why my jsPDF does not work?

[msmichael]

Hi experts,

I'm new to QV extensions and JavaScript. I want to create a document extension that uses jsPDF to export some custom charts to pdf. However I'm not able to make it work. I'm using QlikView 11 version.

This is what I did,

create a folder in "C:\Users\usename\AppData\Local\QlikTech\QlikView\Extensions\Document\rrprint"

create a Definition.xml file with contents as below:

<?xml version="1.0" encoding="utf-8"?>

<ExtensionObject Label="rrprint" Path="rrprint" Description="allow share window to export" Type="document">

</ExtensionObject>

create a Script.js file with contents as below:

function rrprint_Init() {

Qva.AddDocumentExtension("rrprint",

function () {

var _this = this;

_this.ExtSettings = {};

            _this.ExtSettings.ExtensionName = 'rrprint';

            _this.ExtSettings.LoadUrl = Qva.Remote + (Qva.Remote.indexOf('?') >= 0 ? '&' : '?') + 'public=only' + '&name=';

// Define one or more javascript files to be used within the extension

var jsFiles = [];

jsFiles.push('Extensions/' + _this.ExtSettings.ExtensionName + '/lib/js/jspdf.debug.js');

alert(jsFiles[0]);

Qv.LoadExtensionScripts(jsFiles, function () {

                alert("loaded");

                var d = new jsPDF();

            });

        }

    )

};

rrprint_Init();

Create sub-folder inside \rrprint folder as .\lib\js\, and put the jspdf.debug.js there.

However, when I run it, I always got error: "jsPDF" is undefined. Is there anything I did incorrectly?

Thank you!

Another question is, how to import a web hosted library? 

for example, for jsPDF, the lib url is here: "https://unpkg.com/jspdf@latest/dist/jspdf.min.js",

how should I write it in  LoadExtensionScripts function?

I tried below, but does not work,

var jsFiles = [];

jsFiles.push('https://unpkg.com/jspdf@latest/dist/jspdf.min.js');

Qv.LoadExtensionScripts(jsFiles, function () {

                alert("loaded");

                var d = new jsPDF();

                d.text(20, 20, 'Hello landscape world!');

                d.save('Test.pdf');

});

receive this error:
