Thenks a lot Mario. I modify my macro and now it's ok. I will try again to implement it but the result it's fine for the moment.
In this example in a tiddler I call the macro with a url <<getDataFromUrl "Eureka" "https://en.wikipedia.org/wiki/Eureka_(word)">> and after I will have a new tiddler loaded asynchronously with tiddlername = "Eureka" and the text of tiddler the returned data from service http://heckyesmarkdown.com/go/ Here is the code that I use: /*\ title: $:/paulin/demo/getDataFromUrl.js type: application/javascript module-type: macro <<getDataFromUrl "tiddlername" "url">> Example to get data from wikipedia: <<getDataFromUrl "Eureka" "https://en.wikipedia.org/wiki/Eureka_(word)">> \*/ (function(){ /*jslint node: true, browser: true */ /*global $tw: false */ "use strict"; exports.name = "getDataFromUrl"; exports.params = [ {name: "tiddlername"},{name: "url"}]; /* Run the macro */ exports.run = function(tiddlername,url) { var url = url || "None"; var tiddlername = tiddlername || "None"; //console.log("**** url > "+url); //console.log("**** tiddler > "+tiddlername); //thanks to http://heckyesmarkdown.com/ for the api to get markdown $tw.utils.httpRequest({url: "http://heckyesmarkdown.com/go/?u="+url, callback: function (error,data){ if (error){ console.log("ERROR:"+error); } $tw.wiki.addTiddler({title:tiddlername, text:data, type: "text/x-markdown"}); console.log(data); }}) return "[["+tiddlername+"]]"; }; })(); Il giorno lunedì 8 agosto 2016 11:38:37 UTC+2, PMario ha scritto: > > Hi Paulin, > > Sorry for the late reply. ..
