A web page that uses jQuery and has a button with id startBu

A web page that uses jQuery and has a button with id \"startButton\" loads in the following JavaScript code:

If the page loads and then the user presses the button, a series of alerts will pop up. Indicate the order in which the alerts pop up.

Possible Colors: Orange, Blue, red, brown, green

Solution

Please find the alert pop up order below:

1) orange

2) red

3) brown, and

4) blue (upon start button click)

Here while loading the web page along with this given javascript it will first load and execute the alert with color Orange as it is the first line in the code, then it will store a function to the start variable. Then the jquery code which loads automatically when the whole page is loaded, so while executing the jquery code inside the self starting function, it will first give an alert with color Red, then it will declare a jquery code that listens to the click action of html element with id = startButton; here it will just assigns the listener only, but won\'t excute it untill the button is pressed. Thus after assigning the listener, it will give the next alert with color Brown, then the code execution is done. After that whenever we pressed the startButton, then it will invoke the function start, thus inside that function it will give an alert with color Blue.
