数组的截取合并和数组对象的排序

$(function(){

$.get("http://localhost:3000/number",function(data){

console.log(data)

var data=data

var a=data.slice(0,4)//截取数组的前4项

b=data.slice(-4)//截取数组的后4项

var c = a.concat(b) //合并2个截取数组生产一个新数组

c.sort(compare('AMPLITUDE')); //调用函数给新数组以AMPLITUDE排序

console.log(c)

})

})

var student = [{"name":"lisi","age":18,"sex":"male"},

{"name":"zhangsan","age":17,"sex":"female"},

{"name":"wangwu","age":21,"sex":"shemale"}];

student.sort(compare("age"));

console.dir(student);

function compare(protoTypeName) {

return function(object1,object2){

var val1 = object1[protoTypeName];

var val2 = object2[protoTypeName];

if(val1<val2){

return -1;

}else if(val1>val2){

return 1;

}else{

return 0;

}

}

}
