Useful code snippets for web analytics & tracking implementation

Google Tag Manager

Log pushed dataLayer events to console

(function(){
    const originalPush = window.dataLayer.push
    window.dataLayer.push = (msg) => {
        console.log(msg);
        originalPush(msg);
    }
})();

Bulk-select (e. g. to delete) variables

Go to the variables overview in Google Tag Manager and execute the following code in your browser's JS console after adding the list of variable names to the rowCaptions array.

const rowCaptions = [
    // Add list of variable names here
];

function clickCheckboxes() {
    let clickedCount = 0;

    rowCaptions.forEach(caption => {
        // Find the row containing the caption
        const row = Array.from(document.querySelectorAll('tr[gtm-table-row]')).find(row => 
            row.textContent.includes(caption)
        );

        if (row) {
            // Find the checkbox within the row
            const checkbox = row.querySelector('i[role="checkbox"]');
            if (checkbox) {
                checkbox.click();
                clickedCount++;
                console.log(`Clicked checkbox for: ${caption}`);
            } else {
                console.log(`Checkbox not found for: ${caption}`);
            }
        } else {
            console.log(`Row not found for: ${caption}`);
        }
    });

    console.log(`Finished. Clicked ${clickedCount} checkboxes.`);
}

// Run the function
clickCheckboxes();

Google Analytics

List all GA trackers

ga
.getAll()
.forEach(tracker =>
	console.log(
		`name: ${tracker.get("name")} trackingId: ${tracker.get(
			"trackingId"
		)} cookieDomain: ${tracker.get(
			"cookieDomain"
		)} allowLinker: ${tracker.get("allowLinker")}`
	)
);
