how to update value= attribute

[Franklin Brauning]

I'm making a widget

<progress class="progress" value="15" max="100">15%</progress>

and I want to update that value= atribute from server

The text is wf:replace(Id, "90%"), but how about with the value= atribute?

[Franklin Brauning]

wf:set(TargetID, Value)  will do it, right?

Replace replaces a whole element i.e. it would replace the whole progress bar. BUT nitrogen uses classes currently to replace things.That looks like html rather than erlang. so you have to set name i.e. 
<progress class="wfid_progress" value="15" max="100">15%</progress>

then use wf:set("progress", "90").

to set the value/textbox. 

I haven't tested what I said above but believe that would most likely either set value not body. If you share the css/js for the progress bar may be able to suggest something being able to test.

Hi Franklin,

It depends on what attribute you're trying to set.  Using wf:set on a form element will change its value. Using it on an image will change its src attribute. 

You'll need to update the value with jquery, which can be simplified a bit with the objs(ID) javascript function:

wf:wire("objs('elementid').prop('value', '15)")

That said, modifying the #set{} action to support an attribute attribute (heh) might be a good idea:

wf:wire(Id, #set{attribute="some value"}).

And making a separate wf shortcut call for it like

wf:attribute(Id, "Some value")

Might not be a bad idea.

wf:set would work for setting the value attribute on the progress element because the progress element has a value attribute.

If that's all you want to set, then yes, that'll work.
