哪个帮个忙,把PHP函数修改为JS函数,谢谢!
function bmrs($weight=0,$sex=1,$age){


switch ($age) {

case $age>=0 and $age<3:


$x=array(1=>array(60.9,-54),2=>array(61.0,-51));

$y=1;


break;



case $age>=3 and $age<10:

$x=array(1=>array(22.7,495),2=>array(22.5,499));
$y=1;

break;


case $age>=10 and $age<18:

$x=array(1=>array(17.5,651),2=>array(12.2,746));

$y=1;
break;

case $age>=10 and $age<18:

$x=array(1=>array(17.5,651),2=>array(12.2,746));
$y=0.95;

break;

case $age>=18 and $age<30:

$x=array(1=>array(15.3,679),2=>array(14.7,496));
$y=0.95;

break;

case $age>=30 and $age<60:

$x=array(1=>array(11.6,879),2=>array(8.7,829));
$y=0.95;

break;

case $age>=60:

$x=array(1=>array(13.5,487),2=>array(10.5,596));
$y=0.95;

break;

default:
break;
}


return ceil(($x[$sex][0]*$weight+$x[$sex][1])*$y); //对浮点数进行四舍五入

}

自带参数这几个,前面二个是默认值吗?$weight=0,$sex=1,$age

这二个代码,修改为JS,遇到了难度:

case $age>=0 and $age<3:
$x=array(1=>array(60.9,-54),2=>array(61.0,-51));


哪位帮个忙,把它修改为JavaScript的,谢谢。



------解决方案--------------------
JScript code
function bmrs(weight,sex,age){
    var x=new Array(2),y=null;

    switch (true)
    {

        case age>=0 && age<3:


            x[1]=new Array(60.9,-54),x[2]=new Array(61.0,-51);

            y=1;
            break;



        case age>=3 && age<10:

            x[1]=new Array(22.7,495),x[2]=new Array(22.5,499);
            y=1;

            break;


        case age>=10 && age<18:

            x[1]=new Array(17.5,651),x[2]=new Array(12.2,746);

            y=1;
            break;

        case age>=10 && age<18:

            x[1]=new Array(17.5,651),x[2]=new Array(12.2,746);
            y=0.95;

            break;

        case age>=18 && age<30:

            x[1]=new Array(15.3,679),x[2]=new Array(14.7,496);
            y=0.95;

            break;

        case age>=30 && age<60:

            x[1]=new Array(11.6,879),x[2]=new Array(8.7,829);
            y=0.95;

            break;

        case age>=60:

            x[1]=new Array(13.5,487),x[2]=new Array(10.5,596);
            y=0.95;

            break;

        default:
           break;
    }

    return Math.ceil((x[1][0]*weight+x[1][1])*y); 

}
