Global variable setValue - how to?

[Akayy]

I have a global variable called “name”.

When defining a button click action,

How can I setValue the global variable directly? Basically, I was expecting the global variable to be listed on the left side of the available list of actions (for eg like a normal variable/array component)?

Am I missing some theory (or) is this still not available as a capability?

In fact, I can see the global variable listed in the “data binding” dialog, and able to use it (for eg, assign it to a normal variable).

Hey @Fabriceh $ @Akayy,

I suggest you to check this doc, because it’s showing how variables works and how you can set the value of a variable : https://docs.wappler.io/t/passing-values-between-your-pages/5588
I think this doc is also a good ressource for you if you want to use “SetValue” from your server action : https://docs.wappler.io/t/using-set-value-in-server-connect/11647

Hope this helps

Thanks, variable in wappler is not clear… The question above is about global variable in the app object, not server connect. … Maybe a complete real documentation about each button and possibility of the software is to start …

Really, reading a lot of comment here… it seems that a lot of people stop using wappler because the poor documentation… We can feel its powerful, but still not clear enough … spend lot of time to guess how its working, and searching the forum is … painfull

@Fabriceh
In my first link you can see how to set a value for a variable (global variable or not): https://community.wappler.io/uploads/default/optimized/2X/a/ad2874f17c2522f68473774db3e9cfc995910982_2_690x396.jpeg

While there are some informations missing, I personally love Wappler’s documentation, it’s very rich and that’s part of the reason why I like Wappler.

I haven’t seen anybody leaving Wappler for this reason (yet), but I do see a lot of people coming to Wappler because there is a good support for them or the community, the documentation is not that bad at all, and the software itself is awesome.

Set value - Name and Global Name values discussion

Since day one of using Wappler I confess to being a little unsure of how the server connect Set value component works in relation to names and global names and could not find clarification within forum docs so today I have investigated and these are my conclusions. Names are of course mandatory, global names are optional parameters So here is my take on this and my questions about them We start with [image] At this point I have always assumed that the difference between the Name and the Glo…

Old thread but I wanted to follow up as I was also recently confused by this. I found that you can directly set the value of a global variable like so:

dmx.app.set('name', 'value')

And you can place that in the static events of a button or whatever else. Not sure why I can’t see this as an option on the available list of actions as pointed out by the original post. I have to agree with @Fabriceh that the documentation was lacking in this topic - if it weren’t for help from some colleagues I would never have found this out and any documentation or forum post regarding this were more related to working with Javascript functions.
