[Dhruv-Tech-Apps]

Page load.

When we type URL and hit enter / refresh page. A Request from browser is sent to server and server sent back html page which is loaded in browser . It loaded in chunks.

• of page is loaded first.
• HTML structure (DOM) is loaded Document load
• Any script and style sheet is loaded which is include in tag of html page.
• Once all above things are loaded it means page is loaded completely. It takes just sec to load everything. Window load

Extension load.

Once page is loaded completely extension is loaded.

• Auto Clicker extension loads required file.
• It checks configuration to match URL of page. and if any configuration matched it takes that configuration and execute all its Action one by one.

You can load extension faster by loading it once Document is loaded by switching load option from Configuration Setting

Extension Steps.

• It takes 1 Action and find Element which matched Element Finder
• Negative Scenario 👎 If Element is not found it will Retry for N no of times which we have set in Global Settings.
  • If Element is not found after N try also there are three option
    • Stop
    • Skip Action
    • Refresh Page
• Positive Scenario 👍 If Element is found. It take value which is configured and process action.
• Once All Action are completed extension is stopped (Inactive).

If any new changes occur in page extension don't perform any Action on it until page is refreshed.

Keep Extension Alive

There are three ways extension is alive

Scenario 1

You want extension to keep looking for and element until it appear without refreshing page. Set Retry to -2 under Global settings and Retry Interval as 1 or above as per your requirement. In this case if Extension don't find required Element within Web page it will keep on trying to find the that element in endless loop because of '-2' which equals infinite in our extension. Again When Extension find that element it will perform normal flow and stop once action are done.

You can use LocationCommand::reload LocationCommand Value as last Action which will reload page once all action are completed this way it will start again with page load and start looking for element again.

Scenario 2

This time you have that element in page but its value is not one which you require e.g. Out of Stock -> Buy or Price $50 -> $40. You want to click on Buy button when price goes down or product is available. And update on site happening in background (Async) without page is refreshed or loaded.

You can make use of Addon here.

Element Finder - of Element which changes. Under Value you need to set value which will get compared. Select condition accordingly.
