[英]Why am I not getting a table with the following code?
let myLibrary = [
["Title", "Author", "Pages", "Have you read the book"]
["Harry Potter", "JK Rowling", "366", No],
["My Test Book", "Myself", "50", Yes]
];
function render(){
let table = document.getElementById('table');
for(let book in myLibrary){
let row = table.insertRow();
for(let bookInfo in book){
let cell = row.insertCell()
cell.innerHTML = bookInfo;
}
}
}
我期待我會得到一個包含以下代碼的表格。 但我剛開始 0 作為輸出。 任何人都可以找到解決方案嗎?
您可以使用forEach
來迭代數組:
function render() {
let table = document.getElementById("table");
myLibrary.forEach(function (r) {
let row = table.insertRow();
r.forEach(function (c) {
let cell = row.insertCell();
cell.innerHTML = c;
});
});
}
