I am beginner in react-redux.
I trying create a function like exporting a html text to pdf with Javascript and it works with html, but when I apply it to react component, it doesn't work.
This is my code:
import React from 'react';
class App extends React.Component {
constructor(props){
super(props);
this.pdfToHTML=this.pdfToHTML.bind(this);
}
pdfToHTML(){
var pdf = new jsPDF('p', 'pt', 'letter');
var source = $('#HTMLtoPDF')[0];
var specialElementHandlers = {
'#bypassme': function(element, renderer) {
return true
}
};
var margins = {
top: 50,
left: 60,
width: 545
};
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('html2pdf.pdf');
}
)
}
render() {
return (
<div>
<div classID="HTMLtoPDF">
<center>
<h2>HTML to PDF</h2>
<p>Lorem ipsum dolor sit amet, consectetur adipisicing </p>
</center>
</div>
<button onClick={this.pdfToHTML}>Download PDF</button>
</div>
);
}
}
export default App;
Javascript with HTML: https://www.youtube.com/watch?v=HVuHr-Q7HEs
React don't have "classID" property in html tags, it's passed to div as props, which will never be resolved. className was only implemented because it's reserved word in JS, perhabs you need to replace your "classID" by only "id" property and it will work
P.s. JQuery is bad practice when all what you need is DOM manipulation. javascript have document.getElementById() and dependency is not needed
P.p.s. small tip for you is "pdfToHTML(){}" can be replaced to lambda as "pdfToHTML = () => {}", and your function will have "this" from class instance, binding will be removed and constructor will become useless.
This is my way
- You can use that package in pure javascript file or server
side(Backend)
- When you use it with the ReactJS(Frontend), it doesn't work.
- So I didn't use that.
- With html2canvas and jsPDF, I could build pdf.
- First build component, then save(download) it.
