Question

动态地我得到array。

例如，我们可以考虑以下array。

var sampleArray=[
        "logo",
        "Details",
        "titles"
    ];

但我想要这样的东西。

jsonObj={
"poistion1":"logo",
"poistion2":"Details",
"poistion3":"titles"
}

Answer 1

您可以迭代数组并创建对象，如下所示

<fieldType name="string_ci" class="solr.TextField" sortMissingLast="true"    omitNorms="true" positionIncrementGap="100">
  <analyzer type="index">
    <tokenizer class="solr.KeywordTokenizerFactory"/>
      <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
  <analyzer type="query">
    <tokenizer class="solr.KeywordTokenizerFactory"/>
    <filter class="solr.LowerCaseFilterFactory"/>
  </analyzer>
</fieldType>

Answer 2

您可以创建一个空对象，然后循环（Array.forEach()）数组并指定值

var sampleArray = [
  "logo",
  "Details",
  "titles"
];
var obj = {};
sampleArray.forEach(function(value, idx) {
  obj['position' + (idx + 1)] = value
});

snippet.log(JSON.stringify(obj))

<script src="http://tjcrowder.github.io/simple-snippets-console/snippet.js"></script>
<!-- Provides the `snippet` object, see http://meta.stackexchange.com/a/242144/134069 -->

Answer 4

var arr=[
        "logo",
        "Details",
        "titles"
    ];
var result = {};
  for (var i = 0; i < arr.length; ++i){
      result["position" + (i+1)] = arr[i];
 }

Answer 5

试试这个

var obj = {};
var sampleArray=[
        "logo",
        "Details",
        "titles"
    ];

for(var index in  sampleArray) {
     obj['pos' + index] = sampleArray[index];
   }

Answer 6

您可以使用JSON对象：

var yourObject = [123, "Hello World", {name: "Frankie", age: 15}];
var yourString = JSON.stringify(yourObject); // "[123,"Hello World",{"name":"Frankie","age":15}]"

JSON对象还具有JSON到对象功能：

var anotherObject = JSON.parse(yourString);

如何将Array转换为json对象？
