Question

我是cakephp的新手，我已经按照教程实现了自动完成的搜索框，一切顺利，View / Pages / home.ctp的搜索框按预期工作，但我真的需要放我的View / Terms / index.ctp上的搜索框，我找不到让它工作的方法，在这里我粘贴了我生成的所有代码，希望有人可以帮助我，并提前感谢：

file：Controller / TermsController.php

<?php
App::uses('AppController', 'Controller');
class TermsController extends AppController {
    public $helpers = array('Js'=>'Jquery', 'Form', 'Html');
    public $components = array('Paginator', 'RequestHandler', 'Session');
    public function getdata($id = null){
            $this->Term->id = $id;
            if(!$this->Term->exists()):
                    throw new NotFoundException("El terme no existeix");
            endif;
            $this->set('term', $this->Term->read(null, $id));
            $this->layout = 'ajax';
    }

    public function autocomplete(){
            $this->set('terms', $this->Term->find('all', 
            array('conditions' => array(
            'Term.entry LIKE' => $this->request->query['term'].'%'),
            'fields' => array('id', 'entry')
            )
    ));
    $this->layout = 'ajax';
    }

    public function index() {
            $this->Term->recursive = 0;
            $this->set('terms', $this->Paginator->paginate());
    }
}

file：View / Pages / home.ctp（有效的那个）

<?php $this->layout = 'default';?>
<?php   echo $this->Form->create(null,array());
    echo $this->Form->input('word', array('label' => 'Cerca entrada'));
    $this->Form->end('Cerca'); ?>
<div id="results"></div>
   <script type="text/javascript">
    var js = jQuery.noConflict();
    (function($){
            js(document).ready(function(){
            js("#results").hide();
//Autocomplete
            js( "#word" ).autocomplete({
                    source: "terms/autocomplete",
                    minLength: 3,
                    focus: function(event, ui){
                    js("#word").val(ui.item.Term.entry); return false;
                    },
                    select: function( event, ui ) {
                    js( "#word" ).val(ui.item.Term.entry);
                    var id = ui.item.Term.id;
                    $.ajax({
                            url: 'terms/getdata/'+id,
                            dataType: 'json',
                            success: function(data){
                            var html = '<div class="lemma_tag">';
                                    html += '<h2>Lemes i etiquetes</h2>';
                                    html += '<p>'+data.Term.lemma_tag+'</p>';
                                    html += '<p><a href="terms/view/'+id+'">Més accions</a></p>';
                                    html += '</div>';
                            js("#results").html(html);
                            js("#results").show('blind');
                    }
                    });
                    return false;
}
//select
            }).data( "ui-autocomplete" )._renderItem = function(ul, item){
                    return $("<li></li>")
                            .data("ui-autocomplete-item", item)
                            .append("<a>" + item.Term.entry + "</a>")
                            .appendTo(ul)
            };
//Autocomplete.end
            });
    })(jQuery);
    </script>

档案：查看/条款/ autocomplete.ctp

<?php echo $this->Js->object($terms);?>

档案：查看/条款/ getdata.ctp

<?php echo $this->Js->object($term); ?>

file：View / Terms / index.ctp（这里它不起作用，我粘贴整个文件让你知道我想要实现的目标）< /强>

<div class="terms index"> <h2><?php echo __('Terms'); ?></h2> <table cellpadding="0" cellspacing="0"> <tr> <th><?php echo $this->Paginator->sort('id'); ?></th> <th><?php echo $this->Paginator->sort('entry', 'Entrada'); ?></th> <th><?php echo $this->Paginator->sort('lemma_tag', 'Lemes i etiquetes'); ?></th> <th><?php echo $this->Paginator->sort('status', 'Estat'); ?></th> <th class="actions"><?php echo __('Actions'); ?></th> </tr> <?php foreach ($terms as $term): ?> <tr> <td><?php echo h($term['Term']['id']); ?> </td> <td><?php echo h($term['Term']['entry']); ?> </td> <td><?php echo h($term['Term']['lemma_tag']); ?> </td> <td><?php echo h($term['Term']['status']); ?> </td> <td class="actions"> <?php echo $this->Html->link(__('View'), array('action' => 'view', $term['Term']['id'])); ?> <?php echo $this->Html->link(__('Edit'), array('action' => 'edit', $term['Term']['id'])); ?> <?php echo $this->Form->postLink(__('Delete'), array('action' => 'delete', $term['Term']['id']), array(), __('Are you sure you want to delete # %s?', $term['Term']['id'])); ?> </td> </tr> <?php endforeach; ?> </table> <p> <?php echo $this->Paginator->counter(array( 'format' => __('Page {:page} of {:pages}, showing {:current} records out of {:count} total, starting on record {:start}, ending on {:end}') )); ?> </p> <div class="paging"> <?php echo $this->Paginator->prev('< ' . __('previous'), array(), null, array('class' => 'prev disabled')); echo $this->Paginator->numbers(array('separator' => '')); echo $this->Paginator->next(__('next') .

解决方案：

对于那些面临同样问题的人来说，@ Saline的优秀答案的第二部分是使其有效的部分：echo $this->Form->input('word', array('id'=>'word','label' => 'Cerca entrada'));建议的第一个更改是不必要的。

Answer 1

尝试替换这行代码：

source: "terms/autocomplete",
...
url: 'terms/getdata/'+id,

在此：

source: "<?php echo $this->Html->url(array('controller' => 'terms','action' => 'autocomplete'),true);?>",
url: "<?php echo $this->Html->url(array('controller' => 'terms','action' => 'getdata'),true) .'/';?>" +id,

要理解差异，如果您在javascript代码中放置了静态路径"terms/autocomplete"，那么从您的主页javascript有正确的帖子/获取网址，但是当您在条款页面上时，会生成javascript url eg / terms / terms / autocomplete。

更新：将id =“word”添加到您的输入字段

echo $this->Form->input('word', array('id'=>'word','label' => 'Cerca entrada'));

在视图中具有自动完成功能的搜索框
