Question

我有一个像这样的JSON：

    var parse = [
   {
      "variation_id":"34",
      "attributes":{
         "attribute_pa_rozmiar":"m"
      },
      "image_src":"http://localhost/Fraise-WP/wp-content/uploads/2013/06/Jellyfish-300x300.jpg",
      "image_link":"http://localhost/Fraise-WP/wp-content/uploads/2013/06/Jellyfish.jpg",
      "image_title":"Jellyfish",
      "price_html":"",
      "availability_html":"<p class=\"stock \">10 w magazynie</p>",
      "sku":"",
      "weight":"4 kg",
      "dimensions":"",
      "min_qty":1,
      "max_qty":"10",
      "backorders_allowed":false,
      "is_in_stock":true,
      "is_downloadable":false,
      "is_virtual":false,
      "is_sold_individually":"no"
   },
   {
      "variation_id":"33",
      "attributes":{
         "attribute_pa_rozmiar":"s"
      },
      "image_src":"http://localhost/Fraise-WP/wp-content/uploads/2013/06/Desert-300x300.jpg",
      "image_link":"http://localhost/Fraise-WP/wp-content/uploads/2013/06/Desert.jpg",
      "image_title":"Desert",
      "price_html":"",
      "availability_html":"<p class=\"stock \">5 w magazynie</p>",
      "sku":"",
      "weight":"4 kg",
      "dimensions":"",
      "min_qty":1,
      "max_qty":"5",
      "backorders_allowed":false,
      "is_in_stock":true,
      "is_downloadable":false,
      "is_virtual":false,
      "is_sold_individually":"no"
   }
][
   {
      "variation_id":"34",
      "attributes":{
         "attribute_pa_rozmiar":"m"
      },
      "image_src":"http://localhost/Fraise-WP/wp-content/uploads/2013/06/Jellyfish-300x300.jpg",
      "image_link":"http://localhost/Fraise-WP/wp-content/uploads/2013/06/Jellyfish.jpg",
      "image_title":"Jellyfish",
      "price_html":"",
      "availability_html":"<p class=\"stock \">10 w magazynie</p>",
      "sku":"",
      "weight":"4 kg",
      "dimensions":"",
      "min_qty":1,
      "max_qty":"10",
      "backorders_allowed":false,
      "is_in_stock":true,
      "is_downloadable":false,
      "is_virtual":false,
      "is_sold_individually":"no"
   },
   {
      "variation_id":"33",
      "attributes":{
         "attribute_pa_rozmiar":"s"
      },
      "image_src":"http://localhost/Fraise-WP/wp-content/uploads/2013/06/Desert-300x300.jpg",
      "image_link":"http://localhost/Fraise-WP/wp-content/uploads/2013/06/Desert.jpg",
      "image_title":"Desert",
      "price_html":"",
      "availability_html":"<p class=\"stock \">5 w magazynie</p>",
      "sku":"",
      "weight":"4 kg",
      "dimensions":"",
      "min_qty":1,
      "max_qty":"5",
      "backorders_allowed":false,
      "is_in_stock":true,
      "is_downloadable":false,
      "is_virtual":false,
      "is_sold_individually":"no"
   }
]

我需要的是在attributes内运行搜索，查找此对象是否具有，例如。 attribute_pa_rozmiar=m并获得相应的image_src。很抱歉这样一个臃肿的JSON，但这是我能把它拿出来的唯一方法。

Answer 1

我尝试根据找到的exaples运行$ .each和$ .map函数，但都没有。

请尝试$.grep：

var filtered = $.grep(parse, function(item) {
    return item.attributes.attribute_pa_rozmiar == "m";
});
var images = $.map(filtered, function(item) {
    return item.image_src;
});

Answer 2

试试这个..它使用$ .each并且工作正常

      $.each(parse, function(i, item) {
          $.each(item, function(j, innerItem){
           // perform search on innerItem.a or innerItem.b
          });
      });

根据您的新更新，您的JSON首先无效。你有额外的] [在可变数据的中间。我创建了另一个JSFiddle来解决你的问题。参见工作演示：
