javascript tutorial - [Solved-5 Solutions] Hidden element - javascript - java script - javascript array
Problem:
How would we test if an element is visible or hidden ?
Solution 1:
// Checks for display:[none|block], ignores visible:[true|false]
$(element).is(":visible"); click below button to copy the code. By JavaScript tutorial team
Solution 2:
// Matches all elements that are hidden
$('element:hidden')
And the visible selector:
// Matches all elements that are visible
$('element:visible')click below button to copy the code. By JavaScript tutorial team
Solution 3:
if ( $(element).css('display') == 'none' ){
// element is hidden
}click below button to copy the code. By JavaScript tutorial team
Functions don't work with the visibility attribute.
Solution 4:
None of these answers address what we understand to be the question, which is what we was searching for, "How do I handle items that have visibility: hidden?". Neither :visible nor :hidden will handle this, as they are both looking for display per the documentation. As far as I could determine, there is no selector to handle CSS visibility. Here is how I resolved it (standard jQuery selectors, there may be a more condensed syntax):
$(".item").each(function() {
if ($(this).css("visibility") == "hidden") {
// handle non visible state
} else {
// handle visible state
}

Solution 5:
You can determine whether an element is collapsed or not by using the :visible and :hiddenselectors.
var isVisible = $('#myDiv').is(':visible');
var isHidden = $('#myDiv').is(':hidden');click below button to copy the code. By JavaScript tutorial team
If you're simply acting on an element based on its visibility, you can just include :visible or :hidden in the selector expression. For example:
$('#myDiv:visible').animate({left: '+=200px'}, 'slow');
