I want to convert some of my divs into PDF and I've tried jsPDF library but with no success. It seems I can't understand what I need to import to make the library work. I've been through the examples and I still can't figure it out. I've tried the following:
<script type="text/javascript" src="js/jspdf.min.js"></script>
After jQuery and:
$("#html2pdf").on('click', function(){
var doc = new jsPDF();
doc.fromHTML($('body').get(0), 15, 15, {
'width': 170
});
console.log(doc);
});
for testing purposes but I receive:
"Cannot read property '#smdadminbar' of undefined"
where #smdadminbar
is the first div from the body.
fromHTML
or why it isn't documented in the jsPDF docs: "We are closing this issue, because we will not support any longer fromHTML and addHTML." (from issue#516)
you can use pdf from html as follows,
Step 1: Add the following script to the header
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>
Step 2: Add HTML script to execute jsPDF code
Customize this to pass the identifier or just change #content to be the identifier you need.
<script>
function demoFromHTML() {
var pdf = new jsPDF('p', 'pt', 'letter');
// source can be HTML-formatted string, or a reference
// to an actual DOM element from which the text will be scraped.
source = $('#content')[0];
// we support special element handlers. Register them with jQuery-style
// ID selector for either ID or node name. ("#iAmID", "div", "span" etc.)
// There is no support for any other type of selectors
// (class, of compound) at this time.
specialElementHandlers = {
// element with id of "bypass" - jQuery style selector
'#bypassme': function (element, renderer) {
// true = "handled elsewhere, bypass text extraction"
return true
}
};
margins = {
top: 80,
bottom: 60,
left: 40,
width: 522
};
// all coords and widths are in jsPDF instance's declared units
// 'inches' in this case
pdf.fromHTML(
source, // HTML string or DOM elem ref.
margins.left, // x coord
margins.top, { // y coord
'width': margins.width, // max width of content on PDF
'elementHandlers': specialElementHandlers
},
function (dispose) {
// dispose: object with X, Y of the last line add to the PDF
// this allow the insertion of new lines after html
pdf.save('Test.pdf');
}, margins
);
}
</script>
Step 3: Add your body content
<a href="javascript:demoFromHTML()" class="button">Run Code</a>
<div id="content">
<h1>
We support special element handlers. Register them with jQuery-style.
</h1>
</div>

You only need this link jspdf.min.js
It has everything in it.
<script src="https://cdnjs.cloudflare.com/ajax/libs/jspdf/1.3.2/jspdf.min.js"></script>
Error in function FileSaver@http://mrrio.github.io/jsPDF/dist/jspdf.debug.js:5875:18: get_URL(...).createObjectURL is not a function
, same thing if I use the bower version. Any clue?

According to the latest version (1.5.3) there is no fromHTML()
method anymore. Instead you should utilize jsPDF HTML plugin, see: https://rawgit.com/MrRio/jsPDF/master/docs/module-html.html#~html
You also need to add html2canvas library in order for it to work properly: https://github.com/niklasvh/html2canvas
JS (from API docs):
var doc = new jsPDF();
doc.html(document.body, {
callback: function (doc) {
doc.save();
}
});
You can provide HTML string instead of reference to the DOM element as well.
This is finally what did it for me (and triggers a disposition):
function onClick() { var pdf = new jsPDF('p', 'pt', 'letter'); pdf.canvas.height = 72 * 11; pdf.canvas.width = 72 * 8.5; pdf.fromHTML(document.body); pdf.save('test.pdf'); }; var element = document.getElementById("clickbind"); element.addEventListener("click", onClick);
And for those of the KnockoutJS inclination, a little binding:
ko.bindingHandlers.generatePDF = {
init: function(element) {
function onClick() {
var pdf = new jsPDF('p', 'pt', 'letter');
pdf.canvas.height = 72 * 11;
pdf.canvas.width = 72 * 8.5;
pdf.fromHTML(document.body);
pdf.save('test.pdf');
};
element.addEventListener("click", onClick);
}
};
pdf.save("myfile.pdf", function(){ alert("pdf generation/save finished!"); });
how about in vuejs how is it applicable?
function onClick() { var pdf = new jsPDF('p', 'pt', 'letter'); pdf.canvas.height = 72 * 11; pdf.canvas.width = 72 * 8.5; pdf.fromHTML(document.body); pdf.save('test.pdf'); }; var element = document.getElementById("clickbind"); element.addEventListener("click", onClick);
Shouldn't you also be using the jspdf.plugin.from_html.js library? Besides the main library (jspdf.js), you must use other libraries for "special operations" (like jspdf.plugin.addimage.js for using images). Check https://github.com/MrRio/jsPDF.
first, you have to create a handler.
var specialElementHandlers = {
'#editor': function(element, renderer){
return true;
}
};
then write this code in click event:
doc.fromHTML($('body').get(0), 15, 15, {
'width': 170,
'elementHandlers': specialElementHandlers
});
var pdfOutput = doc.output();
console.log(">>>"+pdfOutput );
assuming you've already declared doc variable. And Then you have save this pdf file using File-Plugin.
