How do I set a visible property of a div element to true or false in jquery?

I would like to be able to do this:

$(".panel").visible = true;

but this 开发者_JS百科doesn't work.

For the display CSS property, use .show(), .hide() or .toggle() to affect whether it displays, like this:

$(".panel").show();
//or to hide:
$(".panel").hide();
//toggle show/hide
$(".panel").toggle();
//or show/hide based on boolean:
$(".panel").toggle(bool);

For the visibility CSS property, you need to set it manually (jQuery is mostly built around display), using .css() like this:

$(".panel").css("visibility", "visible");
//or:
$(".panel").css({ visibility: "visible"});

For me this worked:

document.getElementById('my_elementid').style.visibility='visible';

you can by using ClientScript on serverside call your jquery method

ClientScript.RegisterStartupScript(this.GetType(), "hideslidertab", "hideslidertab();", true);
