javascript - 构建一个 JS 函数来动态创建 HTML 元素并将它们相互嵌套

Question

我创建了下面的函数来动态创建 HTML 元素并将它们附加到我想要的任何位置。控制台在运行时不会记录任何错误，但第二个元素( <p> )不写入文档。

我认为错误与“createdDiv”变量有关，但我无法找出问题所在。

如有任何帮助，我们将不胜感激!

//Array of elements to be created

var createdElements = [
    [ 'div', 'Class0', 'ID0'],
    ['p', 'Class1', 'ID1']      
];


//function to create and append elements to document

function createHTML( typeOfCreatedElement ,createdElementClass, createdElementId, locationForCreatedElement ){
    var createdElement = document.createElement( typeOfCreatedElement );
    createdElement.className = createdElementClass;
    createdElement.id = createdElementId;

    locationForCreatedElement['appendChild']( createdElement );

    return createdElement;
}


//run function 2x; 
//createdDiv successfully writes to the document, but createdParagraph disappears into a black hole...

var createdDiv = createHTML( createdElements[0][0], createdElements[0][1], createdElements[0][2], document.body );
var createdParagraph = createHTML( createdElements[1][0], createdElements[1][1], createdElements[1][2], createdDiv );

你能试试这个更新的createHTML method()吗

function createHTML( typeOfCreatedElement ,createdElementClass, createdElementId, locationForCreatedElement ){
    var createdElement = document.createElement( typeOfCreatedElement );
    createdElement.className = createdElementClass;
    createdElement.id = createdElementId;
    createdElement.innerHTML = "this is a sample text for element type " + typeOfCreatedElement;

    locationForCreatedElement.appendChild( createdElement ); //line that I have changed.

    return createdElement;
} 

appendChild是方法，不是属性。
