hi there, im using jquery ui to create my sliders from a select input. My code works in that it calls a function everytime the slider value changes but ui.value only passes the numerical value of the option rather than the the actual value of the select box, how do i fix this?

my code:

$('#budget').selectToUISlider({
labels: 0,
sliderOptions: {
change:function(e, ui) {
paging('1', '','','1', ui.value , '','' , '');
}
}
});


<select name="budget" id="budget">
  <option value="option1" selected="selected">All</option>
  <option value="option2">asd</option>
  <option value="option3" >dfsdf</option>
  <option value="">sdfsdf</option>
</select>
EXAMPLE: looking at the select above, i want the code to pass the value "option1" to my function, however ui.value only passes "1" while otion 2 passes "2" and so on.

I don't know jQuery, but I'm assuming the value is the index of the option, so, try ...

$('#budget').option(ui.value).value

Can you try ...


change:function(e, ui) {
alert(ui);
alert(ui.value);
paging('1', '','','1', ui.value , '','' , '');
}


Oh. Is it ...

paging('1', '','','1', $('#budget').options(ui.value).value , '','' , '');

tried that but it didnt work, ive been looking at the slider ui documentation, i think it might be one of the methods but im not sure how to implement them.

    .slider( 'option' , optionName , [value] )

or maybe

    .slider( 'value' , [value] )

Can you change ...

paging('1', '','','1', ui.value , '','' , '');

to

alert(ui.value); // Should be the value.

Does the value change appropriately?

If so, change this to ...

alert(parseInt(ui.value)); // Should still be the value but as a number rather than a string.
alert($('#budget').name); // Should be budget.
alert($('#budget').options); // Should be an array.
alert($('#budget').options(parseInt(ui.value,10)); // Should be an option object.
alert($('#budget').options(parseInt(ui.value,10).value); // Should be the value for the option.

.slider('option', ...) is about getting the SLIDER's options, not the SELECT's <option>'s.

Right. Can you show me the complete HTML source? Ideally an online link.

I use prototype, not jquery, so my syntax may be off.

With $('#budget') I want to get the select which id is 'budget'.

Then I want to find the options property (which is the list of options on the select).

Then I want to find the specific option as specified by ui.value.

Then I want to find the value attribute for that option.

Hi.

Got it working.

Change the locations of the JS files.

I didn't get a slider (not sure what you need for that).

It didn't look nice in FF or Chrome, but the selecting worked in FF (I just wanted the debugs).

Run the script below in Firefox with Firebug.


Essentially, the important bit is ...

$('#posted')[0].options[parseInt(ui.value,10)].text

or

$('#posted')[0].options[parseInt(ui.value,10)].value

depending upon what you want to use.
<html>
<head>
<script type="text/javascript" src="file:///Z:/slider/js/jquery-1.3.2.min.js"></script>
<script type="text/javascript" src="file:///Z:/slider/js/jquery-ui-1.7.1.custom.min.js"></script>
<script type="text/javascript" src="file:///Z:/slider/js/selectToUISlider.jQuery.js"></script>
</head>
<body>
<select name="posted" id="posted"> 
  <option value="" selected="selected">All</option> 
  <option value="1246804007"> Less than 24 Hours ago</option> 
  <option value="1246717607" >Less than 2 days ago</option> 
  <option value="1246631207">Less than 3 days ago</option> 
  <option value="1246544807">Less than 4 days ago</option> 
  <option value="1246458407">Less than 5 days ago</option> 
  <option value="1246372007">Less than 6 days ago</option> 
  <option value="1246285607">Less than 7 days ago</option> 
  <option value="1245680807">Less than 2 weeks ago</option> 
</select>
<script type="text/javascript">
$
    (
    function()
        {
        $('#posted')
            .selectToUISlider

                    {

                            {
                            console.info('parseInt(ui.value, 10)', parseInt(ui.value));
                            console.info('#posted[0]', $('#posted')[0]);

                            console.info('#posted[0].options[parseInt(ui.value, 10)].value', $('#posted')[0].options[parseInt(ui.value,10)].value);
