Runs/Executes a string as JavaScript code.⤶
<note>This function does **NOT** evaluate expression (i.e. allow you to pass variables from JavaScript (JS) to Lua context).&lt;br&gt;Because a return value is nil/no value (a.k.a. void).&lt;br&gt;If you wish to pass/return values from JS to Lua, you may want to use <page>DHTML:AddFunction</page> function to accomplish that job.</note>⤶

dframe:SetTitle( "Garry's Mod Wiki" )⤶

⤶
-- Create a new DHTML panel as a child of dframe, and dock-fill it.⤶
local dhtml = vgui.Create( 'DHTML', dframe )⤶
dhtml:Dock( FILL )⤶
-- Navigate to Garry's Mod wikipedia website.⤶
dhtml:OpenURL( 'https://wiki.garrysmod.com/index.php' )⤶
-- Run JavaScript code.⤶
dhtml:QueueJavascript( <page>document.body.innerHTML = 'HTML changed from Lua using JavaScript!';</page> )⤶
⤶
-- This does not throw an error/exception, but instead returns nil/no value.⤶

local number = dhtml:QueueJavascript( '22;' )⤶
print( number )⤶
