How to call external JS script?

[zendrael]

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][+][-]

1. 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.

Does pas2js support idispatch ? :-)

From what I can see it doesn't.

You can declare only function you need. For example:

Code: Pascal  [Select][+][-]

1.   TJSSignaturePad = class external name 'SignaturePad' (TJSObject)
2.  
3.     constructor new (aTarget : TJSElement; const aOptions : TJSObject);
4.     procedure fromData(Value: JSValue);
5.   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][+][-]

1. var
2.   val: jsvalue;
3. function movementQueryWorld: jsvalue;
4. begin
5.   asm
6.      Result = window.movementQuery(world) // https://github.com/NateTheGreatt/bitECS/blob/master/docs/INTRO.md#-query
7.   end;
8. end;
9. begin
10.   val:= movementQueryWorld();
11.   writeln('From Pascal', val);
12. end.
13.

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!
