How to search with pdf.js?

This is an old thread however I think people should know how the package works now. I have managed to make it work the following way. I was using an iframe to display the pdf.


const iframeDocument = document.getElementById('pdf-js-viewer').contentWindow;
let searchText = "TheTextYouWantoToHighlight";
iframeDocument.PDFViewerApplication.pdfViewer.findController.executeCommand('find', {
    caseSensitive: false, 
    findPrevious: undefined,
    highlightAll: true, 
    phraseSearch: true, 
    query: searchText
})

With the latest version of pdfjs, this works but gives error in console to use dispatch event. This code will remove that error and works as expected.


const iframeDocument = document.getElementById('pdf-js-viewer').contentWindow;
let searchText = "TheTextYouWantoToHighlight";
iframeDocument.PDFViewerApplication.eventBus.dispatch('find', {
    caseSensitive: false,
    findPrevious: undefined,
    highlightAll: true,
    phraseSearch: true,
    query: searchText
});
