php - Javascript 确认删除

Question

我正在创建一个简单的 cms，我有以下内容

<input type="submit" value="delete" title="Delete Aricle(s)" id="delete_btn" onclick="delete_confirm()" />

<tbody>
  <?php foreach ($articles as $article): ?>
  <tr>
    <td align="center">
    <input id="article_id"name="article[]" type="checkbox" value="<?php echo $article->id; ?>" /></td>
    <td align="center"><?php echo anchor('admin/articles/edit/'.$article->id,$article->title); ?></td>
    <td align="center"><?php echo $article->author; ?></td>
    <td align="center"><?php echo $article->category; ?></td>
    <td align="center"><?php published($article->post_status); ?></td>
    <td align="center"><?php featured($article->featured); ?></td>
    <td align="center"><?php echo $article->views; ?></td>
    <td align="center"><?php echo $article->post_date; ?></td>
  </tr>
  <?php endforeach;?>
  </tbody>

上面的代码包裹在一个表单标签中

这是我的javascript代码

function delete_confirm() {
    var msg = confirm('Are you sure you want to delete the selected article(s)');
    if(msg == false) {
        return false;
    }
}

这是我 Controller 中的删除功能

function articles_delete() {
        //Load Model
        $this->load->model("article_model");
        //Assign article id to variable
        $checkbox = $_POST['article'];
        //loop through selected checkbox
        for($i = 0; $i < count($checkbox); $i++) {
            //Call delete method of the article model
            $this->article_model->delete($checkbox[$i]);
        }
        $this->session->set_flashdata("message","Article(s) Deleted");
        redirect("admin/articles","refresh");
     }

但是当在确认对话框中单击取消时，表单仍然被提交并且所选文章被删除。 请指点一下该怎么做

尝试改变

<input type="submit" value="delete" title="Delete Aricle(s)" id="delete_btn" onclick="delete_confirm()" />

到

<input type="submit" value="delete" title="Delete Aricle(s)" id="delete_btn" onclick="return delete_confirm();" />

您正在 onclick 函数内部运行 delete_confirm() 函数。您需要从 onclick() 函数本身返回 false。
