Question

我现在有这个：

$from = $_POST['from'];
    $q = mysql_query("SELECT * FROM puzzles LIMIT $from,1");

    while(($row=mysql_fetch_assoc($q))!=false){
     $result = array('description' => $row['description'], 'id' => $row['id']);
     echo json_encode($result);

问题是，我得到的绿色比蓝色更多，例如：var generateIcons = function(playtime, players) { var count = playtime / 2; icons = []; for (var i = 1; i <= count; i++) { if (i % 8 === 0 && players === 8) { icons.push("cyan"); } else if (i % 7 === 0 && players >= 7) { icons.push("violet"); } else if (i % 6 === 0 && players >= 6) { icons.push("orange"); } else if (i % 5 === 0 && players >= 5) { icons.push("black"); } else if (i % 4 === 0 && players >= 4) { icons.push("gold"); } else if (i % 3 === 0 && players >= 3) { icons.push("red"); } else if (i % 2 === 0 && players >= 2) { icons.push("blue"); } else { icons.push("green"); } } }; 如何获得〜等量的绿色，蓝色，红色，金色？

Answer 1

所以，如果我理解你的问题，这应该有效：

＆＃13;

var generateIcons = function(playtime, players) {
    var count = playtime / 2;
    icons = [];
    colors = ["cyan", "violet", "orange", "black", "gold", "red", "blue", "green"];
    for (var i = 0; i < count; i++) {
    	icons.push(colors[i % players]);
    }
    return icons;
};

console.log(generateIcons(60, 4));

检查该解决方案是否满足您：）

var generateIcons = function(playtime, players) {
            var count = playtime / 2;
            icons = [];
            var randomNumber;

            for (var i = 1; i <= count; i++) {
                randomNumber = Math.floor((Math.random() *  players) + 1); //generate random number from <1, players> probability for each color should be ~equal ;)
                if(randomNumber == 1)
                {
                    icons.push("green");
                }
                else if (randomNumber == 2)
                {
                    icons.push("blue");
                }
                else if (randomNumber == 3)
                {
                    icons.push("red");
                }
                else if (randomNumber == 4)
                {
                    icons.push("gold");
                }
                else if (randomNumber == 5)
                {
                    icons.push("black");
                }
                else if (randomNumber == 6)
                {
                    icons.push("orange");
                }
                else if (randomNumber == 7)
                {
                    icons.push("violet");
                }
                else
                {
                    icons.push("cyan");
                }

            }

        }

generateIcons(60,4);

console.log(icons);
