Answer 2

function getAttributesByName(arr,name){ 
    for(var i=0,l=arr.length;i<l;i++) 
     if(arr[i].Name === name) 
      return arr[i]; 
    return null;    
} 

よりjqueryのアプローチ：

function getAttributesByName(arr,name){ 
    var result = null; 
    $.each(arr,function(){ 
     if(this.Name === name) 
      result = this; 
    }); 
    return result; 
} 

Answer 3

ここにあります：

var a = data.Attributes; 
for(var i in a) { 
    if(a.hasOwnProperty(i) && a[i].Name == 'bathrooms') 
     return a[i].Value; 
}
