我想在用户个人资料页面中添加一个表单。所以我创建了 user-profiled.tpl.php。在该模板中,我只是从 ajax 框架中复制了示例进行测试。这是整个代码:
function ajax_example_simplest($form, &$form_state) {
$form = array();
$form['changethis'] = array(
'#type' => 'select',
'#options' => array(
'one' => 'one',
'two' => 'two',
'three' => 'three',
),
'#ajax' => array(
'callback' => 'ajax_example_simplest_callback',
'wrapper' => 'replace_textfield_div',
),
);
$form['replace_textfield'] = array(
'#type' => 'textfield',
'#title' => t("The default value will be changed"),
'#description' => t("Say something about why you chose") . "'" .
(!empty($form_state['values']['changethis'])
? $form_state['values']['changethis'] : t("Not changed yet")) . "'",
'#prefix' => '<div id="replace_textfield_div">',
'#suffix' => '</div>',
);
return $form;
}
function ajax_example_simplest_callback($form, $form_state) {
return $form['replace_textfield'];
}
我现在很困惑。单击复选框后,文本字段中没有任何变化。我的 jquery 版本是 1.9。还有其他限制吗?
