Check if DIV is visible using javascript

Question

i needed to hide a div on my code behind:

bool hideDiv = false
//codes to change hideDiv
myDiv.visible = hideDiv;

and i want to check visibility of my div using javascript:

if (jQuery("myDiv") != null){
    //some codes
}
else{
    //some codes
}

and the 'jQuery("myDiv")' is always not null (even if the div was actually not visible), what is the better way to check if a div is visible?

Answer 1

You can use :visible selector inside is filtering function :

if ($('#myDiv').is(':visible'))

Notes:

• You probably forgot the # before the id in your selector( jQuery("myDiv") ).
• jQuery will never return null no matter if the searched elements exist or not, unlike document.getElementById
