输入对象和数量制造批量假数据

function createData(obj,num){
    var list=[];
    for(var i=1;i<=num;i++){
        var newObj={};
        for(var key in obj){
            if(obj[key]=="number"){
                newObj[key]=i
            }else{
                newObj[key]=Math.round(Math.random()*1000000)
            }
        }
        list.push(newObj)
    }
    return list;
}
