jQuery单击事件触发多次

javascript

我试图用Javascript编写视频扑克游戏,以降低其基础知识,但是我遇到了一个问题,其中jQuery click事件处理程序多次触发。

它们被附加到用于下注的按钮上,并且对于在游戏过程中第一手下注(仅触发一次)非常有效。但是在秒针下注中,每次按下一个下注或下注按钮都会触发两次点击事件(因此,每次按下正确的赌注量是两次)。总体而言,在按一次下注按钮时,触发单击事件的次数遵循此模式序列的第i个术语用于从游戏开始时下注第i个手:,7、11、16、22、29、37、46,无论值多少,它看起来都是n(n + 1)/ 2+1-而且我不够聪明,无法弄清楚,我使用OEIS。

这是正在起作用的click事件处理程序的函数;希望它很容易理解(让我知道是否可以,我也想做得更好):

/** The following function keeps track of bet buttons that are pressed, until place button is pressed to place bet. **/
function pushingBetButtons() {
    $("#money").text("Money left: $" + player.money); // displays money player has left

    $(".bet").click(function() {
        var amount = 0; // holds the amount of money the player bet on this click
        if($(this).attr("id") == "bet1") { // the player just bet $1
            amount = 1;
        } else if($(this).attr("id") == "bet5") { // etc.
            amount = 5;
        } else if($(this).attr("id") == "bet25") {
            amount = 25;
        } else if($(this).attr("id") == "bet100") {
            amount = 100;
        } else if($(this).attr("id") == "bet500") {
            amount = 500;
        } else if($(this).attr("id") == "bet1000") {
            amount = 1000;
        }
        if(player.money >= amount) { // check whether the player has this much to bet
            player.bet += amount; // add what was just bet by clicking that button to the total bet on this hand
            player.money -= amount; // and, of course, subtract it from player's current pot
            $("#money").text("Money left: $" + player.money); // then redisplay what the player has left
        } else {
            alert("You don't have $" + amount + " to bet.");
        }
    });

    $("#place").click(function() {
        if(player.bet == 0) { // player didn't bet anything on this hand
            alert("Please place a bet first.");
        } else {
            $("#card_para").css("display", "block"); // now show the cards
            $(".card").bind("click", cardClicked); // and set up the event handler for the cards
            $("#bet_buttons_para").css("display", "none"); // hide the bet buttons and place bet button
            $("#redraw").css("display", "block"); // and reshow the button for redrawing the hand
            player.bet = 0; // reset the bet for betting on the next hand
            drawNewHand(); // draw the cards
        }
    });
}

如果您有任何想法或建议,或者我的问题的解决方案是否类似于此处的另一个问题的解决方案,请让我知道(我看过许多标题相似的主题,也没有运气找到可行的解决方案为了我)。

要确保一次“仅单击”操作,请使用以下命令:

$(".bet").unbind().click(function() {
    //Stuff
});
