我正在研究Drupal 7,我有一个像这样构建的表单
function qt_debate_response_form($form, &$form_state, $node_id){
$form['node_id'] = array(
'#type' => 'value',
'#value' => $node_id,
);
$form['response_body'] = array(
'#type' => 'textarea',
'#required' => TRUE,
'#row' => 4,
'#default_value' => '',
);
$form['submit'] = array(
'#type' => 'submit',
'#value' => t('Post'),
'#ajax' => array(
'callback' => 'qt_debate_response_form_js',
'wrapper' => 'response-message-' . $node_id,
'method' => 'append',
'effect' => 'fade',
),
);
return $form;
}
一个用于添加新评论的ajax回调函数
function qt_debate_response_form_js($form, $form_state) {
global $user;
$body_text = $form_state['values']['response_body'];
$node_id = $form_state['values']['node_id'];
$message_js = '
<script language="javascript" type="text/javascript">
qt_debate_response_load_new_item(' . $node_id . ',' . $user->uid . ');
jQuery(".response-form-wrapper textarea").val("");
</script>';
$comment = new stdClass();
$comment->nid = $form_state['values']['node_id']; // Node Id the comment will attached to
$comment->cid = 0;
$comment->pid = 0;
$comment->uid = $user->uid;
$comment->is_anonymous = 0;
$comment->homepage = '';
$comment->status = COMMENT_PUBLISHED;
$comment->language = LANGUAGE_NONE;
$comment->subject = text_summary($body_text, null, 60);
$comment->comment_body[$comment->language][0]['value'] = $body_text;
$comment->comment_body[$comment->language][0]['format'] = 'filtered_html';
comment_submit($comment);
comment_save($comment);
$output = $message_js;
return $output;
}
这是我的Javascript,它将新创建的评论加载到Div(ajax)
function qt_debate_user_post_load_new_items(debate_id) {
// get the latest comment id in context
$top_comment = jQuery(".view-debate-user-posts .views-row").first();
$top_comment_id = jQuery(".nid-field-hidden", $top_comment).html();
jQuery.ajax({
type: "GET",
url: "/qt_debate/ajax/load_new_items/" + debate_id + "/" + $top_comment_id,
data: "",
success: function(html){
$new_items = jQuery(".view-content", html);
jQuery("form", $new_items).attr("action","/debate/199");
jQuery(".form-submit", $new_items).attr("id","edit-submit--5");
if ($new_items.html() != null) {
html = '<div class="new_items_wrapper" style="display: none">' + $new_items.html() + '</div>';
if (jQuery(".view-debate-user-posts .view-content").length == 0) {
jQuery(".view-debate-user-posts .view-empty").remove();
jQuery(".view-debate-user-posts").append('<div class="view-content"></div>');
}
jQuery(".view-debate-user-posts .view-content").prepend(html);
jQuery(".view-debate-user-posts .view-content .new_items_wrapper").fadeIn(500, function() {
jQuery(".views-row", this).unwrap();
Drupal.attachBehaviors();
});
}
},
});
var t = setTimeout("qt_debate_user_post_load_new_items(" + debate_id + ")", 30000)
}
将视图内容返回给jQuery回调的hook_menu
function qt_debate_ajax_load_new_items() {
$debate_id = arg(3);
print views_embed_view('debate_user_posts_load_new_items_', 'default', array($debate_id));
exit(0);
}
查看模板文件,我还在
中返回一个新表单print drupal_render(drupal_get_form('qt_debate_response_form', $row->nid));
返回视图内容呈现良好,使用Javascript中的Drupal.attachBehaviors,返回的视图内容中的所有其他效果也很有效。表格提交ajax除外。
任何人都可以帮忙吗? attachBehaviors不能与返回ajax表单一起使用。
非常感谢!
答案 0 :(得分:0)
Drupal.attachBehaviors(context);
基本上重新运行
定义的任何函数Drupal.behaviors.yourFunctionName = function(context) {
$('div.someSelectorclass:not(.already-processed-class)', context).addClass('already-processed-class').bind(someMethod);
}
并且这些方法必须添加一个选择器[already-processed-class]来测试是否bind(); [或点击(function(e){});或者每个(function(){});或其他任何]已被添加。 “上下文”是传递少于'文档' - 比如,如果您的新内容已知在原始行为函数仍然可以找到的较小上下文中:在此示例中,我可以传递我的父容器选择器新的'div.someSelectorclass'
Drupal.attachBehaviors('div.parentContainerClass');
而不是
Drupal.attachBehaviors(document);
