嗨，我正在使用SAutoComplete（扩展了CAutoComplete），当从列表中选择一个值时，需要做一些工作。
我正在这样使用它。
this->widget('application.components.SAutoComplete', array('width'=>200,
'model'=>$cssAtapsClient, 'parseData'=>true, 'matchContains'=>true,
'attribute'=>'suburb_id', 'data'=>$postCode, 'ddindicator'=>true,
'max'=>50,
'multipleSeparator'=>false,
'options' => array(
'select' => new CJavaScriptExpression('function(e, ui) { alert("hi"); }')
),
)); ?>
我想知道为什么在自动完成的jquery UI中没有可用的选择选项？
选择示例如下。
$("#auto_cp").autocomplete({
minLength: 3,
//source
source: function(req, add) {
$.getJSON("friends.php?callback=?", req, function(data) {
var suggestions = [];
$.each(data, function(i, val) {
suggestions.push({
label: val.name,
zzz: val.zzz
});
});
add(suggestions);
});
},
//select
select: function(e, ui) {
alert(ui.item.zzz);
}
});

代码是这样的，
<?php
class SAutoComplete extends CAutoComplete
{
public $ddindicator;
/**
*
* @var boolean whether to parse the data assumes data uses an assoc array
* array(value => array(name, value, ...), ...). Only works with a model present
*/
public $parseData;
/**
* @var boolean whether to raise the change event
*/
public $raiseChangeEvent = false;
/**
* Initializes the widget.
* This method registers all needed client scripts and renders
* the autocomplete input.
*/
public function init()
{
if ( !$this->max )
$this->max = 50000;
if ( $this->ddindicator )
$this->alternateInit();
else
parent::init();
}
public function alternateInit()
{
list($name,$id)=$this->resolveNameID();
$this->htmlOptions['id'] = $id.'_input';
$this->minChars = 0;
echo CHtml::openTag('div', array('class'=>'ac-input-dd'));
echo CHtml::openTag('div', array('class'=>'ac-input-btn'));
echo CHtml::closeTag('div');
if($this->hasModel())
{
$htmlOpt = array();
if ( $this->parseData )
{
$menu = $this->data;
$key = $this->attribute;
//Change if attribute is apart of a array. eg attribute[0]
$pos1 = stripos($key, '[');
$pos2 = stripos($key, ']');
if($pos1!==false && $pos2!==false)
{
$key = str_replace (substr($key,$pos1,$pos2 - $pos1 + 1),'',$key);
$htmlOpt['value'] = isset($this->model->$key) ? $this->model->$key : '';
}
$this->value = isset($menu[$this->model->$key][0]) ? $menu[$this->model->$key][0] : '';
$this->data = is_array($menu) ? array_values($menu) : array('Error in data.');
}
echo CHtml::activeHiddenField($this->model, $this->attribute, array_merge(array('id'=>$id, 'name'=>$name), $htmlOpt));
echo CHtml::textField('', $this->value, $this->htmlOptions);
}
else
{
echo CHtml::hiddenField($name, $this->value, array('id'=>$id));
echo CHtml::textField($name.'_input',$this->value,$this->htmlOptions);
}
echo CHtml::closeTag('div');
$this->methodChain = $this->methodChain.'.result(function(evt, data, formatted) { $("#'.

'.parent().find(".ac-input-btn").mousedown(function(){'.

$this->registerClientScript();

public static function registerScript()

$cs->registerCoreScript('bgiframe');
TK::registerScriptFile('autocomplete');
$cs->registerCssFile($cs->getCoreScriptUrl().'/autocomplete/jquery.autocomplete.css');
}
/**

*/
public function registerClientScript()
{
// can cut this down once YII releases a fix for defect #38
if ( Yii::app()->request->isAjaxRequest || $this->ddindicator )
{
$id=$this->htmlOptions['id'];
$acOptions=$this->getClientOptions();
$options=$acOptions===array()?'{}' : CJavaScript::encode($acOptions);
$cs=Yii::app()->getClientScript();
if($this->data!==null)
$data=CJavaScript::encode($this->data);
else
{
$url=CHtml::normalizeUrl($this->url);
$data='"'.$url.'"';
}
if ( Yii::app()->request->isAjaxRequest )
{
echo '<script type="text/javascript">jQuery(document).ready('.
'function() {jQuery("#'.$id.'").autocomplete('.$data.','.$options.')'.
$this->methodChain.';});</script>';
}
else
{
SAutoComplete::registerScript();
$cs->registerScript('Yii.CAutoComplete#'.$id,"jQuery(\"#{$id}\").autocomplete($data,{$options}){$this->methodChain};");
}
}
else
parent::registerClientScript();
}
}
参考方案
尝试添加这个，
'methodChain'=>".result(function(event,item){ urFunction(); })",
祝你今天愉快！
所以最后看起来像
$this->widget('application.components.SAutoComplete', array('width'=>200,
'model'=>$cssAtapsClient, 'parseData'=>true, 'matchContains'=>true,
'attribute'=>'suburb_id', 'data'=>$postCode, 'ddindicator'=>true,
'max'=>50,
'methodChain'=>".result(function(event,item){ urFucntion(); })",
));
