随机 的onclick

问题描述 投票：0回答：4

我正在尝试制作一个简单的游戏

  • 你从9圈开始
  • 当您点击带有较粗边框的圆圈时，它会增加一个分数并导致随机绘制新圆圈。

我已经在计算东西，但我有一个问题，因为无论你点击哪里（我的意思是div），它总结了点数。我不知道如何停用没有较粗边框的div。

请告诉我这是否是一个很好的编程方法。

您可以将当前有边界的div编号存储在变量中，每次调用click函数时，都可以检查相同的div编号是否触发了此函数调用。

以下是您修改后的代码：

window.onload = start;

function start() {
  var div_value = "";

  for (i = 0; i < 9; i++) {
    var element = "div_number" + i;
    div_value = div_value + '<div class="point" id="' + element + '" onclick="c(' + i + ')"> Klik </div>';

    if ((i + 1) % 3 == 0) {
      div_value = div_value + '<div style="clear:both;"> </div>';
    }

  }

  document.getElementsByClassName("points")[0].innerHTML = div_value;

  esthetic();
  random_show();
}

currDiv = 0;
// IT SHOWS 1 RANDOM DIV TO START THE GAME
function random_show() {
  var a = Math.floor((Math.random() * 8));
  currDiv = a; // assign current bordered div
  var x = document.getElementById("div_number" + a).style.border = "10px       dotted";
}

var liczby = [];
// IT DROWN LOTS AND COUNT THE SCORE
function c(i) {

  if (parseInt(i) == currDiv) { // check if the current div clicked is the bordered div

    var a = Math.floor((Math.random() * 8));
    this.i = a;
    var z = document.getElementById("div_number" + i);
    var y = document.getElementById("div_number" + a);

    currDiv = a; // change it to the current bordered div


    if (y.style.border = "10px dotted") {
      z.style.border = "5px dotted";
      liczby.push(i);
    } else {
      y.style.border = "8px solid";
    }

    var x = document.getElementById("zliczenie").innerHTML = liczby.length;

  }


}


// IT GIVES EVERY DIV INITIAL style.border 
function esthetic() {
  var x = document.getElementsByClassName("point");
  for (i = 0; i < 9; i++) {
    x[i].style.border = "5px dotted";

  }
}

将样式保存在.html文件中的.css文件和html标记以及.js文件中的代码中始终是一种好习惯。

另外，为了检查元素上是否存在特定样式，您应该检查该元素是否在其类列表中具有特定类。参考：https://developer.mozilla.org/en/docs/Web/API/Element/classList

在.css中创建新类：

.boldCircle {
    border: 10px dotted;
}

在您的代码中只需：

if(y.classlist.contains("boldCircle")) {
    // Do what you want
}

我想指出的另一件事是if条件中的相等性。您应该使用'=='而不是'='。 '='是赋值运算符，总是求值为true。

if (y.style.border == "10px dotted") {
    // Do what you want
}

在@DeepakKumar建议的基础上，我还会考虑使用类将元素标记为活动目标。然后，您的点击事件处理程序可以检查它并根据需要增加点数/管理您的数组。

我还简化了一些代码，以便为这个沙箱更好地格式化它。

// =====================
// Initialize the game
// =====================
function start() {
  var divTemplate = '<div id="%1%" class="point" data-index="%2%" onclick="c(event)"> Klik </div>';
  var clearTemplate = '<div style="clear:both;"> </div>';
  var elPoints = document.getElementsByClassName("points")[0];

  var div_value = "";

  for (i = 0; i < 9; i++) {
    div_value += divTemplate
                    .replace("%1%", "div_number" + i)
                    .replace("%2%", i);

    if ((i + 1) % 3 == 0) { div_value += clearTemplate; }
  }

  elPoints.innerHTML = div_value;

  liczby = [];
  random_show();
}
// =====================

// =====================
// Set one div as the target
// =====================
function random_show() {
  var a = Math.floor((Math.random() * 8));
  var elCurrentTarget = document.querySelector(".point.target");
  var elNewTarget = document.getElementById("div_number" + a);

  if (elCurrentTarget) { elCurrentTarget.classList.remove("target"); }
  elNewTarget.classList.add("target");
}
// =====================

// =====================
// If the target div was clicked increment the score
// reset the board.
// =====================
function c(event) {
  var elTarget = event.target;
  var elScore = document.getElementById("zliczenie");

  if (elTarget.classList.contains("target")) {
    liczby.push(elTarget.getAttribute("data-index"));
    elScore.innerHTML = liczby.length;
  }

  random_show();
}
// =====================

var liczby = [];
window.onload = start;
.wynik {
  border: solid 1px blue;
}

.points {
  width: calc(140px * 3);
  margin: 5px auto;
}

.point {
  width: 60px;
  height: 60px;
  border: solid 1px #000;
  border-radius: 100%;
  text-align: center;
  cursor: pointer;

以下代码表示“如果您点击粗圆，则得分+ 1，否则得分为1”：

score += i == winning ? +1 : -1;

有关详细信息，请参阅conditional operator。

关于随机性的帖子：https://stackoverflow.com/a/32395535/1636522。

var boardEl = document.getElementById("board"), 
    scoreEl = document.getElementById("score"), 
    indexOf = Array.prototype.indexOf, 
    winning = 0, 
    score = 0;

scoreEl.textContent = "( " + score + " )";
boardEl.innerHTML = new Array(10).join("<a href=\"#\"></a>");
boardEl.childNodes[winning].setAttribute("class", "winning");

boardEl.onclick = function (ev) {
  var i, rdm, winningEl;
  ev.preventDefault();
  if (ev.target.parentNode == boardEl) {
    i = indexOf.call(boardEl.childNodes, ev.target);
    score += i == winning ? +1 : -1;
    winningEl = boardEl.childNodes[winning];
    winningEl.setAttribute("class", "");
    rdm = Math.floor(Math.random() * 8);
    winning = rdm >= winning ? rdm + 1 : rdm;
    winningEl = boardEl.childNodes[winning];
    winningEl.setAttribute("class", "winning");
    scoreEl.textContent = "( " + score + " )";
  }
};
#board, #score {
