jQuery if any of a certain class is hidden perform a task, else, perform another task
Is there a way to test if a certain element (.container) is hidden, in a whole document? Such as (which doesn't work properly):
$(".showall").click(
function () {
if ($(".container").is("hidden"))
{perform a task}
else
{retur开发者_如何转开发n false;}
});
It sounds like you want to test if at least one of the .container
elements is hidden.
If so, you can use the :hidden
selector, and check the length
property to see how many were returned.
$(".showall").click(
function () {
if ($(".container:hidden").length)
// found at least one hidden
else
// didn't find any hidden
});
If you wanted to test to see if all were hidden, use the :visible
selector like this:
$(".showall").click(
function () {
if ($(".container:visible").length)
// found at least one visible
else
// didn't find any visible
});
You mean to use is visible:
$(".showall").click(
function () {
if ($('.container').is(":visible") == false)
{perform a task}
else
{return false;}
});
