Hi,

it'd be nice to send from my pas2js file something outside. Let's say
after pushing WButton it sends to fphttpserver some parameters which
then I'm able to catch with aReqest.QueryFields.Values[..] and work
with. A little blindly I try 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
WButton.OnClick()var  paramsOut3 : TJSURLSearchParams;  url : TJSURL; 
P : TJSObject; begin  {http://192.168.1.4:8080/?txt=22}              
   //this is my href   p:=New(['url',window.locationString]); 
url:=TJSURL(p);                                             // now it
should be already url.href assigned  url.href:=string(p['url']);     
                          //but doesn't and I have to make it by hand,
  showmessage(url.href);                                  //seems to
be ok...  paramsOut3:=url.SearchParams;                    //so now
time to separate searchParams  paramsOut3.append('txt2','12s');      
            //error: cannot append to 'undefined', why is
undefined?end;
So probably I try make it wrong. Someone knows how to modify url by
appendin new params from pas2js?

Regards,

Also this doesn't seem to be ok
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  
url:=TJSURL(window.location);  paramsOut3:=url.SearchParams; 
paramsOut3.set_('txt','34');    //error undefined

That works.
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  
 url:=TJSURL.new(window.locationString); 
paramsOut3:=TJSURLSearchParams.new;  paramsOut3:=url.SearchParams; 
paramsOut3.set_('txt','12s');  console.log(url.href); 
window.location.href:=url.href; where
  paramsOut3 : TJSURLSearchParams;
  url : TJSURL;
