The "html" binding
html binding causes the associated DOM element to display the HTML specified by your parameter.
Typically this is useful when values in your view model are actually strings of HTML markup that you want to render. If you know your view model value is plain text, use the more efficient text binding instead.
KO clears the previous content and then sets the element’s content to your parameter value using jQuery’s
htmlfunction or by parsing the string into HTML nodes and appending each node as a child of the element, if jQuery is not available.
If this parameter is an observable value, the binding will update the element’s content whenever the value changes. If the parameter isn’t observable, it will only set the element’s content once and will not update it again later.
If you supply something other than a number or a string (e.g., you pass an object or an array), the
innerHTMLwill be equivalent to
Note: About HTML encoding
Since this binding sets your element’s content using
innerHTML, you should be careful not to use it with untrusted model values, because that might open the possibility of a script injection attack. If you cannot guarantee that the content is safe to display (for example, if it is based on a different user’s input that was stored in your database), then you can use the text binding, which will set the element’s text value instead.
None, other than the core Knockout library.
