<template>

Summary

The HTML template element <template> is a mechanism for holding client-side content that is not to be rendered when a page is loaded but may subsequently be instantiated during runtime using JavaScript. Think of a template as a content fragment that is being stored for subsequent use in the document. The parser does process the content of the <template> element during the page load to ensure that it is valid, however.

Attributes

This element includes the global attributes.

There is also a content attribute, which is read-only. It provides access to the contents of the template. The existence of the content attribute is often used as a way of determining if a particular browser supports the <template> element.

Examples

First we start with the HTML portion of the example.

<table id="producttable">
 <thead>
  <tr>
   <td>UPC_Code</td>
   <td>Product_Name</td>
  </tr>
 </thead>
 <tbody>
  <!-- existing data could optionally be included here -->
 </tbody>
</table>

<template id="productrow">
  <tr>
  <td class="record"></td>
  <td></td>
</template> 

Then we see the JavaScript portion of the example, which can be used to instantiate the HTML.

// Test to see if the browser supports the HTML template element by checking
// for the presence of the template element's content attribute.
if ('content' in document.createElement('template')) {

  // Instantiate the table with the existing HTML tbody and the row with the template
  var t = document.querySelector('#productrow'),
  td = t.content.querySelectorAll("td");
  td[0].textContent = "1235646565";
  td[1].textContent = "Stuff";

  // Clone the new row and insert it into the table
  var tb = document.getElementsByTagName("tbody");
  var clone = document.importNode(t.content, true);
  tb[0].appendChild(clone);
  
  // Create a new row
  td[0].textContent = "0384928528";
  td[1].textContent = "Acme Kidney Beans";

  // Clone the new row and insert it into the table
  var clone2 = document.importNode(t.content, true);
  tb[0].appendChild(clone2);

} else {
  // Find another way to add the rows to the table because 
  // the HTML template element is not supported.
}

The result is the original HTML table, with two new rows appended to it via JavaScript.
