提问by Shrinivas Pai
Dynamically I am getting an array.
我动态地得到一个array.
For example we can consider this following array.
例如，我们可以考虑如下array。
var sampleArray=[
"logo",
"Details",
"titles"
];
But I want it something like this.
但我想要这样的东西。
jsonObj={
"poistion1":"logo",
"poistion2":"Details",
"poistion3":"titles"
}

You can iterate on array and create object like following
您可以迭代数组并创建如下对象
var jsonObj = {};
for (var i = 0 ; i < sampleArray.length; i++) {
jsonObj["position" + (i+1)] = sampleArray[i];
}

Like this
像这样
var jsonObj = {};
var sampleArray = [
"logo",
"Details",
"titles"
];
for (var i = 0, len = sampleArray.length; i < len; i++) {
jsonObj['position' + (i + 1)] = sampleArray[i];
}
console.log(jsonObj);回答by Arun P Johny
You can create an empty object, then loop over(Array.forEach()) the array and assign the value
您可以创建一个空对象，然后循环遍历（Array.forEach()）数组并分配值
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>

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

try this
试试这个
var obj = {};
var sampleArray=[
"logo",
"Details",
"titles"
];
for(var index in sampleArray) {
obj['pos' + index] = sampleArray[index];
}

You can use the JSON Object:
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}]"
the JSON object has also JSON-to-Object functionality:
JSON 对象还具有 JSON-to-Object 功能：
var anotherObject = JSON.parse(yourString);
var anotherObject = JSON.parse(yourString);
