Question

我可以使用AngularJS forEach从ES（v1.5）迭代这个JSON响应吗？

{response:[property: value,property: value, hits:{property: value, property: value}, hits: [{property:value,property:value, {property:value}}], hits:[{property:value,property:value, {property:value}}]]}

正如你所看到的，response []有2个命中数组，两个命中数组都有很多对象。尝试使用angular.forEach迭代它们......但没有太多运气

我是否需要打破每个命中数组并通过自己的forEach运行它？

var multi_match_results = es_return.responses[0].hits.hits;
angular.forEach(multi_match_results), function(value, key) {
...
}


var mlt_results = es_return.responses[1].hits.hits;
angular.forEach(mlt_results), function(value, key) {
...
}

OR

有没有办法用嵌套的forEach迭代这些？如果是这样，一些示例代码就会很棒！

更新

以下是从ES

返回的实际数据的一小部分示例

    {
   "responses": [
      {
         "took": 38,
         "timed_out": false,
         "_shards": {
            "total": 1,
            "successful": 1,
            "failed": 0
         },
         "hits": {
            "total": 6,
            "max_score": 2.8937743,
            "hits": [
               {
                  "_index": "query-index1",
                  "_type": "autocomplete",
                  "_id": "AVhO-9ifp_gdq4wcr69k",
                  "_score": 2.8937743,
                  "_source": {
                     "suggestions": "term term"
                  }
               },
               {
                  "_index": "query-index1",
                  "_type": "autocomplete",
                  "_id": "AVhO-9ifp_gdq4wcr69l",
                  "_score": 2.8937743,
                  "_source": {
                     "suggestions": "term1 term1"
                  }
               }
            ]
         }
      },
      {
         "took": 51,
         "timed_out": false,
         "_shards": {
            "total": 1,
            "successful": 1,
            "failed": 0
         },
         "hits": {
            "total": 317,
            "max_score": 3.055048,
            "hits": [
               {...

因此，您可以在返回对象中看到响应数组，其中包含2个单独的命中数组，这些命中数组包含保存2个查询数据的对象。

我的搜索结果（）返回结果

return searchService.search(vm.searchTerms, vm.currentPage).then(function(es_return) {
    var results = es_return.responses;
    var totalItems = es_return.responses[0].hits.total;
    var totalTime = es_return.responses[0].took;
    var numPages = Math.ceil(es_return.responses[0].hits.total / vm.itemsPerPage);
    vm.results.pagination = [];
    for (var i = 0; i < results.length; i++) {
      console.log(results);
      for (var j = 0; j < results.length; j++) {
        console.log(results);
      vm.results.totalItems = totalItems;
      console.log(vm.results.totalItems);
      vm.results.queryTime = totalTime;
      vm.results.pagination = searchService.formatResults(es_return.responses[0].hits.hits);//load first 100 results
      vm.results.documents = vm.results.pagination.slice(vm.currentPage, vm.itemsPerPage);
      console.log(vm.results.documents);
      vm.results.mlt = es_return.responses[1].hits.hits;
      }
    }

您看到的2 for循环不适合该作业。有什么建议吗？

看起来你拥有的JSON不是有效的JSON，因为你有重复的密钥。您可能想重新考虑生成json值的方式。

这是一篇类似的帖子：

当您有重复键时，迭代会发生什么这里。

var responseObj = {
  response: [property: value, property: value, hits: {
      property: value,
      property: value
    },
    hits: [{
      property: value,
      property: value,
      {
        property: value
      }
    }],
    hits: [{
      property: value,
      property: value,
      {
        property: value
      }
    }]
  ]
};
