    }
    .loMainBox{

        cursor: pointer;
    }
    .setBgColor{

    }

js部分

/**
     * 选择图片
     * **/
    function show(num,idName){
        var loBox=document.getElementById(idName);
        loBox.style.backgroundImage = 'url(../images/' + num + '.jpg';
    }
    /**
     * 比较大小 规则
     * * */
    function bijiao() {
        var loBox = document.getElementById('loBox');
        var loBox2 = document.getElementById('loBox2');
        var loBoxUrl = parseInt((loBox.style.backgroundImage).match(/\d/));// '\d'查找数字
        var loBoxUrl2 = parseInt((loBox2.style.backgroundImage).match(/\d/));
        if ((loBoxUrl == 0 && loBoxUrl2 == 0) ||(loBoxUrl == 1 && loBoxUrl2 == 1) ||(loBoxUrl == 2 && loBoxUrl2 == 2)) {
            changeBackgroundColer('red','red');
        } else if ((loBoxUrl == 1 && loBoxUrl2 == 0)||(loBoxUrl == 2 && loBoxUrl2 == 1)||(loBoxUrl == 0 && loBoxUrl2 == 2)) {
            changeBackgroundColer('white','skyblue');
        } else {
            changeBackgroundColer('skyblue','white');
        }
    }
    /**
     * 颜色变化
     */
    function changeBackgroundColer(color1,color2){
        document.getElementById('loLeftBox').style.backgroundColor = color1;
        document.getElementById('loRightBox').style.backgroundColor = color2;
    }

效果如下：
