jQuery从数据对象获取链接值 [英] Jquery get link values from data object

问题描述

我一辈子都无法弄清楚如何访问该对象内的值.任何帮助将不胜感激

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

最终目标，一旦我可以访问链接，我将对其进行迭代，并将images-header元素后的img和img标签附加到dom.

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使用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');
  });
});

控制台日志输出:

DATA:  
Object {data: Object}
data: Object
images: Array[4]

}
}

推荐答案

您可以像这样访问图像数组，必须使用

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

img1 = jsonObj.data.Images[0];

实时演示

Live Demo

您可以使用for循环遍历数组

You can iterate through array using for loop

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