HTMLTableElement.createCaption() - Web APIs 编辑

The HTMLTableElement.createCaption() method returns the <caption> element associated with a given <table>. If no <caption> element exists on the table, this method creates it, and then returns it.

Note: If no caption exists, createCaption() inserts a new caption directly into the table. The caption does not need to be added separately as would be the case if Document.createElement() had been used to create the new <caption> element.

Syntax

HTMLTableElement = table.createCaption();

Return value

HTMLTableCaptionElement

Example

</table>

JavaScript

let table = document.querySelector('table');
let caption = table.createCaption();
caption.textContent = 'This caption was created by JavaScript!';
