ajax - TYPO3 TCA 表单使用 AJAX 作为下拉列表

Question

在我的 TCA 表单中，我有两个下拉列表，List 1 calledCampus和 List 2 called Department。该Department列表应根据列表中选择的值而改变Campus。换句话说，Department列表取决于所选Campus项目。

如何在 TYPO3 TCA 表格中实现这一点？通常在 HTML 中，我会使用 AJAX，我应该在这里使用什么？

提前致谢 ：）

You can use markers in your "foreign_table_where"-string. One of them is the ###REC_FIELD_[fieldname]### marker.

Example:

'campus' => array(
    'label' => 'campus',
    'config' => array(
        'type' => 'select'
    )
    'foreign_table' => 'tx_myext_domain_model_campus',
),
'department' => array(
    'label' => 'department',
    'config' => array(
        'type' => 'select'
    )
    'foreign_table' => 'tx_myext_domain_model_department',
    'foreign_table_where' => " AND tx_myext_domain_model_department.campus = '###REC_FIELD_campus###'"
)

Additionally you have to tell TCA that a change of your campus field requests an update.

In ext_tables.php:

$TCA['tx_myext_domain_model_example']['ctrl']['requestUpdate'] .= ',campus';
