Hello!

I need to call an external JS script, but I don't want to declare all
of the external script functions and don't know all of them...

Can I do something like
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i
window.ExternalLibName.function()inside my Pascal code?

Thanks in advance, any help is appreciated.

The point of Pascal is to declare first. So you must to declare them.

From what I can see it doesn't.

You can declare only function you need. For example:

Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  
TJSSignaturePad = class external name 'SignaturePad' (TJSObject)    
constructor new (aTarget : TJSElement; const aOptions : TJSObject);  
procedure fromData(Value: JSValue);  end;

Why not use a asm block?
But read "Why are asm blocks bad".

Below is a fully working pas2js example, note Result is case-sensitive
in the asm block!
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i var  val:
jsvalue;function movementQueryWorld: jsvalue;begin  asm     Result =
window.movementQuery(world) // https://github.com/NateTheGreatt/bitECS
/blob/master/docs/INTRO.md#-query  end;end;begin  val:=
movementQueryWorld();  writeln('From Pascal', val);end.

Thank you all!

Solved by creating a wrapper in JS and on Pascal with calls for
external wrapper functions. This way I can change whatever is needed
in the wrapper and keep the calls in Pascal.

Thank you for all the help!
