我有来自josex2r Jquery老虎机

的代码

此代码通过显示该活动插槽的数量（js代码）显示当前处于活动状态

<div id="machine1" class="slotMachine">
<div class="slot slot1"></div>
<div class="slot slot2"></div>
<div class="slot slot3"></div>
<div class="slot slot4"></div>
<div class="slot slot5"></div>
<div class="slot slot6"></div>
</div>

<div style="clear:both;">
<div id="machine1Result" class="slotMachine noBorder" style="text-align:left">Index: 0</div>
<div id="machine2Result" class="slotMachine noBorder" style="text-align:left">Index: 1</div>
<div id="machine3Result" class="slotMachine noBorder" style="text-align:left">Index: 2</div>
<div class="slotMachine noBorder"></div>
</div>

function onComplete($el, active){
        switch($el[0].id){
                case 'machine1':
                    $("#machine1Result").text("Index: "+active.index);
                    break;
                case 'machine2':
                    $("#machine2Result").text("Index: "+active.index);
                    break;
                case 'machine3':
                    $("#machine3Result").text("Index: "+active.index);
                    break;
            }
        }

目标是......一旦用户得到相同的结果说“777”然后改变一些div的背景。从这里实现相同的目标：Link

将3个结果与if == 777一起使用css()来改变背景

function onComplete($el, active){

    var m1Index;
    var m2Index;
    var m3Index;

    switch($el[0].id) {
        case 'machine1':
            m1Index = active.index;
            $("#machine1Result").text("Index: "+ m1Index );                    
            break;
        case 'machine2':
            m2Index = active.index;
            $("#machine2Result").text("Index: " + m2Index );
            break;
        case 'machine3':
            m3Index = active.index;
            $("#machine3Result").text("Index: "+ m3Index  );
            break;
    }

     if (m1Index & m2Index & m3Index) {         

        if ("" + m1Index + m2Index + m3Index == "777") { 
            $('.someDiv').css({"backgroundColor": "green"});
        }

     }

}

首先检查所有三个索引是否存在，然后检查字符串组合是否等于777

将""添加到if ("" +会强制将三个数字强制转换为字符串
