将一个数组的三个实例推送到另一个单个数组-javaScript

我正在研究JavaScript函数，我正在为之奋斗

我有两个数组

数组1保存单个记录，数组2保存示例3记录。我想将数组1中数组2的三条记录推送到数组1记录的同一索引中

这就是我想要实现的，以便以后可以转换为JSON 示例代码

var selectedComponentList=[]；
var selectElementList=[]；
var QualificationElementsEnetsandComponentList=[]；
selectElementList={
元素索引：1，
ElementMarkingSchemeTitle:“markingScheme1”，
元素可用标记：100，
元素密码：50，
元素标记：60，
元素区分标记：70
};
selectedComponentList={
组件索引：1，
组件标记：80
};
selectedComponentList={
组件索引：23，
成分分数：50
};
selectedComponentList={
组件索引：3，
成分分数：10
};
$（文档）.ready（函数（）{
}); //结束JQuery

实际上，您必须使用Array.prototype.splice方法

z = [1,2,3];
z.splice(1,0,6,7,8,9);
console.log(z); // [1, 6, 7, 8, 9, 2, 3] 

试试下面的方法

var QualificationElemenetsAndComponentsList = [];

var selectElementList = {//this is a javascript object
    ElementIndex: 1,
    ElementMarkingSchemeTitle: "markingScheme1",
    ElementAvailableMark: 100,
    ElementPassMark: 50,
    ElementMeritMark: 60,
    ElementDistinctionMark: 70
};
selectedComponentList = [];

selectedComponentList[selectedComponentList.length] = {
    componentIndex: 1,
    componentMark: 80
};

selectedComponentList[selectedComponentList.length] = {
    componentIndex: 23,
    componentMark: 50
};

selectedComponentList[selectedComponentList.length] = {
    componentIndex: 3,
    componentMark: 10
};

selectElementList.Component = selectedComponentList; //Here's how you assign the array to the object property

QualificationElemenetsAndComponentsList[QualificationElemenetsAndComponentsList.length] = selectElementList;

我已经设法解决了，请告诉我，如果它是正确的

构建selectElementList 生成所选组件列表 将组件（数组2）绑定到元素（数组1） 将带有固定组件的array1元素推送到最终阵列 空阵列1和阵列2 然后对每个元素重复该循环

下面的代码生成JSON输出

 var myElementList = "";

 myElementList = JSON.stringify({ QualificationElemenetsAndComponentsList: QualificationElemenetsAndComponentsList });

 document.write("JSPN >>>>   " + myElementList);

JSON输出

您的JSON示例是错误的。使用

selectedComponentList={}

只需重新分配一个变量。如果要将某些内容推送到数组，请使用

selectedComponentList.push（{}，{}，{}）

。如果要将整个数组推送到另一个数组，请使用

selectedComponentList.push.apply（selectedComponentList，另一个数组）。
var QualificationElemenetsAndComponentsList = [];

var selectElementList = {//this is a javascript object
    ElementIndex: 1,
    ElementMarkingSchemeTitle: "markingScheme1",
    ElementAvailableMark: 100,
    ElementPassMark: 50,
    ElementMeritMark: 60,
    ElementDistinctionMark: 70
};
selectedComponentList = [];

selectedComponentList[selectedComponentList.length] = {
    componentIndex: 1,
    componentMark: 80
};

selectedComponentList[selectedComponentList.length] = {
    componentIndex: 23,
    componentMark: 50
};

selectedComponentList[selectedComponentList.length] = {
    componentIndex: 3,
    componentMark: 10
};

selectElementList.Component = selectedComponentList; //Here's how you assign the array to the object property

QualificationElemenetsAndComponentsList[QualificationElemenetsAndComponentsList.length] = selectElementList;

  selectElementList.push({ ElementIndex: E_RecordId, ElementMarkingSchemeTitle: E_MarkingSchemeTitle, ElementAvailableMark: E_AvailableMark, ElementPassMark: E_PassMark, ElementMeritMark: E_MeritMark, ElementDistinctionMark: E_DistinctionMark });

   selectedComponentList.push({ componentIndex: recordId, componentMark: ComponentSchemeMark });

selectElementList.push({ Components: selectedComponentList });

QualificationElemenetsAndComponentsList.push({ Element: selectElementList });

selectElementList = [];
selectedComponentList = [];

 var myElementList = "";

 myElementList = JSON.stringify({ QualificationElemenetsAndComponentsList: QualificationElemenetsAndComponentsList });

 document.write("JSPN >>>>   " + myElementList);
