Show/hide 'div' using JavaScript
How to show or hide an element:
In order to show or hide an element, manipulate the element's style property. In most cases, you probably just want to change the element's display property:
element.style.display = 'none'; // Hideelement.style.display = 'block'; // Showelement.style.display = 'inline'; // Showelement.style.display = 'inline-block'; // ShowAlternatively, if you would still like the element to occupy space (like if you were to hide a table cell), you could change the element's visibility property instead:
element.style.visibility = 'hidden'; // Hideelement.style.visibility = 'visible'; // ShowHiding a collection of elements:
If you want to hide a collection of elements, just iterate over each element and change the element's display to none:
function hide (elements) { elements = elements.length ? elements : [elements]; for (var index = 0; index < elements.length; index++) { elements[index].style.display = 'none'; }}// Usage:hide(document.querySelectorAll('.target'));hide(document.querySelector('.target'));hide(document.getElementById('target'));Showing a collection of elements:
Most of the time, you will probably just be toggling between display: none and display: block, which means that the following may be sufficient when showing a collection of elements.
You can optionally specify the desired display as the second argument if you don't want it to default to block.
function show (elements, specifiedDisplay) { elements = elements.length ? elements : [elements]; for (var index = 0; index < elements.length; index++) { elements[index].style.display = specifiedDisplay || 'block'; }}// Usage:var elements = document.querySelectorAll('.target');show(elements);show(elements, 'inline-block'); // The second param allows you to specify a display valueAlternatively, a better approach for showing the element(s) would be to merely remove the inline display styling in order to revert it back to its initial state. Then check the computed display style of the element in order to determine whether it is being hidden by a cascaded rule. If so, then show the element.
function show (elements, specifiedDisplay) { var computedDisplay, element, index; elements = elements.length ? elements : [elements]; for (index = 0; index < elements.length; index++) { element = elements[index]; // Remove the element's inline display styling element.style.display = ''; computedDisplay = window.getComputedStyle(element, null).getPropertyValue('display'); if (computedDisplay === 'none') { element.style.display = specifiedDisplay || 'block'; } }}(If you want to take it a step further, you could even mimic what jQuery does and determine the element's default browser styling by appending the element to a blank iframe (without a conflicting stylesheet) and then retrieve the computed styling. In doing so, you will know the true initial display property value of the element and you won't have to hardcode a value in order to get the desired results.)
Toggling the display:
Similarly, if you would like to toggle the display of an element or collection of elements, you could simply iterate over each element and determine whether it is visible by checking the computed value of the display property. If it's visible, set the display to none, otherwise remove the inline display styling, and if it's still hidden, set the display to the specified value or the hardcoded default, block.
function toggle (elements, specifiedDisplay) { var element, index; elements = elements.length ? elements : [elements]; for (index = 0; index < elements.length; index++) { element = elements[index]; if (isElementHidden(element)) { element.style.display = ''; // If the element is still hidden after removing the inline display if (isElementHidden(element)) { element.style.display = specifiedDisplay || 'block'; } } else { element.style.display = 'none'; } } function isElementHidden (element) { return window.getComputedStyle(element, null).getPropertyValue('display') === 'none'; }}// Usage:document.getElementById('toggle-button').addEventListener('click', function () { toggle(document.querySelectorAll('.target'));});
You can also use the jQuery JavaScript framework:
To Hide Div Block
$(".divIDClass").hide();To show Div Block
$(".divIDClass").show();
You can simply manipulate the style of the div in question...
document.getElementById('target').style.display = 'none';
