Question

I am using this plug in. All works well, but now i need to make a change.
the callback always made the last condition – else, why?

this condition for example never works. Any syntax error?

($("#amount").val(value) == 400)

script

 <script type="text/javascript" charset="utf-8">
     jQuery("#SliderSingle").slider({
         from: 400,
         to: 2000,
         step: 200,
         round: 1,
         dimension: '&nbsp;€',
         scale: ['-400€', '600€', '800€', '1000€', '1200€', '1400€', '1600€', '1800€', '+2000€'],
         callback: function(value) {
             if ($("#amount").val(value) == 400) { //not working
                 alert("nop");
                 $(html("-400 sdf"));
             }
             else if ($("#amount").val(value) == 2000) {  //not working
                 alert("nopp");
                 $(html("+2000 dfs"));
             } else {
                 $(html(value)); //always working even if the value chosen is 400 or 2000
             }
         }
     });
 </script>

Looks like you want this:

function(value) {
    if (value == 400) {
        alert("nop");
        $(html("-400 sdf"));
    }
    else if (value == 2000) { 
        alert("nopp");
        $(html("+2000 dfs"));
    } else {
        $(html(value)); //always working even if the value chosen is 400 or 2000
    }
}

Although $(html("-400 sdf")); won’t work. Unless you’ve defined a html() function
