Why does the jquery ui slider return an object?

问题

When I do

console.log($('#my_slider').slider('value'))

it returns [object Object] Does anyone know why it doesn't return the actual value of the slider like it says it is supposed to in the documentation?

回答1:

You should use (here doc)

console.log($('#my_slider').slider( "option", "value" ))

回答2:

This is to allow method chaining.

The returned object that you are seeing is the original matched set (#my_slider). So, if you had other jQuery methods to call on this you could add them to the end of your statement.

$('#my_slider').slider('value').othermethod();

This works for .draggable and should work for .slider too

$(function() {
    $( "#slider" ).slider(
       stop: function (s) {
          console.log(s);
       }
    );
});

This code works for me on the demo page for slider:

$('#slider').slider('value');

Here: http://jqueryui.com/resources/demos/slider/hotelrooms.html

Might want to look at your implementation.
