How to disable button url in Magento 2?

Question

I tried to put # places of the url, but the url still works and e.stopImmediatePropagation () with js also didn't help. Is there any way to do this through xml or otherwise? Thanks

 <item name="buttons" xsi:type="array">
            <item name="alert_text" xsi:type="array">
                <item name="name" xsi:type="string">alert_text</item>
                <item name="label" xsi:type="string" translate="true">Custom Button</item>
                <item name="class" xsi:type="string">primary</item>
                <item name="url" xsi:type="string">*/*/url</item>
            </item>
        </item>

Answer 1

use this in a button

<item name="disabled" xsi:type="boolean">true</item>

Ok, I got your concern. Try the below line. It adds a url but it does not work on click.

  <item name="url" xsi:type="string">'#'</item>

Answer 2

When using a block I was able to set url as null and that worked for me.

use Magento\Framework\View\Element\UiComponent\Control\ButtonProviderInterface;

class saveData implements ButtonProviderInterface
{
    /**
     * @return array
     */
    public function getButtonData()
    {
        return [
            'label' => __('Save'),
            'class' => 'save primary',
            'data_attribute' => [
                'mage-init' => [
                    'buttonAdapter' => [
                        'actions' => [
                            [
                                'targetName' => 'targetname.targetname',
                                'actionName' => 'youractionname',
                                'params' => [
                                    false
                                ]
                            ]
                        ]
                    ]
                ],
                'form-role' => 'save',
            ],
            'url' => null,
            'sort_order' => 90,
        ];
    }


}
