Simultaneous jQuery Animations

Question

I'm trying to get both a fadeIn (opacity toggle) and border fade (using jquery-animate-colors) to fire simultaneously but I'm having some trouble. Can someone help review the following code?

$.fn.extend({
  key_fadeIn: function() {
    return $(this).animate({
      opacity: "1"
    }, 600);
  },
  key_fadeOut: function() {
    return $(this).animate({
      opacity: "0.4"
    }, 600);
  }
});

fadeUnselected = function(row) {
  $("#bar > div").filter(function() {
    return $(this).id !== row;
  }).key_fadeOut();
  return $(row).key_fadeIn();
};

highlightRow = function(row, count) {
  return $(row).animate({
    "border-color": "#3737A2"
  }).animate({
    "border-color": "#FFFFFF"
  }).animate({
    "border-color": "#3737A2"
  }).animate({
    "border-color": "#FFFFFF"
  });
};


fadeUnselected("#foo");
highlightRow("#foo"); // doesn't fire until fadeUnselected is complete

Would really appreciate it. Thanks!

By default, JQuery places animations in the effects queue so they will happen one after another. If you want an animation to happen immediately set the queue:false flag in your animate options map.

For example, in your case,

$(this).animate({
      opacity: "1"
    }, 600);

would become

$(this).animate(
{
    opacity: "1"
}, 
{
    duration:600,
    queue:false
});

You'd likely want to use the options map and set the queue for the border animation as well.
