我必须再次用更多细节重新发布这个问题：

我有一个 JSON 树array。

JSON 树的结构如下所示：

{
"app": {

    "categories": {

        "cat_222": {
            "id": "555",
            "deals": [{
                "id": "73",
                "retailer": "JeansWest"

            }, {
                "id": "8630",
                "retailer": "Adidas"

            }, {
                "id": "11912",
                "retailer": "Adidas"

            }]
        },

        "cat_342": {
            "id": "232",
            "deals": [{
                "id": "5698",
                "retailer": "KFC"
            }, {
                "id": "5701",
                "retailer": "KFC"
            }, {
                "id": "5699",
                "retailer": "MC"

            }]
        }
    }
  }
}

现在，我想过滤这个 JSON 树var pattern="KF"，

返回所有包含retailer名称KF的内容及其 id。

使用Array.filter或者_.filter如果你需要支持 IE < 9

Well, you can use _.filter:

var filteredArray = _.filter(arrayOfStrings, function(str) { 
  return str.indexOf(data) !== -1; });

... or jQuery.grep:

var filteredArray = $.grep(arrayOfStrings, function(str) { 
  return str.indexOf(data) !== -1; });

As you see, the approaches are quite similar - and, in fact, both use Array.filter, if it's available in the host environment.

Also note that the original array is not affected here. If you want otherwise, just assign the result of filtering to the same variable (i.e., arrayOfStrings in this example).
