What should I do if the jquery control fails?

About jquery's problem of hiding and displaying controls

Generally, if we want to dynamically display or hide html jsp controls, we can use jquery's own methods

 $("#id").hide();
 
 $("#id").show();

But sometimes when we dynamically control the hiding or display of elements in the control, failure may occur.

For example, if th tr in a div or li in ul hide the div ul, it may not be possible to hide the controls inside, so this will fail.

Solution:

   $("#xxx").hide("slow",function(){$(this).css("display","none")}); 
 
   $("#xxx").show("slow",function(){$(this).css("display","block")});

For the slow function, I looked at the source code and found that it is a speed control for hiding or displaying.

Optional parameters include fast and _default.

As for the choice, it depends on your own preferences.
