Views - Reload, Refresh, Re-render | How to?

[signalpoint]

Today I ran into the need (yet again) to refresh a View after a custom form is submitted, (i.e. the view was already on the page and the form is building custom exposed filters to be appended to the path of the View that I want to refresh).

Here's a handy function that removes the View from DrupalGap, so it can be reloaded/refreshed/re-rendered (place this in a custom DG7 module):

function dgRemoveView(viewId) {

  // Remove the existing view from the DOM.
  $('#' + viewId).remove();

  // Remove the view from DrupalGap's internal tracker.
  var views = drupalgap.views;
  var index = views.ids.indexOf(viewId);
  if (index != -1) { views.ids.splice(index, 1); }

  // Remove the pageshow event so it can fire again.
  var events = drupalgap.page.jqm_events;
  index = events.indexOf("pageshow-_theme_view-" + viewId);
  if (index != -1) { events.splice(index, 1); }

}

Then for example, you can remove the view then re-append it to the content region:

// Remove the view from the DOM.
dgRemoveView('my-view-id');

// Get the new html ready.
var content = {};
content.my_view = { /*... A Views Render Array using the same id "my-view-id" ... */ };
var html = drupalgap_render(content);

// Append the html to the content region.
var selector = '#' + drupalgap_get_page_id() + ' .region_content';
$(selector).append(html).trigger('create');

A little hacky, but it gets the job done! I'll plan to move dgRemoveView() into DG7 core eventually, give it a new name, and an appropriate home in the docs.

Would this be at all relevant to the issue I encountered with dg8 views in a form not getting to formState?

Negative ghost rider, dg7 only.

Cool, it actually has not been that bad to detect the various selections thus far manually. Just thought I'd check.
