Question

我有一个结构对象数组来自迭代数组对象的服务器响应，如样本

array[1] ={
    "ID": "123",
    "Name": "John",
    "Age": "15"     
}
array[2] ={
    "ID": "456",
    "Name": "Sue",
    "Age": "18"     
}
array[n] ={

}

但是现在我想追加数组值，如果条件年龄低于18，则在以下结构中作为上述数组的迭代值预期产出：

{
    "Stud": [{
        "ID": "123",
        "Name": "John",
        "Age": "15"
    }, {
        "ID": "456",
        "Name": "Sue",
        "Age": "18"
    },{n........
  }]
}

Answer 1

var output = { "Stud" : [] };
for (var i = array.length - 1; i >= 0; i--) {
    if (array[i].Age < 18) {
        output.Stud.push(array[i]);
    }
}
console.log(output);

Answer 2

简单地

var output = { "Stud" : array }; //existing 'array'

Answer 3

您可以使用function code() { var leer = document.getElementById('1').value, array = []; //debugger; for (var i = 0; i < leer.length; i++) { array[i] = leer[i].charCodeAt(0); } document.getElementById('2').innerHTML = 'Chale, chale ' + array.join(''); } function decode() { var leer = document.getElementById('1').value, array = []; //debugger; for (var i = 0, char; char = leer[i]; i++) { array[i] = String.fromCharCode(leer[i].charCodeAt(0)); } document.getElementById('2').innerHTML = 'Chale, chale ' + array.join(''); }选择年龄小于或等于18的对象。

Answer 4

简单地迭代并检查年龄是否< 18或不。如果是这样推动到另一个阵列。

    var array = [];
    var array_below_18 = [];
    array[0] ={
        "ID": "123",
        "Name": "John",
        "Age": "15"     
    }
    array[1] ={
        "ID": "456",
        "Name": "Sue",
        "Age": "18"     
    }

    array[1] ={
        "ID": "456",
        "Name": "Sue",
        "Age": "14"     
    }

    for(i=0;i<array.length;++i){
       if(parseInt(array[i].Age)<18){
          array_below_18.push(array[i]);
       }
    }

    var final_object = {
        "Stud" : array_below_18
    }

    console.log(final_object);

将多个对象附加到单个数组中
