Open a HTML file in JavaScript

The task of reading HTML documents is the task of reading hierarchical data structures within the DOM model. This implies knowing the format of each individual HTML data element, including all of its possible child elements and attributes.

Our JavaScript library is a cloud-based solution that will allow you to open HTML files for reading and writing easily. This distributed approach gives you flexibility in software development using JavaScript language, as all resource-intensive HTML document processing will take place on Aspose servers. All you need is to get private keys to access Cloud API in JavaScript code.

Programmatically read HTML documents in JavaScript

You can iterate over all elements of a HTML document or you can search for specific elements in a DOM tree. We provide a wide range of JavaScript functions both for working with the structure of the HTML file and with the data contained in the document nodes.

The following code example will help you quickly figure out how to load a HTML file using JavaScript and perform some actions on it.

Upload a document you want to access
Run code
import * as fs from "fs";

const wordsApi = new WordsApi("####-####-####-####-####", "##################");
const fileName = "Input.html";

const requestFileContent = fs.createReadStream(fs.readFileSync(
   fileName, 'utf8'));
const uploadDocumentRequest = new model.UploadFileRequest({
    fileContent: requestFileContent,
    path: fileName
});

wordsApi.uploadFile(uploadDocumentRequest)
.then((uploadDocumentRequestResult) => {
    console.log("Result of UploadDocumentRequest: ", uploadDocumentRequestResult);
    const requestParagraph = new model.ParagraphInsert({
        text: "Reading and writing to the file in the cloud occurs automatically."
    })
    const insertParagraphRequest = new model.InsertParagraphRequest({
        name: fileName,
        paragraph: requestParagraph
    });

    wordsApi.insertParagraph(insertParagraphRequest)
    .then((insertParagraphRequestResult) => {
        console.log("Result of InsertParagraphRequest: ", insertParagraphRequestResult);
        const downloadDocumentRequest = new model.DownloadFileRequest({
            path: fileName
        });

        wordsApi.downloadFile(downloadDocumentRequest)
        .then((downloadDocumentRequestResult) => {
            console.log("Result of DownloadDocumentRequest: ", downloadDocumentRequestResult);
        });
    });
});
