function changeSave(frmInput)

{

alert("Changed");

}

When using time,date,select  on change isnt called, Its strange because if you type stuff in its called but when blakcberry native date,time or option list pops up and you it pritns it to the form but doesnt call on save...

Work arounds or solutions anyone?

Thanks for support

Is that on the PlayBook or on phones?

I had that problem on the playbook with a date field, managed to workaround it using onBlur instead of onChange

[liammccann]

Its smartphone, does on blur has the same effect? e.g.

I only want to call my function if the data has been changed so i can edit my JSON...

[nunodonato]

Didn't try it on the phone, sorry.

Although if it does work, it will call the function even if the data doesn't change. If the code is very performance-intensive, you can add your own manual check before running it.

If its any help to any reading this,

Ive done the following

On focus in save form value to temp varible
On focus out compare new value if temp
If its different then save new variable to JSON
If not then nothing

Basicly my own onchange function using the focus items...

Also the official bug tracker is here: https://github.com/blackberry/WebWorks/issues/122

If you are just saving a variable, does it hurt to save it again even if it didn't change?

Not sure which of the ways runs more code )

[liammccann]

I agree to disagree with you on this one,

Because i am building my JSON dynamicallyi only include form fields that have a value, so saving it if it doesn't change would result in something like
var json {feild1: ""}

If you follow what im saying? What your saying would be good if i was building it dynamically.

[nunodonato]

So what if it has a value and the user changes it by deleting it?

won't it save the "" anyway?

I guess that requires an extra check then...

[liammccann]

Thanks for pointing that out exactly, Very good point will just require a small if statement... Have you done any development on smartphone or anything with a trackpad?
