Description:

Two problems aroused here:

if (clicking == 1){      ************** } else if (clicking == 2){      ************** } else if (clicking == 3) {      ************** }else{      clicking = 0; }

a. I innitially used clicking = 1/2/3, but it failed: single = is for assigning, and double == is for comparing.

b. I changed the = into ==, but the number, according to consolog, goes “1, 2, 3, 4,  1, 2, 3, 4.” There is an extra “4.” I the realised that I shouldn’t use “else” at the last section because once it run into “else,” the clicking number has already reached “4.”

I encounter a lot problems when doing this exercise. First is adjusting the positions of the pictures. I forgot the “flex” function in css. Then I had difficulty in assigning numbers to a variable. After changing the order of the code, I succeeded in assigning right numbers to the variable each time we click the button. Then, I figured out that everything in Javascript only happens once. And everything else will rely on events. Every time an event is called, code inside that event will happen.

Getting the coding right for the animation was difficult but we got there in the end!
