Today I was teaching software project management to students, and I found that the students wanted to sleep. I had an idea and wrote a small game for everyone, let’s guess together~

Guess
<script> //Randomly generate a random integer // Rounding Random number (0-1) var num = Math.round(Math.random()*1000); //Define a flag variable var falg=true; //Define a variable to count the number of guesses var count=1; document.write(" "); //Execute while loop while(falg){ if(count<=10){ Compare the input content with the generated random number Document. write("This is your "+count+" chance. The number you entered this time is "+inputnum+", the number you entered is too big "); Situation: 2) The input number is smaller than the generated random number. The prompt is "too small" The number entered this time is "+inputnum+", the number you entered is too small "); count++; Set the flag position as false; if (inputnum == NUM) { if (count & lt; = 3) { // Output a sentence, Alert ("You super cow X, guess! "); Correct! "); ){ //Output a sentence, Then, t ALERT ("I dizzy, I didn't guess 10 times, how can I do it?!"); </head> <body> </body> </html> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http: //www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> <title>Guess it</title> <script> // Randomly generate a random integer // Rounding random number (0-1) var num = Math.round(Math.random()*1000); //Define a flag variable var falg=true; //Definition A variable, counting the number of guesses var count=1; document.write(" "); //Execute the while loop while(falg){ if(count<=10){ //The first step is to accept the content input by the user var inputnum=prompt("Please enter the number you want to guess!" ,1); //The second step is to compare the content input by the user with the generated random number //Three situations: 1) The input number is greater than the generated random number and the prompt is "too big" if(inputnum&gt ;num){ //Output a sentence, document.write("This is your "+count+" chance, the number you entered this time is "+inputnum+", the number you entered is too big "); Count++; } //Three situations: 2) The input number is less than the generated random number.
