Can't change/jump to page

I’m using this library with React to render the whole pdf document and also have the function to go to particular page. The strange thing is that I can’t jump to page only when I’m rendering my whole document with new pdfjsViewer.PDFViewer , but when I’m using new pdfjsViewer.PDFSinglePageViewer for rendering just one page at the time I can normally jump to page and implement all other functions.

This is some of my code:

import * as pdfWorker from 'pdfjs-dist/build/pdf.worker'
import PdfJsLib from 'pdfjs-dist';
import 'pdfjs-dist/web/pdf_viewer.css';
import * as pdfjsViewer from 'pdfjs-dist/web/pdf_viewer';

...

componentDidMount() {
        let container = this.viewerContainer.current;
        let viewer = this.viewer.current;

        PdfJsLib.GlobalWorkerOptions.workerSrc = pdfWorker;
        PdfJsLib.getDocument(this.props.file).then((pdf) => {

            this.setState({numPages: pdf.numPages});

            this.pdfLinkService = new pdfjsViewer.PDFLinkService();

            this.pdfFindController = new pdfjsViewer.PDFFindController({
                linkService: this.pdfLinkService,
            });

            this.pdfViewer = new pdfjsViewer.PDFViewer({
                 container,
                 viewer,
                 linkService: this.pdfLinkService,
                 findController: this.pdfFindController
            });
            this.pdfLinkService.setViewer(this.pdfViewer);

            this.pdfViewer.setDocument(pdf);
            this.pdfLinkService.setDocument(pdf, null);

            this.pdfViewer.onePageRendered.then(() => {
                 pdf.getOutline().then((outline) => {
                     this.outline = outline || null;

                     if (!outline) {
                        return;
                     }
                     this.setState({bookmarkItems: outline});
            });
       });
   });
}



...

onNextPageClick = () => {
    if(this.state.numPages > this.state.pageNumber) {
        this.setState({pageNumber: this.state.pageNumber + 1});
        this.setState({pageNumberInput: this.state.pageNumber + 1});

        this.pdfViewer.currentPageNumber++;
    }
}
onPreviousPageClick = () => {
    if(this.state.pageNumber > 1) {
        this.setState({pageNumber: this.state.pageNumber - 1});
        this.setState({pageNumberInput: this.state.pageNumber - 1});

        this.pdfViewer.currentPageNumber--;
    }
}

...

render() {
    return(

        ...

        <div className="splitToolbarButton hiddenSmallView">
            <button className="toolbarButton pageUp" title="Previous Page" id="previous" tabIndex="13" data-l10n-id="previous" onClick={this.onPreviousPageClick}>
            <span data-l10n-id="previous_label">Previous</span>
            </button>
         <div className="splitToolbarButtonSeparator" />
            <button className="toolbarButton pageDown" title="Next Page" id="next" tabIndex="14" data-l10n-id="next" onClick={this.onNextPageClick}>
             <span data-l10n-id="next_label">Next</span>
            </button>
        </div>

         ...

        <div id="viewerContainer" ref={this.viewerContainer}>
            <div id="viewer" ref={this.viewer} className="pdfViewer" />
        </div>
    )
}

Is there anything that I’m doing wrong here or am I missing something?

Configuration:

• Web browser and its version: Chrome 71.0.3578.98
• Operating system and its version: Windows 10
• PDF.js version: 2.0.489

I found where my problem was. I wasn’t aware that div element with id viewerContainer has to have position: absolute so that scrollIntoView actually do something. The same goes for the div element mainContainer. Of course it make sense now but I was looking at the wrong places all the time thinking it has to do something with react or services like PDFLinkService. @timvandermeij Thank you for the help.

From the description it’s not clear what you mean by “jumping to a page”. If you mean changing the page, you can use the PDFViewer.currentPageNumber setter (https://github.com/mozilla/pdf.js/blob/master/web/base_viewer.js#L207). Moreover, as outlined in https://github.com/mozilla/pdf.js/blob/master/.github/CONTRIBUTING.md, just code snippets won’t help to debug the issue:

If this does not help, please prepare a short well-documented example that demonstrates the problem and make it accessible online on your website, JS Bin, GitHub, etc. before opening a new issue or contacting us on the IRC channel – keep in mind that just code snippets won’t help us troubleshoot the problem.
