已使用$.each

$.each(response.post.custom_fields, function( index, value ) {
             console.log( index + ": " + value );
});

$(document).ready(function(){
			var response={
      "status": "ok",
      "post": {
        "id": 25,
        "type": "post",
        "slug": "price-list",
        "url": "http://example.com/2016/02/10/post-title/",
        "status": "publish",
        "title": "title",
        "title_plain": "title",
        "content": "",
        "excerpt": "",
        "date": "2016-02-10 12:23:40",
        "modified": "2016-06-01 06:27:39",
        "categories": [],
        "tags": [],
        "author": {
          "id": 1,
          "slug": "slug",
          "name": "name",
          "first_name": "first name",
          "last_name": "last name",
          "nickname": "nickname",
          "url": "",
          "description": "descp"
        },
        "comments": [],
        "attachments": [],
        "comment_count": 0,
        "comment_status": "open",
        "custom_fields": {
          "Regular 95": [
            "34200:1"
          ],
          "Super 98": [
            "34900:0"
          ],
          "Gasoil": [
            "26100:-1"
          ],
          "Diesel": [

          ],
          "Kerosene": [
            "20100:-1"
          ],
          "Fuel / Ton": [
            "773.30:0"
          ]
        }
      },
      "previous_url": "http://example.com/2016/02/10/post-title/",
      "next_url": "http://example.com/2016/02/10/post-title/"
    };
		
		$.each(response.post.custom_fields, function( index, value ) {

Answer 2

从w3c doc，不同的方法来访问JavaScript属性：

objectName.property          // person.age
objectName["property"]       // person["age"]
objectName[expression]       // x = "age"; person[x]

表达式必须评估为属性名称。

您可以使用嵌套对象链接

objectName.internalObject.property
