOC_FORM_NAME.equalsIgnoreCase(formName)){
deleteFunctionComplete(doc);
} else if (CDOC_FORM_NAME.equalsIgnoreCase(formName)){
deleteFunctionTwo(doc);
} else {
// uh-oh
}
this also allows you to have the document in case you want to delete it right away.
Edits for comments
If Cdoc should delete more than one document, then yes. You should be using the getAllDocumentsBykey keeping in mind that the view needs to be built for it. By that I mean if you have a view with one single category, there is no issue, just plug in the string and you are fine. If you have a view with three categories, you cannot feed a vector into the getalldocs function with only two values, it must be all three. So, you want to delete all for "mycomp" with the underlying pdocs "Greg" "Sally "Bob", just use alldocsbykey("mycomp"), if the view looks like:
mycomp
---Greg
---Sally
---Bob
but if the view looks like
Poland
---mycomp
------Greg
------Sally
------Bob
then the a vector with poland and mycomp must be used. "poland" does not get the correct documents. --just an fyi and pitfall that is sometimes had.
Edit after further question clarification
I prefer this loop style to remove docs
var doc_temp:NotesDocument = null;
var doc_toDelete:NotesDocument = null;
var coll_docs:NotesDocumentCollection = ...; //get document collection
var doc_nextDoc = coll_docs.getFirstDocument();
while(doc_nextDoc != null){
doc_temp = doc_nextDoc; //set document to delete
doc_nextDoc = coll_docs.getNextDocument(doc_nextDoc); // set next document before deletion
try{
doc_temp.remove(true);//lots of errors can happen here, such as ACL settings
} catch(e) {
//handle, or just break
} finally{
if(doc_temp != null) try{doc_temp.recycle()} catch(e){}// try to recycle, could also cause errors
doc_temp = null;// for the sense of completeness
}
}
Even further edit based on the question edits
of course you are only deleting one Pdoc, the way you have that set up, you are only ever returning one document. You could expand the getSelectedDoc() to put all selected documents into an java.util.ArrayList or something, and then use that arraylist to delete more than one at a time, but that could be dangerous depending on what you do because NotesDocuments are not serialisable. In that case, I recommend using the same code that you use for getSelected doc, use a for loop to get the document IDs, get the document, if the document is not null, then delete.
apropos getAllDocumentsByKey(with a vector)
The way this is currently set up, no Vector is necessary.
If you have a view with a category and sub category and you want to get all the documents in that sub category, then you must use a vector to get at it. If you include a simple string or a vector with only one value, then the documents in the sub category will not be returned. The vector can be thought of as "cat1", "subcat", "furtherSubCat"
Furthermore, there is no check here to see if the string returned from the document is empty. This should be done. There is also no check to see if the DocumentCollection is empty. This should also be done. My expectation is that there is an issue retrieving the collection based on above mentioned reasons.
