How to Prevent PhantomJS's `onLoadFinished` Callback from Firing Prematurely During Asynchronous Page Loading?

PhantomJS Callback Firing Prematurely During Async Page Loading

PhantomJS users encountering premature firing of the onLoadFinished callback, hindering the capture of fully loaded webpages, can consider the following solution.

This issue arises when minor content is loaded asynchronously, preventing PhantomJS from detecting the completion of the page. To address this, consider implementing a delay mechanism:

page.open(address, function (status) {
    if (status !== 'success') {
        console.log('Unable to load the address!');
        phantom.exit();
    } else {
        window.setTimeout(function () {
            page.render(output);
            phantom.exit();
        }, 1000); // Change timeout as required to allow sufficient time 
    }
});
Copy after login

By introducing a timeout between page loading and rendering, PhantomJS is given ample time to wait for additional resources to load. Adjust the timeout value to ensure sufficient time for complete page load before capturing the screenshot. This allows for accurate representation of dynamic elements, including ads.
