Example
Use the content of a template for each item in an array:
<template>
<div class="myClass">I like: </div>
</template>
<script>
let myArr = ["Audi", "BMW", "Ford", "Honda", "Jaguar",
"Nissan"];
function showContent() {
let temp, item, a,
i;
// Get the template element:
temp =
document.getElementsByTagName("template")[0];
// Get the DIV element from the template:
item =
temp.content.querySelector("div");
// For each item in the array:
for (i = 0; i < myArr.length; i++) {
// Create a new
node, based on the template:
a = document.importNode(item,
true);
// Add data from the
array:
a.textContent += myArr[i];
// Append the new node wherever you like:
document.body.appendChild(a);
}
}
