JS control display and hide compatibility issues (IE6, IE7, IE8)_javascript skills

In IE7,

Use jQuery

Display: $("#a").attr("style","");

Hide: $("# a").attr("style","display:none");

But this method of displaying does not work in IE8

IE8

Display: $("# a").removeAttr("style");

Hide: $("#a").attr("style","display:none");

IE6, the weirdest , using display:none cannot hide the select tag

The following two, after testing, can be used normally in three versions

Hide: document.getElementById("a").style .display="none";

Display: document.getElementById("a").style.display="";
