JavaScript Event Delay

JavaScript is one of the few programming languages that allow developers to delay functions and events. The commands that delay functions and events are functions that wait for the input of the user. The delay commands will let different functions and even local configurations (such as local file association) to execute before the client side interaction starts.

It is a very simple code that uses “setTimeout” as its basic command for proper execution. The commands that deal with function delays have already been extensively discussed but the delay in terms of events were not extensively covered.

Benefits of Event Delay

The advantage of event delay could be compared to functional delays in JavaScript. The end goal of event delay is to let other functions execute before they an event could start. When an event delay is properly implemented, the local gadget will not experience any lag time as functions and events will not be executed at the same time.

This will also enable the developers to build another interaction within the delay. For example, the first executed function will yield a result and that result could still interact with the delayed function. This is actually pushing the delay function but it could be done.

Comparing Function with Event Delay

Delay in functions would enable developers to properly set the whole application without dragging the local gadget or would be feasible when executing in weak internet connection. Although the difference is only in milliseconds, developers should be able to plot out the functions and execute them according to the length of delay.

On the other hand, event delay only happens once but will influence the entire application. An event could be as simple as changing the interface or even refresh. Event can’t just be executed based on the delay of clicks but could also be based on the idle time of the interaction. That means events could happen at anytime of the function or user interaction.

Lightweight with Ease of Configuration

The challenge in dealing with function delay is that the coding which could take up a lot of time. This is especially true when developers want to string the functions together to build a very powerful function. This would however require a powerful gadget so that it could execute the function faster.

On the other hand, when an event delay is executed, the entire application will not be affected. The reason for this ease is the simple coding it will require. In gist, developers could just add a simple “setTimeout” before the event would happen.

By adding this code, the event would be delayed and the actual execution of functions could happen first or the event delay would just wait for idle time before they could be executed.

Event delay is a very simple yet very useful function that could be used by developers in their Ajax based applications. By carefully considering the functions before the execution of event delay, developers can now build an application wherein the interaction is more than just the click from its users.
