我還在使用JavaScript。我試圖製作一個包含2個按鈕的程序,一旦點擊一個按鈕,它會創建一個隨機數。程序沒有運行
問題是,當我試圖比較它們時,它沒有顯示哪一個更大。首先,我認爲問題是變量不是全局的,但它沒有改變任何東西。
有人可以幫我找到問題嗎?
這裏是的JavaScript代碼:
var par1 = document.getElementById("para1");
var par2 = document.getElementById("para2");
var winner = document.getElementById("win");
function button1() {
num1 = Math.floor(Math.random() * 7);
par1.innerHTML = num1;
}
function button2() {
num2 = Math.floor(Math.random() * 7);
par2.innerHTML = num2;
}
if (num1 > num2) {
winner.innerHTML = "the winner is player 1";
} else {
winner.innerHTML = "the winner is player 2";
}
