Now I need a three level selected option, and the second selected option will change with first selected option's value,so I use the jquery plugin "select box manipulation" can do it, but now I use codeigniter, so I want to integrate it using libraries, how can do it?
How can I integrate jquery select box manipulation incodeigniter? Do I need to use a library, or are there other methods to do it?
Who can give me some point? http://www.texotela.co.uk/code/jquery/select/
No, you don't need a library. Just create methods in your controller to get data for your forms.
One idea would be to return the respective form field to the request to be populated in a div or something.
View:
<select name="shirts" onchange="getField(this.value)">
<option value="small">Small Shirt</option>
<option value="med">Medium Shirt</option>
<option value="large" selected="selected">Large Shirt</option>
<option value="xlarge">Extra Large Shirt</option>
</select>
<div id="field2"></div>
Javascript:
function getField(val){
$.ajax({
type:"get",
url: "/controller/getField/"+val,
success: function(data){
$('#field2').html(data);
}
});
}
Controller:
...
public function getField($val=''){
switch($val){
case 'small':
//$options = get data and do stuff;
echo form_dropdown('shirts', $options, 'large');
break;
}
}
