Example: Check Prime Number // program to check if a number is prime or not // take input from the user const number = parseInt(prompt("Enter a positive number: ")); let isPrime = true; // check if number is equal to 1 if (number === 1) { console.log("1 is neither prime ...
// program to find the factors of an integer // take input const num = prompt('Enter a positive number: '); console.log(`The factors of ${num} is:`); // looping through 1 to num for(let i = 1; i <= num; i++) { // check if number is a factor if(num % i == 0)...
那么,需要一个MouseOver触发器。只要设置onMouseOver属性(attribute)为“JavaScript program”,把这一属性加入定义链接的标记:<A HREF="URL" onMouseOver="JavaScript program"> 这是一个链接 </A>这样在用户浏览该页时,当鼠标移到链接的上方,就会触发MouseOver事件,从而执行onMouseOver属性指定的“JavaScript program”程...
