Jquery get link values from data object

问题

I can't for the life of me figure out how to access the values inside this object. Any help would be much apreciated

End goal, once I can access the link, i'll iterate each and append and img tag to the dom after the images-header element.

JS to consume json

$("#stack_name").focusout(function() {
  var name = $(this).val();
  // alert(name);

  $.getJSON('/images.json?name='+ name, function(data) {
    console.log("DATA: ", data);
    // $('<p>Test</p>').appendTo('.images-header');
  });
});

Console Log outputs:

DATA:  
Object {data: Object}
data: Object
images: Array[4]
0: "http://upload.wikimedia.org/wikipedia/commons/thumb/6/6e/Connecticut_in_United_States.svg/270px-Connecticut_in_United_States.svg.png"

}
}

回答1:

You can access images array like this, you have have to parse json string using $.parseJSON

img1 = jsonObj.data.Images[0];

Live Demo

You can iterate through array using for loop

for(i=0; i < jsonObj.data.images.length; i++)
{
    alert(jsonObj.data.images[i]);
}

Try

Fiddle Demo

$("#stack_name").focusout(function() 
{
  var name = $(this).val();

  $.getJSON('/images.json?name='+ name, function(data) 
  {
    var images = data.data.images;
    var $header = $('.images-header');

    for(var index in images )
    {
      var $image = $('<img><img/>'); 
      var link = images[index];

      $image.attr("src", link);
      $header.append($image);
    }

  });
});
