Why Doesn't jQuery Click() Function on Unbound Links Trigger the Default Browser Action?

jQuery Click() Behavior on Unbound Links

In this query, we explore the behavior of jQuery's click() function when applied to an link without a previously bound event handler.

It is observed that calling $('a').click() without a prior bind() or click() event binding has no effect. This raises the question of why this occurs and whether it is due to an error.

Analysis:

Upon investigation, it was discovered that the aforementioned behavior does not actually occur. The lack of response observed previously was likely due to an isolated incident.

In the absence of a custom event handler, the click() function merely triggers the browser's default click behavior. However, if an event handler is defined, the handler is executed first, even if it does not perform any action. This behavior ensures that the default action is not executed until after the event handler has completed.

Conclusion:

It is not possible to "fake" clicks in the browser. jQuery's click() function simply calls the event handler defined for the element. Alternatively, one can directly use document.getElementById(...).click() to trigger the click event in vanilla JavaScript.
