Generating PDF with jsPDF

Question

I'm trying to print a table from my webpage as pdf with jsPDF. I create the table in a new window, and what I was doing before find jsPDF was printing the whole new page with the mapped table, but now I need to download the pdf without show the printing wizard, so I tried the jsPDF scripts for my purpose, but I'm not being able to print the correct format of my table. I have to say I'm using another js called JsBarcode because I need to generate a barcode in my table and print it in the PDF, and for now I'm not being able to print it correctly.

Here is my JavaScript code:

JsBarcode(".barcode").init(); 
var doc = new jsPDF(); 
var specialElementHandlers = {
    "#bypassme": function (element, renderer) {
        return true
    }
}; 
var margins = {
    top: 80,
    bottom: 60,
    left: 40,
    width: 522
}; 
var source = $("#content")[0];
doc.fromHTML(
    source.innerHTML,
    margins.left, 
    margins.top, 
    {
        "width": margins.width,
        "elementHandlers": specialElementHandlers
    }, 
    function (dispose) { 
        doc.save("Test.pdf"); 
    }, 
    margins
); 

Here is the HTML:

<div id="content">
<table border="2px" class="table" style="border: 2px dashed #000; border-collapse: collapse;" >
    <tr>
        <td style="border: 0px;">
            <table class="table" style="font-size:13px;">
                <tr style="background-color:#bdbdbd;">
                    <td>VALUE_0</td>
                </tr>
                <tr>
                    <td style="border: 0px;">VALUE_0.1</td>
                </tr>
                <tr>
                    <td style="border: 0px;">VALUE_0.2</td>
                </tr>
                <tr>
                    <td style="border: 0px;">VALUE_0.3</td>
                </tr>
                <tr>
                    <td style="border: 0px;">VALUE_0.4</td>
                </tr>
            </table>
        </td>
        <td style="border: 0px;">
            <table class="table" border="2px" solid>
                <tr style="background-color:#bdbdbd;">
                    <td><b>VALUE_1</b></td>
                </tr>
                <tr>
                    <td style="border: 0px;"><b>VALUE_1.1</b></td>
                </tr>
                <tr>
                    <td style="border: 0px;"><b>VALUE_1.2</b></td>
                </tr>
                <tr>
                    <td style="border: 0px;"><b>VALUE_1.3</b></td>
                </tr>
                <tr>
                    <td style="border: 0px;"><b>VALUE_1.4</b></td>
                </tr>
            </table>
        </td>
    </tr>
    <tr>
        <td style="border: 0px;">
            <p><b>VALUE_2</b></p>
            <p><b>VALUE_3</b></p>
            <p><b>VALUE_4</b></p>
            <p><b>VALUE_5</b></p>
        </td>
        <td style="text-align:center; border:0px;">
            <svg class="barcode" jsbarcode-format="code128" jsbarcode-value="VALUE_6" jsbarcode-textmargin="0" jsbarcode-margin="0" jsbarcode-height="50" jsbarcode-fontSize="18" jsbarcode-fontoptions="italic"></svg>
        </td>
    </tr>
</table>
</div>

I've added jquery, jsbarcode and jspdf libraries. This is that I get when I print the whole page (calling the window.print() event with the console and saving it as pdf)

And this is what I have when I send to console the script doc.save("test.pdf");

NOTE: I script the doc.save("test.pdf") on the console because I'm being unable to execute the "function(dispose)" code

Thanks for the help!

UPDATE: I'm trying the same code without the part of function(dispose), just like this

document.onload = setTimeout(function () {
    JsBarcode(".barcode").init(); 
    var doc = new jsPDF(); 
    var specialElementHandlers = {
        "#bypassme": function (element, renderer) {
            return true
        }
    }; 
    var margins = {
        top: 80,
        bottom: 60,
        left: 40,
        width: 522
    }; 
    var source = $("#content")[0];
    doc.fromHTML(
        source.innerHTML,
        margins.left, 
        margins.top, 
        {
            "width": margins.width,
            "elementHandlers": specialElementHandlers
        }
    );

    doc.save("Test.pdf"); 
}, 500);

And now I'm getting the pdf without code anything on the console, but the table is not mapped and the barcode is not showing...

Since you already have jQuery, try using document.ready.

JsBarcode(".barcode").init(); 

$( document ).ready(function() {
var doc = new jsPDF(); 
var specialElementHandlers = {
    "#bypassme": function (element, renderer) {
        return true
    }
}; 
var margins = {
    top: 80,
    bottom: 60,
    left: 40,
    width: 522
}; 
var source = $("#content")[0];
doc.fromHTML(
    source.innerHTML,
    margins.left, 
    margins.top, 
    {
        "width": margins.width,
        "elementHandlers": specialElementHandlers
    }, 
    function (dispose) { 
        doc.save("Test.pdf"); 
    }, 
    margins
); 
});
