问题:

I would expect the following code to start my slider at '30' in it's range of 0-250, but yet it is not.

$(function() {
  $( "#slider" ).slider({
  value: 30,
  min: 0, 
  max: 250,
  step: 1, 
  slide: function(event, ui){
    $("#edit-varprice").val(ui.value + ".00");
  }  
  });
});

Its working fine for me. See jsFiddle Demo.

Perhaps you are missing something else or doing something in other parts of your code, can you post full code?

回答2:

try removing the value from the options u chose, and adding it later using:

$( "#slider" ).slider( "option", "value", 40 );

Could you lower your max to 50 and see if the slider handle is offset, if so then its working just fine. In the image it looks like its slightly offset. 30/250 is only 12% and may be deceiving.
