代码:
import React,{ useRef,useEffect } from "react";
import WebViewer from "@pdftron/webviewer";
import "./styles.css";
const App = () => {
const viewer = useRef(null);
// if using a class,equivalent of componentDidMount
useEffect(() => {
WebViewer(
{
path: "lib",initialDoc:
"https://pdftron.s3.amazonaws.com/downloads/pl/webviewer-demo.pdf"
},viewer.current
).then((instance) => {
/*const { docViewer,Annotations } = instance;
const annotManager = docViewer.getAnnotationManager();
docViewer.on("documentLoaded",() => {
const rectangleAnnot = new Annotations.RectangleAnnotation();
rectangleAnnot.PageNumber = 1;
// values are in page coordinates with (0,0) in the top left
rectangleAnnot.X = 100;
rectangleAnnot.Y = 150;
rectangleAnnot.Width = 200;
rectangleAnnot.Height = 50;
rectangleAnnot.Author = annotManager.getCurrentUser();
annotManager.addAnnotation(rectangleAnnot);
// need to draw the annotation otherwise it won't show up until the page is refreshed
annotManager.redrawAnnotation(rectangleAnnot);
});*/
});
},[]);
return (
<div className="App">
<div className="header">React sample</div>
<div className="webviewer" ref={viewer}></div>
</div>
);
};
export default App;
