This code provides a function to resize and position a browser window into a grid layout, allowing for the management of multiple browser instances in a structured manner. It uses a client object (likely Selenium) to interact with the browser and calculates window positions based on a specified grid structure.

Run example

npm run import -- "resize selenium window"

resize selenium window

var rows = 6;
var columns = 6;
var screen = {
    height: 1024 * 6,
    width: 1350 * 6
};

function getScreenSize(client) {
    return client
        .getWindowHandle()
        .then(r => client.maximizeWindow(r))
        .catch(e => {})
        .getWindowSize()
        .then(r => (screen = r))
        .catch(e => console.log(e))
}

function resizeWindow(client, i = 0) {
    i = Math.abs(i + (typeof OFFSET !== 'undefined' ? OFFSET : 0));
    var hwnd;
    return client
        .getWindowHandle()
        .then(r => client.switchToWindow((hwnd = r)))
        .then(() => typeof screen === 'undefined' ? getScreenSize() : screen)
        .catch(e => console.log(e))
        .then(screen => {
            const newPosition = {
                x: Math.floor(i % columns)
                    * Math.floor(screen.width / columns),
                y: Math.floor(i / columns % rows)
                    * Math.floor(screen.height / rows)
            };
            console.log(newPosition);
            return client.setWindowPosition(
                newPosition.x,
                newPosition.y)
        })
        .catch(e => console.log(e))
        .then(() => client.setWindowSize(
            Math.floor(screen.width / columns),
            Math.floor(screen.height / rows)))
        .catch(e => console.log(e))

This code defines a function resizeWindow that resizes and positions a browser window into a grid layout.

Here's a breakdown:

1. Initialization:

   • Sets up variables for the desired number of rows and columns in the grid.
   • Defines a screen object to store the browser window's dimensions.

2. getScreenSize Function:

   • Takes a client object (likely a Selenium WebDriver instance) as input.
   • Maximizes the browser window.
   • Retrieves the current window size and updates the screen object.

3. resizeWindow Function:

   • Takes a client object and an optional i parameter (index for grid positioning).
   • Calculates the new window position based on the grid layout and the provided index.
   • Sets the window position and size using the calculated values.
   • Logs the new position to the console.

4. Export:

   • Exports the resizeWindow function for use in other modules.
