Javascript jQuery单击事件多次触发

我正试图用Javascript编写一个视频Flutter 克游戏，以此来了解它的基本知识，但我遇到了一个问题，jQuery单击事件处理程序会多次触发.

它们与下注按钮相连，在游戏中第一手下注(仅开火一次)效果良好；但是，在下注第二手牌时，它会在每次按下下注或下注按钮时触发两次点击事件(因此每次按下的正确下注金额是正确下注金额的两倍).总的来说，当按下一次下注按钮时，点击事件的触发次数遵循这种模式——序列中的ith项用于从游戏开始时下注ith手牌:1、2、4、7、11、16、22、29、37、46、，这似乎是n(n+1)/2+1，不管它值多少——我还没有聪明到能弄明白这一点，我用了OEIS.:)

这是一个带有点击事件处理程序的函数；希望这很容易理解(如果不是，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
        }
    });
}
