For every click an event will be triggered and that event contains all the info about the element. So, we obviously have to catch that event to get the element info and it can be easily done with JS.

When clicked any element then it triggers an event and we can find the element details using the event.target.

Following is the example code with both jQuery and without jQuery.

With jQuery

$(document).click(function(event) {
    
    // The following the line of code gets the text of an element.
    // Event.target gets the element details
    var textData = $(event.target).text();
});

Without jQuery

document.addEventListener('click', function(e) {
    e = e || window.event;
    var targetElement = e.target || e.srcElement,
        text = targetElement.textContent || targetElement.innerText;   
}, false);

The above event listeners might not work in some of the browsers such as the less than IE9. So, instead of addEventListener() we might need to use the attachEvent().
