FormAPI keyup event

ShaileshM

Hi,
I need to do validation based on key up event using form api.
Pls suggest me how can i get it working.
I m using teamsite 6.5

Thanks

There is currently no support for this event. Without a serious JS hack, there is no way to do this.

What are you trying to do with your key up event? Can you present the entire scenario? Perhaps there is something that can be done instead of trying to sense a key up event.

I m trying to put a validation on a text field.I want to restrict the max no of character entered upto 50...user should get the alert message as he/she crosses the limit while entering the data.
i.e. before the item change as well as form save events.
Is there any other way to achieve this w/o using keyup events and setting the maxlength attribute...the alert message is a must requirement.

Thanks

For FormAPI I believe you are limited to onItemChange events - which can do the validation and put up the alert box (and, if you're lucky, re-set the focus back to the offending field) - but it won't tell them they've created a problem on the 51st character - it will only tell them after they have finished composing the entry to the field.

If this is a text field (as opposed to a textarea field) then the maxlength setting will prevent them from being able to enter a 51st character (assuming maxlength=50) - but they won't get an alert. (One might question why you would let them enter in more than N characters in a text field if you are only going to allow N to be accepted).

In this case - you should make use of the description element in the DCT which will provide the per-field pop-up help and try to get all users to go through some kind of training.

ShaileshM

Thanks for the help..i think description element will solve the purpose.
can anyone suggest me how can i set the maxlength attribute dynamically.
i.e. i will read the length of that attribute from the database and set it as maxlength attribute for that element at DCT at the time of form load.

Thanks

Use an inline to load the item. Read the manual to find out how to use them or do a search on the forum if you don't already know.

by dynamically setting the maxlength attribue i mean that at any particular moment i need to set it..by using some method...but there is no such/similar method like IWItem.setMaxLength().
So can you give some idea that by using load item how can i set the value of maxlength attribute.
or is there any other way..?

Thanks

In your DCT under data-capture-requirements call inline command and then in the perl file write watever the thing you want to write.

inline command line can be used for

to populate a field dynamically or
to create a DCT dynamically

If you use the second approach then your problem will resolve.

The inline command is processed prior to form initialization and therefore cannot be used to dynamically alter the form after it has already been rendered - which I believe is what ShaileshM is looking for.

No - there is no supported FormAPI mechanism for adjusting the maxlength of a text field dynamicall.

You could, potentially, do this with "raw" javascript code - but I'm not 100% sure of "how" nor whether it will actually work.

I do have to wonder why you wouldn need to dynamically alter the maxlength of a text field dynamically though - it sounds suspiciously like you're trying to design a one-size-(doesn't)-fits-all DCT.

ShaileshM

ya Mr.Ghoti is exactly correct.. i m looking to alter the maxlength attribute dynamically. Actly as i told earlier my requirement is to match the length of a DCT field with the length of database field.

Thanks for the help...

But if all you're doing is trying to set the max length of the field to a set value from the database, you can do this with an inline. Just have the inline return the proper max length attribute for the item based on this value in the database.

Adam,

Adam,

You seem to be missing my point. I know you can use an inline script to generate part (or even the entire) DCT and that process can be "dynamic" in terms of pre-rendering of the form - but that was *not* what was being asked for.

Your posted code does nothing dynamically - it simply outputs a pre-set DCT via an inline - so I'm not sure it's a particularly good example of what you were trying to suggest in the first place.

I still question the need for the "dynamic" aspect of the maxlength fields in the DCT - however I think Jeff managed to take what I was concerned about with what you were suggesting with what was asked for originally and provided the most likely solution:

But if all you're doing is trying to set the max length of the field to a set value from the database, you can do this with an inline. Just have the inline return the proper max length attribute for the item based on this value in the database.

i.e. either on a field-by-field level, or a whole-cloth level (as per your example) - have the inline script query the DB to find the correct maxlength for the field(s) in question and generate the correct DCT code so that when the form is rendered it will have the correct hard-coded values for maxlength on the field(s) in question.

Adam,

in your example a DCT is being callled by an ipl. But the DCT is still hard coded.What my requirement is to set the maxlength dynamically i.e. on form load.
The main issue is to set the value as maxlength attribute of an item.
i.e. if we have the value..how can we set it on form load...

On Form initialization (when it is starting to render the DCT as a form, but before there are any values retrieved from a DCR) - do you have sufficient information to query your DB to retrieve the maxlength information?

If so - then you can do all that within the inline script while the DCT is being constructed in preperation of being rendered.

If you need to wait until some aspect of the DCR has been read/processed or some other field of information has been filled in - before you can determine what information from the DB you need to query in order to determine what the maxlength for this troublesome field is - then no, inline scripts won't help.

As I stated before, in this situation - you would either have to play around with raw javascript access to the form elements and their attributes ... or ... use a combination of FormAPI and a Callout. Use FormAPI to mark the text field readonly, and use a callout (I believe they'd have to be distinct elements) that will

retrieve the information it needs from the DB, render a text field for the user to fill in, with the appropriate maxlength setting, and then on submit of the callout form, set the value in the DCT form so that it will be saved in the DCR.However - if this is the case, I think there's some very flawed logic in the design of (or perhaps requirements for) the DCT.
