在视图中具有自动完成功能的搜索框

标签: jquery cakephp autocomplete cakephp-2.5

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 += '</div>';
                            js("#results").html(html);
                            js("#results").show('blind');
                    }
                    });
                    return false;

//select
            }).data( "ui-autocomplete" )._renderItem = function(ul, item){

            });
    })(jQuery);

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>

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。

1 个答案:

答案 0 :(得分: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'));
