javascript - 限制在 JS 中调用某些函数的次数

Question

好的，我有一个以循环模式运行的小脚本。是来赌的这是想法:我抛硬币无限次(循环)，双方都有 50/50 的机会。但是，在某些时候，我会在“数字端”行中获得 5 次:...，head，number，head，NUMBER，NUMBER，NUMBER，NUMBER，NUMBER，...如果在“数字端”行中获得 5 次，我需要限制脚本调用函数。就我而言，我有函数 multiply() 并且有时会调用该函数。因此，我需要限制调用 multiply() 函数的次数，例如。 5 或 4..因此，如果脚本连续调用函数 multiply() 5 次，它会做一些事情(例如显示警报或其他事情)。这是脚本:

var startValue = '0.00000001', // Don't lower the decimal point more than 4x of current balance
            stopPercentage = 0.001, // In %. I wouldn't recommend going past 0.08
            maxWait = 500, // In milliseconds
            stopped = false,
            stopBefore = 3; // In minutes
     
    var $loButton = $('#double_your_btc_bet_lo_button'),
                    $hiButton = $('#double_your_btc_bet_hi_button');
     
    function multiply(){
            var current = $('#double_your_btc_stake').val();
            var multiply = (current * 2).toFixed(8);
            $('#double_your_btc_stake').val(multiply);
    }
     
    function getRandomWait(){
            var wait = Math.floor(Math.random() * maxWait ) + 100;
     
            console.log('Waiting for ' + wait + 'ms before next bet.');
     
            return wait ;
    }
     
    function startGame(){
            console.log('Game started!');
            reset();
            $loButton.trigger('click');
    }
     
    function stopGame(){
            console.log('Game will stop soon! Let me finish.');
            stopped = true;
    }
     
    function reset(){
            $('#double_your_btc_stake').val(startValue);
    }
     
    // quick and dirty hack if you have very little bitcoins like 0.0000001
    function deexponentize(number){
            return number * 1000000;
    }
     
    function iHaveEnoughMoni(){
            var balance = deexponentize(parseFloat($('#balance').text()));
            var current = deexponentize($('#double_your_btc_stake').val());
     
            return ((balance*2)/100) * (current*2) > stopPercentage/100;
    }
     
    function stopBeforeRedirect(){
            var minutes = parseInt($('title').text());
     
            if( minutes < stopBefore )
            {
                    console.log('Approaching redirect! Stop the game so we don\'t get redirected while loosing.');
                    stopGame();
     
                    return true;
            }
     
            return false;
    }
     
    // Unbind old shit
    $('#double_your_btc_bet_lose').unbind();
    $('#double_your_btc_bet_win').unbind();
     
    // Loser
    $('#double_your_btc_bet_lose').bind("DOMSubtreeModified",function(event){
            if( $(event.currentTarget).is(':contains("lose")') )
            {
                    console.log('You LOST! Multiplying your bet and betting again.');
                   
                    multiply();
     
                    setTimeout(function(){
                            $loButton.trigger('click');
                    }, getRandomWait());
     
                    //$loButton.trigger('click');
            }
    });
     
    // Winner
    $('#double_your_btc_bet_win').bind("DOMSubtreeModified",function(event){
            if( $(event.currentTarget).is(':contains("win")') )
            {
                    if( stopBeforeRedirect() )
                    {
                            return;
                    }
     
                    if( iHaveEnoughMoni() )
                    {
                            console.log('You WON! But don\'t be greedy. Restarting!');
     
                            reset();
     
                            if( stopped )
                            {
                                    stopped = false;
                                    return false;
                            }
                    }
                    else
                    {
                            console.log('You WON! Betting again');
                    }
     
                    setTimeout(function(){
                            $loButton.trigger('click');
                    }, getRandomWait());
            }
    });

如果在“失败”行中获得 5 次，我需要它来停止越来越多的失分，因为如果失败，脚本总是乘以 2。如果输了，脚本必须成倍增加，这是赌博的规则:)

创建全局变量:

var startValue = '0.00000001', // Don't lower the decimal point more than 4x of current balance
            stopPercentage = 0.001, // In %. I wouldn't recommend going past 0.08
            maxWait = 500, // In milliseconds
            stopped = false,
            stopBefore = 3, // In minutes
            multiplyCalls = 0; // <--- Added this global

添加到变量和 If 到测试值

 function multiply(){
            if(multiplyCalls <= 5){ // test multiply
                var current = $('#double_your_btc_stake').val();
                var multiply = (current * 2).toFixed(8);
                $('#double_your_btc_stake').val(multiply);
                multiplyCalls++; // increment
            }else{
                console.log('you lost');
            }
    }

在游戏重置时重置变量

function reset(){
    $('#double_your_btc_stake').val(startValue);
    multiplyCalls = 0; // reset value
}
