添加回调以显示：

  $（＃progressbar_area）。show（speed，function（）{} ）; 
 

动画完成后，回调函数将被调用。

I can't make my div visible with the jquery show() until my function is over! It actually works in IE/FF but not in Chrome. How can I make sure my element is visible before continuing with my function?

Here's my code:

function doOperation(){
    $("#progressbar_area").show();
    (...)
}

Add a callback to show:

$("#progressbar_area").show(speed, function() {});

The callback function will be called when the animation is complete.
