Add a custom "Save" button
This sample shows how to add a custom "Save" button to the main viewer toolbar that saves the edited PDF on the server using SupportApi.
app.js
index.html
styles.css
window.onload = function() {
//DsPdfViewer.LicenseKey = "***key***";
let viewer, React;
// Prepare viewer options:
const options = {
workerSrc: "/document-solutions/javascript-pdf-viewer/demos/product-bundles/build/dspdfviewer.worker.js",
supportApi: getSupportApiSettings()
};
// Arbitrary data associated with the viewer.
// This data is sent to the server when the document is saved:
options.userData = { sampleName: 'SaveChangesSample', docName: new Date().getTime() + '.pdf' };
// Create viewer instance:
viewer = new DsPdfViewer("#viewer", options);
// Add annotation editor:
viewer.addAnnotationEditorPanel();
// Create custom 'Save changes' button
React = viewer.getType('React');
