How to hide a div when the user clicks outside of it using jQuery?
An element can be hidden or shown based on if the mouse is clicked outside the element using two methods.
Method 1: Using the closest method:
- A mouseup event is to first checked upon the document
$(document).mouseup(function(e) {// rest code here} - The closest() method is called on the target click. This method returns the first ancestor of the selected element in the DOM tree. The length property is then used on the result to find out the number of ancestors. If there are no ancestors, it means that the click was outside the element.
if($(e.target).closest(".container").length === 0) {// rest code here} - The element is hidden using the hide() method.
$(".container").hide(); - Clicking inside the div:
- Clicking outside the div:
- A mouseup event is to first checked upon the document
$(document).mouseup(function(e) {// rest code here} - The element is checked for 2 things, that the click does not land on the element by passing the is() method and the has() method with the click target.
The is() method check the current element against the specified element. The click target is passed as a parameter and the whole result is negated to essentially check if the click was outside the element.
The has() method is used to return all the elements which match at least one of the elements passed to this method. The length property is then used on the result to check if any elements are returned. If there are no elements returned, it means that the click was outside the element.
if(!container.is(e.target) && container.has(e.target).length === 0) {// rest code here} - The element is hidden using the hide() method.
$(".container").hide(); - Clicking inside the div:
- Clicking outside the div:
Example:
<!DOCTYPE html> <html> <head> <title> How to hide a div when the user clicks outside of it using jQuery? </title> <style> .container { height: 200px; width: 200px; background-color: green; border: 5px solid black; } </style> <script src= </script> </head> <body> <h1 style="color: green"> GeeksForGeeks </h1> <b> How to hide a div when the user clicks outside of it using jQuery? </b> <p>Click outside the green div to hide it</p> <div class="container" style="color:green"></div> <script type="text/javascript"> $(document).mouseup(function (e) { if ($(e.target).closest(".container").length === 0) { $(".container").hide(); } }); </script> </body> </html> |
Output:
Method 2: Checking the element if it contains the click target:
Example:
<!DOCTYPE html> <html> <head> <title> How to hide a div when the user clicks outside of it using jQuery? </title> <style> .container { height: 200px; width: 200px; background-color: green; border: 5px solid black; } </style> <script src= </script> </head> <body> <h1 style="color: green"> GeeksForGeeks </h1> <b> How to hide a div when the user clicks outside of it using jQuery? </b> <p>Click outside the green div to hide it</p> <div class="container" style="color:green"></div> <script type="text/javascript"> $(document).mouseup(function (e) { var container = $(".container"); if(!container.is(e.target) && container.has(e.target).length === 0) { container.hide(); } }); </script> </body> </html> |
