How to get URL parameters from the address bar (SOLVED)

buddhika · August 10, 2018, 10:22am

Is there a method to retrieve parameters in a URL, for an example, get the “user” param from the a URL like this.

http://localhost:2453/html5/index.html/?user=asdfresdfgh

I tried to follow the steps given here but it seems difficult to understand. Some clear help on this regard is really valuable at the moment.

I would suggest that you get the URL like this:

local url = html5.run("location.href")

@britzl hi sir ! how way to parse parameter of url ?

There is the example of parsing URL params:

github.com

Insality/druid/blob/master/example/example.gui_script#L228

    
      
          	self.lobby_grid:add(get_button(self, "Inner templates", "system_inner_templates", "/system/inner_templates/inner_templates.gui_script"))
          	self.lobby_grid:add(get_button(self, "Late init check", "system_late_init_check", "/system/late_init_check/late_init_check.gui_script"))
          end
          
          

          
local function check_url(self)
          	if not html5 then
          		return
          	end
          
          
	local example_arg = html5.run("new URLSearchParams(window.location.search).get('example')")
          	if example_arg and self.scene_names[example_arg] then
          		print("Start example: ", example_arg)
          		show_scene(self, example_arg, self.scene_names[example_arg] or "unknown")
          		return true
          	end
          end
          
          

          
local function check_cache(self)
          	local scroll_position = self.cache.scroll_position

Also you can manipulate current user URL args with this:

github.com

Insality/druid/blob/master/example/example.gui_script#L28

    
      
          
          

          
local function save_cache(self)
          	sys.save(cache_path, self.cache)
          end
          
          

          
-- Change current browser URL to share the examples
          ---@param self userdata
          ---@param scene_name string
          local function set_scene_url(self, scene_name)
          	if not html5 then
          		return
          	end
          
          
	local command
          	if scene_name then
          		command = string.format('window.history.replaceState(null, null, "?example=%s")', scene_name)
          	else
          		command = 'window.history.replaceState(null, null, "index.html")'
          	end
