How to get drop down value dynamically in JavaScript?
Question
I have a dropdown list in PHP Zend with the following code :
$this->addElement('select', 'target', array(
'decorators' => $this->getElementDecorators(),
'label' => Zend_Registry::get('Zend_Translate')->translate('Target_Platform'),
'style' => 'width:320px;',
'data-help' => Zend_Registry::get('Zend_Translate')->translate('Target_Platform_To_Publish_To'),
));
This has a list of about 14 values.
I am using below code in my JS file to get the CURRENT drop-down value :
this.temp = $('#target :selected').text();
console.dir(this.temp);
However the value in this variable does not changes when I select some other value in the dropdown ? I want the variable to change dynamically as per the values selected by the user.
How is that possible ? Thanks for reading :)

You can use .select event to do this.
$(document).ready(function(){
$("#target").select(function(){
console.log($(this).val());
});
});
And i hope that you have included jQuery file
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
EDIT
<body>
.....
// At the end of the body because JS loads Synchronously
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.11.2/jquery.min.js"></script>
</script>
$(document).ready(function(){
$("#target").select(function(){
console.log($(this).val());
});
});
</script>
</body>

This worked .
$('#target').on('change', function () {
var data = {
platform: $('#target :selected').text()
};
console.log(data);

Try binding this.temp = $('#target :selected').text(); to some event( .select ), So when event get fired the desired code will get executed. From current approach , this.temp = $('#target :selected').text(); will get executed only when the document is loaded giving the default value.
