jquery如何循环出下列数据区间的个数？

var qujian = [100,200,300,500];

var shuju =[262,44,66,55,787,151,544,32,111,21,225,6545,6654,2245,22,34,656,54,455,266,544,87,355,365,365];

qujian = [0].concat(qujian);

var data = {}

for(var i = 0;i < qujian.length - 1;i++){

    for(var j = 0;j < shuju.length; j++){

        if(shuju[j]>=qujian[i] && shuju[j]<=qujian[i+1]){

            var key = qujian[i]+'-'+qujian[i+1];

            data[key] = data[key] || [];

            data[key].push(shuju[j]);

        }

    }

}

console.log(data);

//以下是输出结果

• 0-100: (9) [44, 66, 55, 32, 21, 22, 34, 54, 87]

• 100-200: (2) [151, 111]

• 200-300: (3) [262, 225, 266]

• 300-500: (4) [455, 355, 365, 365]

qujian = [100,200,300,500];

shuju =[262,44,66,55,787,151,544,32,111,21,225,6545,6654,2245,22,34,656,54,455,266,544,87,355,365,365];

var a=0,b=0,c=0,d=0;
for(var i=0;i{
var zhi=parseint(shuju[i]);//这里需要转下数据类型，转成int型吧，

if(zhi>=0&&zhi<100)
{
a+=1；

}
