Why data() not attr()

[ivanromakh]

I have a little problem here
https://github.com/wikimedia/jquery.i18n/blob/master/src/jquery.i18n.js#L230

For case of using data-bind="attr: {data-i18n: somevar}"

1. attr updated
2. data not updated

And in the end if I change somevar translation will not changed in my page.
Maybe this is problem of data-bind. I don`t know.
I added class and update data before each translation with next script:

for (let i =0; i < elements.length; i++) {
$(element).data('i18n', $(element).attr('data-i18n'));
}

$('[data-i18n]').i18n();

I think you should add check for attributes too:)
Thanks:)

I have the same problem. How did you solve it?

[aromakh]

@benno-meyer Set attr and then data. Or set data and then attr, don`t remember. So need two operations instead of one.

Ah, I see.
You have to first change the variable with $(element).attr('data-i18n', new_var);
and then refresh the data storage with the new variable $(element).data('i18n', $(element).attr('data-i18n'));

Thank you so much for your help!
