I'm need to count user input length in simple form.
I'm tried this:
Template.index.created ->
#symbols = new ReactiveVar
#symbols.set($('#whatsnew').val().length)
return
And in template(jade):
//index.jade
.small-9.columns
input(type='text', placeholder='whats new?', name='whatsnew', id='whatsnew')
...
#{sybmols}
...
But this not working
I'm need to count characters of user input. How to make it?
Your code isn't reactive. There's no reason for your ReactiveVar to rerun. You can try adding an event for every onkeyup event in your input field. When this happens you can get the length of the entered text and set it in your symbols ReactiveVar.
Then every reatice context dependent on symbols will rerun.

I have just created a window, containing a fill-in field (TestField) and a checkbox (chk_TestField):
DEFINE VARIABLE TestField AS INTEGER VIEW-AS FILL-IN.
DEFINE VARIABLE chk_TestField AS LOGICAL VIEW_AS TOGGLE-BOX.
It is very simple to change the value of the fill-in field, based on the checking of the checkbox, something like:
ON VALUE-CHANGED OF chk_TestField IN FRAME DEFAULT-FRAME
DO:
TestField = 5.
END.
However, I'm interested in changing an attribute of the Fill-in field itself, not the integer it represents (I would like to make the fill-in field read-only), how to I do this?
I've tried:
ON VALUE-CHANGED OF chk_TestField IN FRAME DEFAULT-FRAME
DO:
TestField.Read-Only = NOT(chk_TestField).
END.
This, obviously, does not work.
ASSIGN TestField:READ-ONLY IN FRAME {&FRAME-NAME} = TRUE.
or
ASSIGN Table.TestField:READ-ONLY IN FRAME {&FRAME-NAME} = TRUE.
I am new to progress 4GL. In my program, I tried to create a form using progress 4GL. The form has two fields one is DB name and another one is DB Description. The scope of this form is by default this should have one DB name and description and if a user-entered or keep blank in the field of DB name then an alert box should give a message. I have developed the form but when I run it the program keeps continuously running and window form goes not responding stage. I don't get a chance to enter or keep blank to the DB field name. Let me share my code and please help to find out what is the issue and why it's continuously running.
define variable cArcDB as character no-undo format "x(20)" INIT "qadb".
define variable cArcDBDesc as character no-undo format "x(25)" INIT "archive database".
define variable cTmp as character NO-UNDO.

/* Find next/prev record from ttAppDB */
cTmp = cArcDB:input-value in frame frArchiveDB.

end.
end. /* editing */
cArcDB = trim(cArcDB).
if cArcDB = "" then do:

next-prompt cArcDB with frame frArchiveDB.

end.
END.
Please have look at the online reference of the "EDITING phrase". To me it looks like you're missing the READKEY after the beginning of the EDITING block and you also need to "APPLY LASTKEY" at some point. See the sample there:
/* Update Customer fields, monitoring each keystroke during the UPDATE */
UPDATE Customer.Name Customer.Address Customer.City Customer.State SKIP
Customer.SalesRep HELP "Use the space bar to select a SalesRep"
WITH 2 COLUMNS EDITING: /* Read a keystroke */
READKEY.
/* If the cursor is in any field except SalesRep, execute the last key
pressed and go on to the next iteration of this EDITING phrase to check
the next key */
IF FRAME-FIELD <> "SalesRep" THEN DO:
APPLY LASTKEY.
IF GO-PENDING THEN LEAVE.
ELSE NEXT.
END.
/* When in the SalesRep field, if the last key pressed was the space bar
then cycle through the sales reps */
IF LASTKEY = KEYCODE(" ") THEN DO:
FIND NEXT SalesRep NO-ERROR.
IF NOT AVAILABLE SalesRep THEN FIND FIRST SalesRep.
DISPLAY SalesRep.SalesRep # Customer.SalesRep.
NEXT.
END.
/* If the user presses any one of a set of keys while in the SalesRep field,
immediately execute that key */
IF LOOKUP(KEYFUNCTION(LASTKEY),
"TAB,BACK-TAB,GO,RETURN,END-ERROR") > 0 THEN APPLY LASTKEY.
ELSE BELL.
END.
I'm going loopy....
I want a date, in date format, for example
21/06/2017 17:23:04 GDT
I stamp this on a document, but I then want to display it on my xpage as:
21/06/2017 17:23
But I keep getting different results no matter what I do. I get the date from the onClick of a button using
var dt = new Date();
I then pass this into a function:
function AddObjectivesHistoryItem(doc, dt, action, username){
var ArrDocHistory:array = doc.getItemValueArray("History");
if(ArrDocHistory.length < 1){
// This should always return an object as it is created when an objectives document is first
// created but do this check to be safe and create an array if for some reason it doesnt exist
ArrDocHistory = [dt+"|"+action+"|"+username];
}else{
// append new value to the array
ArrDocHistory.push(dt+"|"+action+"|"+username);
}
doc.replaceItemValue("History",ArrDocHistory);
doc.replaceItemValue("LastUpdatedByName",username);
doc.replaceItemValue("LastUpdatedDate",dt);
}
I've tried using toLocaleString() and all others it seems but it wont work.
For example, toLocaleString() displays as 13-Mar-2018 15:02:15 on my xpage. It's close to what I want except it uses hyphens instead of slashes, and also displays the seconds.
I've tried using custom date pattern on my date field properties with no luck and I'm certain I'm missing something super obvious!?
Any pointers on how to firstly get the date like 21/06/2017 17:23:04 GDT and store as a date and secondly to then display it as 21/06/2017 17:23, this can be a string if it needs to be.
Thanks
You can get your date value as String in SSJS with:
var dateTimeFormat = new java.text.SimpleDateFormat("dd/MM/yyyy kk:mm");
var dateTimeString = dateTimeFormat.format(dt)));
If you want to store as text, java.text.SimpleDateFormat is best for converting a date server-side to a specific text format. It can also be used in a converter to manipulate to/from as well.
I want to create a lottery skill that takes 6 numbers from the user.
I'm currently learning by going through the samples and developer guides, and I can go through the guides and get a working skill that will take one input and then end the session. But I believe I need to create a dialog somehow, which is where I get stuck.
Design-wise, I'd like the dialog to go like this:
Alexa: Please provide the first number
User: 1
Alexa: and now the second...
User: 2
etc etc
But I think it would be OK if it went like this:
Alexa: Please call out 6 numbers
User: 1, 2, 3, 4, 5, 6.
Is this even possible? Will I have to create a custom slot type called "Numbers" and then put in the numbers, eg 1-50 or whatever the limit is?
At best, I can currently get it to ask for one number, so its really the dialog interaction that I'm stuck on. Has anyone ever even done anything like this?
Thanks.
Yes to both questions. You could string together a response with 6 different custom slots. "User: My numbers are {num1}, {num2}, {num3}, {num4}, {num5}, {num6} " and make them all required using the skills beta developer. However, it will be a rather bad user experience if the user does not phrase their answer appropriately and Alexa has to ask follow up questions to obtain each number. The last problem you'll run into is that while a custom slot could be defined to contain the numbers 1-50 alexa will generally recognize similar values to those provided in a custom slot, such as numbers from 50-99. It would then be up to you to check that the values you receive are between 1 and 50. If not you'd want to ask the user to provide a different number in the appropriate range.
Conclusion: You'll want to have individual interactions where a user provides a single number at a time.
Alexa:"you will be prompted for 6 numbers between 1 and 50 please state them one at a time. Choose your first number."
User:"50"
Alexa:"Your First number is 50, Next number."...
You can implement this using a single intent. let's name that intent GetNumberIntent. GetNumberIntent will have sample uterances along the line of
{number}
pick {number}
choose {number}
where {number} is a custom slot type or simply AMAZON.NUMBER. It will then be up to you to check that the number is between 1 and 50.
I program in Node.js using the SDK. Your implementation may vary depending upon your language choice.
What I would do is define 6 different state handlers. Each handler should have the GetNumberIntent. When a GetNumberIntent is returned if the slot value is apropriate store the value to the session data and or dynamodb and move forward to the next state. If the slot value is invalid stay for example at state "NumberInputFiveStateHandlers" until a good value is received then change state to the next "NumberInputSixStateHandlers"
var NumberInputFiveStateHandlers = Alexa.CreateStateHandler(states.NUMFIVEMODE, {
'NewSession': function () {
this.emit('NewSession'); // Uses the handler in newSessionHandlers
},
//Primary Intents
'GetNumberIntent': function () {
let message = ` `;
let reprompt = ` `;
let slotValue = this.event.request.intent.slots.number.value;
if(parseInt(slotValue) >= 1 && parseInt(slotValue) <= 50){
this.handler.state = states.NUMSIXMODE;
this.attributes['NUMBERFIVE'] = this.event.request.intent.slots.number.value;
message = ` Your fifth number is `+slotValue+`. please select your sixth value. `;
reprompt = ` please select your sixth value. `;
}else{
message = ` The number `+slotValue)+` is not in the desired range between 1 and 50. please select a valid fifth number. `;
reprompt = ` please select your fifth value. `;
}
this.emit(':ask',message,reprompt);
},
//Help Intents
"InformationIntent": function() {
console.log("INFORMATION");
var message = ` You've been asked to choose a lottery number between 1 and 50. Please say your selection.`;
this.emit(':ask', message, message);
},
"AMAZON.StopIntent": function() {
console.log("STOPINTENT");
this.emit(':tell', "Goodbye!");
},
"AMAZON.CancelIntent": function() {
console.log("CANCELINTENT");
this.emit(':tell', "Goodbye!");
},
'AMAZON.HelpIntent': function() {
var message = `You're playing lottery. you'll be picking six numbers to play the game. For help with your current situation say Information. otherwise you may exit the game by saying quit.`;
this.emit(':ask', message, message);
},
//Unhandled
'Unhandled': function() {
console.log("UNHANDLED");
var reprompt = ' That was not an appropriate response. Please say a number between 1 and 50.';
this.emit(':ask', reprompt, reprompt);
}
});
This is an example of the fifth request. You'll have 6 identical states like this one that string back to back. Eventually you'll end up with 6 session values.
this.attributes['NUMBERONE']
this.attributes['NUMBERTWO']
this.attributes['NUMBERTHREE']
this.attributes['NUMBERFOUR']
this.attributes['NUMBERFIVE']
this.attributes['NUMBERSIX']
You can then use these values for your game.
If you have not used the alexa-sdk before you must remember to register your state handlers and add your modes to the states variable.
alexa.registerHandlers(newSessionHandlers, NumberInputOneStateHandlers, ... NumberInputSixStateHandlers);
var states = {
NUMONEMODE: '_NUMONEMODE',
...
...
NUMSIXMODE: '_NUMSIXMODE',
}
This answer is not intended to cover the basics of coding using Alexas-SDK. There are other resourced for more specific questions on that topic.
Alternatively, because your intent is identical [GetNumberIntent], you may be able to get by with a single StateHandler that pushes new valid numbers onto an array until the array is the desired length. That would simply require more logic inside the Intent Handler and a conditional to break out of the state once the array is of length 6.
Try the code above first because it's easier to see the different states.
I encounter this problem repeatedly, and haven't a clue what is causing it. I get an exception in the DataBind: SelectedValue which is invalid because it does not exist in the list of items.
Here are some important pieces of information:
I reload listOrgs periodically when the underlying data has changed.
The Organization.DTListAll call returns 2 Int, String pairs.
There are no duplicate or null values in the returned data
After the first two lines below, listOrgs.Items.Count is 0, and the Selected Value is 0
The selected value after the DataBind operation executes is the ID value from the first row in the data
This exception happens the very first time this code is executed after a fresh page load
listOrgs.Items.Clear();
listOrgs.SelectedValue = "0";
listOrgs.DataSource = new Organization().DTListAll(SiteID);
listOrgs.DataTextField = "OrganizationName";
listOrgs.DataValueField = "OrganizationID";
listOrgs.DataBind();
Apparently the solution I posted wasn't entirely effective... Eventually in my application I changed to this:
listOrgs.Items.Clear();
listOrgs.SelectedIndex = -1;
listOrgs.SelectedValue = null;
listOrgs.ClearSelection(); // Clears the selection to avoid the exception (only one of these should be enough but in my application I needed all..)
listOrgs.DataSource = new Organization().DTListAll(SiteID);
listOrgs.DataTextField = "OrganizationName";
listOrgs.DataValueField = "OrganizationID";
listOrgs.DataBind();
I kept getting this error.
Weird thing is that before I set the datasource and rebind after deleting an item the selected index = -1.
If I explicitly set the selectedIndex = -1; then it works and doesn't throw an error.
So even though it was already -1 setting it to -1 stops it from erroring.
Weird eh?
Try setting listOrgs.SelectedValue = "0" after you refresh the DataSource
At the moment you are trying to select the first item in an empty list.
Change the first two line with this :
listOrgs.SelectedItem.Selected = false;
listOrgs.Items.Clear();
In case you still have this problem this is how i resolved it:
listOrgs.SelectedIndex = -1; // Clears the SelectedIndex to avoid the exception
listOrgs.DataSource = new Organization().DTListAll(SiteID);
listOrgs.DataTextField = "OrganizationName";
listOrgs.DataValueField = "OrganizationID";
listOrgs.DataBind(); //Unless you have "listOrgs.AppendDataBoundItems = true" you don't need to clear the list
#PMarques answer helped me out and did solve my problem.
However whilst experimenting, it clicked in my head why I was gettign the error in the first place.
I was setting the "Text" attribute thinking that it might create an encompassing label or fieldset + legend, for me (which it doesn't).
The Text property for a list is infact the SelectedValue property for a ListControl.
So my mistake in misinterpreting what the text property did.
Not sure it is your case, but I had the same problem and apparently there was no explanation, then I realized doing a copy and paste on notepad of a field of database that at the beginning of the value there was a NULL.
Curious thing was that a select joining tables was working. I deleted the row and reinserted, after was working fine.
I was getting the same error repeatedly and try ending up by not setting the default selected value to Index -1.
I commented my code ddlDRIBidAmt.SelectedValue = -1
This value was set at the time where my Page Controls were reset to default values.
I know its too late to answer, but what I tried is an dirty solution but it worked.
After databinding, I am insert a item at index 0
ddl.Items.Insert(0, new ListItem("---Select---","-1"));
And on setting,
I am placing try catch, In catch i am setting Value to -1
