jQuery 点击事件多次触发

我正在尝试用 Javascript 编写一个视频扑克游戏，作为了解其基础知识的一种方式，但我遇到了 jQuery 单击事件处理程序多次触发的问题。

它们附在用于下注的按钮上，并且在游戏过程中第一手牌下注时效果很好（仅触发一次）；但在第二手牌的投注中，每次按下投注或下注按钮时，它都会触发两次点击事件（因此每次按下时投注正确金额的两倍）。总体而言，当按下一次下注按钮时，点击事件被触发的次数就遵循这种模式——其中ith序列中的项用于下注ith从游戏一开始，手牌数为：1, 2, 4, 7, 11, 16, 22, 29, 37, 46，无论值多少，似乎都是 n(n+1)/2 + 1 ——而我不够聪明，无法弄清楚这一点，我用过OEIS http://oeis.org/. :)

这是正在运行的单击事件处理程序的函数；希望它很容易理解（如果没有，请告诉我，我也想在这方面做得更好）：

/** 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与此处另一个问题的解决方案类似，请告诉我（我已经查看了许多类似标题的线程，但没有找到可行的解决方案）为我）。

要确保一次仅单击操作，请使用以下命令：

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