insert_top

Inserts HTML before the contents of an HTML element.

Adds a template or a literal HTML text before the existing content.

Example:

<div id="mydiv"><p>Bye Bye.</p></div>
{% button text="hello" action={insert_top target="mydiv" text="<p>Hello World!</p>"} %}

After the button is clicked, the contents of the div will be “<p>Hello World!</p><p>Bye Bye.</p>”.

Another example, now rendering a template:

<ul id="mylist"><li>Some item</li></li>
{% button text="hello" action={insert_top target="mylist" template="_list_item.tpl" id=42} %}

This insert the output of the template “_list_item.tpl” above the existing <li/>.  All arguments to the update action are also arguments to the template.

See also the actions update and insert_bottom.
