Update gon variables on an ajax request about gon

[ULKARAMAKRISHNAN]

Hi,

I do gon.variable_name = value in my controller and in my js file I use gon.variable_name. It works fine for full page reloads but for ajax request it doesnt gets updated.

Say for example on page reload, in my controller I do gon.variable_name = value1 and in my js gon.variable_name gives me value1. After a ajax request in my controller I do gon.variable_name = value2 and in my js I strill see gon.variable_name as value1 only.

Is there any way I could update gon.variable_name in a ajax request?

Thanks

I think I am having a similar issue.

I do a file upload using ajax then call a controller. I'm updating the gon.variable in the controller then trying to display it on the success action. It doesn't update.

Is this a bug or is there a better way to be doing this?

@benniemietz there is a functionality in version 4.0.0 which allow you to get any variable from controller by ajax request, please look this wiki page - https://github.com/gazay/gon/wiki/Usage-gon-watch

If it doesn't help you - can you describe problem with full example? I mean step-by-step.

@perkins2099 maybe you should try to use global gon variables, or functionality gon.watch? Do you call controller through ajax? What kind of variable you try to renew?

I am also unable to get gon.watch to work. Fetching a js script via an ajax request, I am setting my gon variables through gon.watch.var_name = ... in the controller and the gon vars are successfully updated. However, this change is not seen by the javascript. Should I be calling gon.watch('var_name') to update the var in js as well? Using the js method gon.watch and setting an interval has not worked for me either.

[gazay]

Gon.watch functionality works right now only like getter in JS, it don't change original object window.gon.watchedVariables.

So you can get your current value like this:

var newVal = gon.watch('var_name');
if (newVal == gon.watchedVariables['var_name']) {
...

Thanks, I wasn't clear on that :).

Hi, a few of questions.

• Can I use the gon.variables in another action of controller?
• In the usage for gon.watch says, we can change from js.coffee or whatever, but would be possible change in several controller actions?
• This gon.watch it's only for variables?, not for rabl files?
  Thanks.
