从jQuery数组中的数组中获取特定元素

Question

I am having some trouble with getting what I want out of jQuery. I have an ajax call that returns and array of arrays.

my jQuery looks something like this...

$.each(search_results, function()
{
  $.each(this, function(results)
  {
    var first_name = '';
    var last_name = '';
    $.each(this, function(index, value)
    {
      if(index == 3 )
      {
        last_name = value;
      }

      if(index == 5)
      {
        first_name = value;
        var contact_name = first_name + " " + last_name;
        var result_item = '<li class="list-group-item">' + contact_name + '</li>';
          $(id).append(result_item);
      }
    });
  });
});

This works and is all well and good, but I'm returning hundreds of records. Looping through each element in the array to pickout two to five elements seems like WAY too much work.

Is there a way to do something like this...

  $.each(search_results, function()
{
  $.each(this, function(results)
  {
    $.each(this, function(result)
    {
       var first_name = result[5];
       var last_name = result[3];
        var contact_name = first_name + " " + last_name;
        var result_item = '<li class="list-group-item">' + contact_name + '</li>';
          $(id).append(result_item);
      }
    });
  });
});

I found a similar question here , but the answer seems odd to me. There has to be a way....

I hope this helps more

Array / JSON Structure:

Object { search_results: […] }
search_results : Array [ […], […], […], … ]
[0..99]
0 : Array [ "all", "stuff", "I want", … ]

From what I understood from your question, you have an array similar to:

 var search_results = [
                         [
                            [1.0, 1.1, 1.2, 1.3, 1.4, 1.5], 
                            [2.0, 2.1, 2.2, 2.3, 2.4, 2.5]
                         ]
                      ];

And you want to access elements 1.3, 1.5, 2.3, 2.5....

Following code will access those elements.

$.each(search_results, function(l1_index, l1_result)
{
   $.each(this, function(l2_index, l2_result)
   {
     if(l2_result.length > 5)
     {
         var last_name = l2_result[3];
         var first_name = l2_result[5];
         var contact_name = first_name + " " + last_name;
         var result_item = '<li class="list-group-item">' + contact_name + '</li>';
         $(id).append(result_item);
     }
  });
});

PS: If you can post your array structure everyone can better understand your question.
