Setting new value for an attribute using jQuery

Question

I am trying to set a new vale of a custom attribute of a div using attr(). I found out it can be done using .attr( attributeName, value ), but when I try it it's not working.

Here is the part of my code I am interested in:

$('#amount').attr( 'datamin','1000')

and the div that has the custom attribute is

<div id="amount" datamin=""></div>

Here is the whole example:

$(function() {
    $( "#slider-range" ).slider({
        range: true,
        min: <?php echo $min_val;?>,
        max: <?php echo $max_val;?>,
        values: [ <?php echo $min_val;?>, <?php echo $max_val;?> ],
        slide: function( event, ui ) {
            $( "#amount" ).html( "<?php echo $currency_chk_i;?>" + ui.values[ 0 ] + " - <?php echo $currency_chk_i;?>" + ui.values[ 1 ] );

            $('#amount').attr( 'datamin','1000');

        },
        change: function(event, ui) {
            // when the user change the slider
        },
        stop: function(event, ui) {
        alert(ui.values[0]);
            // when the user stopped changing the slider

        }
    });
    $( "#amount" ).html( "<?php echo $currency_chk_i;?>" + $( "#slider-range" ).slider( "values", 0 ) +
        " - <?php echo $currency_chk_i;?>" + $( "#slider-range" ).slider( "values", 1 ) );

});

Can anyone point out where I am wrong or any other way out?

actually it a part of my code . i think i should put up my whole code it not working in tht — Sakshi Sharma, Aug 03 '12 at 10:44
You should use html5's new data attribute instead, which will give you valid markup. It works like this:
and JS: $('#amount').data('nameofdata', new value); — ninja, Aug 03 '12 at 10:45
try putting alert($('#amount').attr( 'datamin')); straight after $('#amount').attr( 'datamin','1000'); you can test the event fires as expected and if the code has done its job — Blowsie, Aug 03 '12 at 10:51
where / why are you udsing this data min anyway? your code doesn't show what you are actually setting it for — Blowsie, Aug 03 '12 at 10:52

Works fine for me

See example here. http://jsfiddle.net/blowsie/c6VAy/

Make sure your jquery is inside $(document).ready function or similar.

Also you can improve your code by using jquery data

$('#amount').data('min','1000');

<div id="amount" data-min=""></div>

Update,

A working example of your full code (pretty much) here. http://jsfiddle.net/blowsie/c6VAy/3/

It is working you have to check attr after assigning value

LiveDemo

$('#amount').attr( 'datamin','1000');

alert($('#amount').attr( 'datamin'));
