Javascript 如何对JSON对象进行计数，并在计数的基础上获得相同的输出

如何对JSON对象进行计数，并在计数的基础上获得相同的输出

    var obj = 
   [
    {"id":"0","name":"Mike Johnson","group":1},
    {"id":"1","name":"Bob Smith","group":2},
    {"id":"2","name":"Richard Thomas","group":3},
    {"id":"3","name":"Betty White","group":16},
    {"id":"4","name":"Tim Thompson","group":3},
    {"id":"5","name":"Carl Lewis","group":16},
    {"id":"6","name":"Kathy Towers","group":3},
    {"id":"7","name":"Billy Bob","group":1},
    {"id":"8","name":"Sally Bailey","group":1}
    ];

首先我想在计数的基础上再计数。我想要和输入一样的输出。 计数：

var count = 0;
function getCount() {

for (var i = 0; i < obj.length; i++) {

        count++;

}
return count;
}

var计数=0；
函数getCount（）{
对于（变量i=0；i

对于输出：-

function showDetails()   this is not giving the proper output
{ 

   for(var j=0; j< count; j++){ 
   obj.push([{j}]);    
   }                   
alert(obj.name);        
}                      
alert(showDetails());   
And I want an output like:- 

     var obj = 
   [
    {"id":"0","name":"Mike Johnson","group":1},
    {"id":"1","name":"Bob Smith","group":2},
    {"id":"2","name":"Richard Thomas","group":3},
    {"id":"3","name":"Betty White","group":16},
    {"id":"4","name":"Tim Thompson","group":3},
    {"id":"5","name":"Carl Lewis","group":16},
    {"id":"6","name":"Kathy Towers","group":3},
    {"id":"7","name":"Billy Bob","group":1},
    {"id":"8","name":"Sally Bailey","group":1}
    ];

函数showDetails（），这没有提供正确的输出
{ 
对于（var j=0；j

有人能帮我吗

var str=“一月、二月、三月、四月、五月、六月、七月、八月、九月、十月”；
var arr=str.split（'，'）.map（函数（v）{
返回{name:v}；
});
控制台日志（arr）
obj
将是所需的输出
您可以这样做：

    var obj = 
   [
    {"id":"0","name":"Mike Johnson","group":1},
    {"id":"1","name":"Bob Smith","group":2},
    {"id":"2","name":"Richard Thomas","group":3},
    {"id":"3","name":"Betty White","group":16},
    {"id":"4","name":"Tim Thompson","group":3},
    {"id":"5","name":"Carl Lewis","group":16},
    {"id":"6","name":"Kathy Towers","group":3},
    {"id":"7","name":"Billy Bob","group":1},
    {"id":"8","name":"Sally Bailey","group":1}
    ];

var str = "January,February,March,April,May,June,July,August,September,October";
var months = str.split(",");
var result = [];


for (i in months)
{
   var month = {};
   month.name = months[i];
   //you can do more things else here, for example:
   //month.monthOfYear = (i+1);
   //month.numberOfDay = 123123123;
   result.push(month);
}

var array = string.split(",");
var finalArray = [];

array.forEach(function(item){

   var obj = {
        name: item
   }

   finalArray.push(obj);

});

console.log(finalArray);

对于更重的ES2015版本。常量、箭头函数和隐式返回语句

const str = 'January,February,March,April,May,June,July,August,September,October'
const result = str.split(',').map(name => ({name}))
console.log(result)


使用
var数组=string.split（'，'）
var数组=新数组（字符串）；正如我向您展示的那样，它没有给出输出。这似乎使用了目前并非所有浏览器都支持的js语法。是的。这是ECMA6箭头函数表达式
。在不久的将来，希望所有的浏览器都能提供良好的ECMA5支持solution@Arvind欢迎，请接受任何解决您问题的答案）好的，兄弟，我还问一个问题，您能提供解决方案吗。@ArvindChaudhary是的，如果可能的话，请现在问。。我马上就走
