How to find page load completed

[yureshwar ravuri]

Hi,

We are working on an Open Source Chrome extension: Digital Assistant Client

We have a script which invokes clicks on web pages.
We record a sequence of clicks as a 'flow' or 'task'. i.e. After the first click is invoked, we wait 5 s for the page to load and then invoke the 2nd click.

setTimeout(function(){UDAPluginSDK.showhtml();}, 5000);

Now, instead of waiting for 5s, we want to explore if we can invoke the 2nd click as soon as the page is loaded. We tried using "onPageLoad" but we realised that this does not work for modern single page (responsive) applications. i.e. we don't know when the js has finished executing.

window.addEventListener('load', (event) => {
   setTimeout(function (){
      UDAPluginSDK.modifybodyhtml();
   },2000);
});

Thanks & Regards,

Hi, 

I would suggest make use the following manifest tags. Content script gains control when DOM is ready.

  "content_scripts": [

    {

      "run_at": "document_end",

      "all_frames": true

    }

  ],

Best regards,

Sergey Gorin

Hi Sergey,

Thanks for your reply. I have used the run_at already in the extension. I am talking about single page applications which has xmlhttp requests which needs to fetch the dynamic data and then render the page. How do we detect such js executions too are completed when we are navigating the user automatically.

If the history is changing, you may be able to use an `onpopstate`
handler to detect page changes in a single-page application:
