Exploring the setTimeout function in JavaScript

As I understand it, the setTimeout function creates a new thread that waits for x milliseconds before executing the JavaScript function.

setTimeout(functionName, timeInms);

My question is: Is there a way to instruct it to run after all other JS on the page has finished executing? This timing would vary based on the amount of JS present and cannot be determined by a set number of milliseconds.

This query pertains to a larger issue that I previously discussed here:

link text

The problem lies in ScriptManager's lack of execution order guarantee, requiring me to run the EndScript function at the very end. While using setTimeout somewhat solves this, it isn't entirely accurate due to variations in the JS content across pages.

Answer №1

Did you know that Javascript is a single-threaded language?

In JavaScript, if you set a timer that expires while your code is still running, the timer function will not execute until the code has finished running.

UPDATE: Just to be clear, the timer will only execute the function after it "rings" and the JS thread is free from any code execution.

Keep in mind that it will wait for all of the code to finish running, not just specific files.
