Inject Jquery issue

Closed

assured_kumquat opened this issue

Hi,

It seems not possible to inject jquery as specified in the documentation.

What is the proper way do do that ?

async function pageFunction(context) {
    const { page, request, Apify } = context;

    await Apify.utils.puppeteer.injectJQuery(page);

//  "Apify.utils" is undefined
    
    return {
        url: request.url,
    };
}

Thanks

The method is now directly available in the crawling context and you no longer need to provide the page option as it gets used automatically:

https://crawlee.dev/api/puppeteer-crawler/interface/PuppeteerCrawlingContext#injectJQuery

async function pageFunction(context) {
    const { request, injectJQuery } = context;
    await injectJQuery();

    return {
        url: request.url,
    };
}

Where did you find the example? Current docs are correct, they only contain the contextual helper, so closing as answered. Be sure to read the latest version of the docs, sounds like you are viewing the old one for v2.

FYI the academy docs still have the old v2 example, i ran into this issue today: https://docs.apify.com/academy/apify-scrapers/puppeteer-scraper
