I am trying to access the selected value of the ESelect2 extension and display it and use it with javascript when a button is clicked
ESelect2
echo CHtml::textField('cas', '', array('class' => 'span5'));
$this->widget('ext.select2.ESelect2', array(
'selector' => '#cas',
'options' => array(
'placeholder' => 'Search Code',
//'minimumInputLength' => 1,
'ajax' => array(
'type' => 'GET',
.
.
.
Alert Button
echo CHtml::button("(+)",array('title'=>"Topic",'onclick'=>'js:var data = $("#cas").select2("data"); alert(data.text);'));
Using the code above, the alert popup box is empty. I really appreciate any help with this.
I resolved the issue I was having. The issue was with the ‘results’ option in the ajax array. Apologies, I should have posted all the code.
New working code:
echo CHtml::textField('cas', '', array('class' => 'span5','style' => 'min-width:150px;'));
$this->widget('ext.select2.ESelect2', array(
'selector' => '#cas',
'options' => array(
'placeholder' => 'Search Code',
//'minimumInputLength' => 1,
'ajax' => array(
'type' => 'GET',
'url' => $this->createUrl('xyz/AutoComplete',array('modelid'=>$model->id,'itemtype'=>'Cas')),
'dataType' => 'json',
'data' => 'js: function(term, page) {
return {
term: term,
};
}',
'results' => 'js: function(data){
return {
results :
data.map(function(item) {
return {
id : item.id,
text : item.value
};
}
)};
}',
),
'formatResult' => 'js:function(movie){
return movie.id + " " + movie.text;
}',
'formatSelection' => 'js: function(movie) {
return movie.text;
}',
),
));
?>
Before the fix, I had the following for the ‘results’ option.
'results' => 'js: function(data){
return {results: data};
}',
