# --description--
|
|
|
|
Du kannst auch die Nicht-CSS-Eigenschaften von HTML-Elementen mit jQuery ändern. Du kannst zum Beispiel Buttons deaktivieren.
|
|
|
|
Wenn du einen Button deaktivierst, wird er ausgegraut und kann nicht mehr angeklickt werden.
|
|
|
|
jQuery hat eine Funktion namens `.prop()`, mit der du die Eigenschaften von Elementen anpassen kannst.
|
|
|
|
So kannst du alle Buttons deaktivieren:
|
|
|
|
```js
|
|
$("button").prop("disabled", true);
|
|
```
|
|
|
|
Deaktiviere nur den Button `target1`.
|
|
|
|
# --hints--
|
|
|
|
Dein Button `target1` sollte deaktiviert sein.
|
|
|
|
```js
|
|
assert(
|
|
$('#target1') &&
|
|
$('#target1').prop('disabled') &&
|
|
code.match(/["']disabled["'],( true|true)/g)
|
|
);
|
|
```
|
|
|
|
Alle anderen Buttons sollten nicht deaktiviert sein.
|
|
|
|
```js
|
|
assert($('#target2') && !$('#target2').prop('disabled'));
|
|
```
|
|
|
|
Du solltest nur jQuery verwenden, um diese Klassen zu dem Element hinzuzufügen.
|
|
|
|
```js
|
|
assert(!code.match(/disabled[^<]*>/g));
|
|
```
