The dialogmodal target attributes

+ +

Buttons may have the following content attributes:

+ + + +

If specified, the dialogmodaltarget attribute value must + be the ID of a dialog element + in the same tree as the button with the + dialogmodaltarget attribute.

+ +
+

The following shows how the dialogmodaltarget attribute + can be used to show and close a dialog:

+ + 
<button dialogmodaltarget="foo">
+  Show a dialog (modal)
+</button>
+
+<dialog id="foo">
+  This is a dialog!
+  <button dialogmodaltarget="foo">Close</button>
+</article>
+
+ + DOM interface: + 
interface mixin DialogInvokerElement {
+  [CEReactions] attribute Element? dialogModalTargetElement;
+};
+ +

The dialogModalTargetElement IDL attribute must + reflect the dialogmodaltarget attribute.

+ +

To run the dialog modal target attribute activation behavior given a Node + node:

+ +
    +

  1. Let dialog be node's dialog modal target element.

    2. + +

  2. If dialog is null, then return.

    3. + +

  3. If the open attribute is set on node + then: + +

      +

    1. Run close()

      on node
      2. +

    2. Otherwise, run showModal() on node

      3. +
    + +
    4. +
+ +

To get the dialog modal target element given a Node node, perform + the following steps. They return an HTML element or null.

+ +
    +

  1. If node is not a button, then return + null.

    2. + +

  2. If node is disabled, then return + null.

    3. + +

  3. If node has a form owner and node is a submit button, then return null.

    4. + +

  4. Let dialogElement be node's dialogmodaltarget-associated element.

    5. + +

  5. If dialogElement is null, then return null.

    6. + +

  6. If dialogElement is not a dialog element, then return null.

    7. + +

  7. Return dialogElement.
