充分利用对象文本只值

Question

从这个问题你打算在：Getting first object from javascript litteral

是否可以从一组名字只得到值：值对？因此，可以说，我们有对象的列表，具有任意数量的值，每一个对象：

var items = [ 
    {name:"Foo", age:16, gender:"m"}, 
    {name:"Bar", age:17, gender:"f"}, 
    {name:"foo", age:16, gender:"m"}, 
    {name:"bar", age:18, gender:"m"}, 
    {name:"foobar", age:18, gender:"f"}, 
    {name:"barfoo", age:20, gender:"f"} 
]; 

我怎么能回到像一个列表：

var items = [ 
    ["Foo", 16, "m"], 
    ["Bar", 17, "f"], 
    ["foo", 16, "m"], 
    ["bar", 18, "m"], 
    ["foobar", 18, "f"], 
    ["barfoo", 20, "f"] 
]; 

我都试过，但不知道是否有一个更好的方式来做到这一点。

Array.prototype.getValues = function() { 
    if(typeof(this[0]) != typeof({})) 
     throw "Array values are expected to be == typeof({})"; 
    var items = []; 
    for (var i = 0; i < this.length; i++) { 
     var r = []; 
     for (var l in this[i]) { 
      r.push(this[i][l]); 
     } 
     items.push(r); 
    } 
    return items; 
}; 

Answer 1

var newitems=[]; 
//loop through each item in the original 
for(var i =0; i<items.length; i++) 
{ 
    newitems[i] = []; 
    //loop over the properties in each element and push it to an array 
    for(var prop in items[i]){ 
    newitems.push(items[i][prop]); 
    } 
} 

或者：

var newitems = items.map(function(elem){ 
    var item = []; 
    for(var prop in elem){ 
    item.push(elem[prop]); 
    } 
    return item; 
})
