# --description--
|
|
|
|
You can also change the non-CSS properties of HTML elements with jQuery. For example, you can disable buttons.
|
|
|
|
When you disable a button, it will become grayed-out and can no longer be clicked.
|
|
|
|
jQuery has a function called `.prop()` that allows you to adjust the properties of elements.
|
|
|
|
Here's how you would disable all buttons:
|
|
|
|
```js
|
|
$("button").prop("disabled", true);
|
|
```
|
|
|
|
Disable only the `target1` button.
|
|
|
|
# --hints--
|
|
|
|
Your `target1` button should be disabled.
|
|
|
|
```js
|
|
assert(
|
|
$('#target1') &&
|
|
$('#target1').prop('disabled') &&
|
|
code.match(/["']disabled["'],( true|true)/g)
|
|
);
|
|
```
|
|
|
|
No other buttons should be disabled.
|
|
|
|
```js
|
|
assert($('#target2') && !$('#target2').prop('disabled'));
|
|
```
|
|
|
|
You should only use jQuery to add these classes to the element.
|
|
|
|
```js
|
|
assert(!code.match(/disabled[^<]*>/g));
|
|
```
