What Does Javascript Void 0 Mean Codeforgeek In short, javascript:void (0) is a handy javascript keyword that stops a link from trying to load a url or redirect. the void operator evaluates an expression and returns undefined, letting developers discard any unwanted return value. Javascript:void (0) is commonly used in html to create a link that doesn’t perform any action or navigate to a new page. when placed in the href attribute of an tag, it allows the link to execute javascript code without reloading or changing the current page.
What Does Javascript Void 0 Mean Codeforgeek We explain what javascript:void (0) means and how you can fix javascript:void (0) error. javascript:void (0) is a placeholder url to tell the user that an onclick event is tied. Usage of javascript:void(0) means that the author of the html is misusing the anchor element in place of the button element. anchor tags are often abused with the onclick event to create pseudo buttons by setting href to "#" or "javascript:void (0)" to prevent the page from refreshing. With void, it tells the browser not to return anything (or return undefined). another use case of links with the javascript:void(0) reference is that sometimes, a link may run some javascript code in the background, and navigating may be unnecessary. The void operator is often used merely to obtain the undefined primitive value, usually using void(0) (which is equivalent to void 0). in these cases, the global variable undefined can be used.

What does void (0) actually do in javascript? void (0) tells the browser to evaluate the number 0, ignore the result, and return undefined. in plain terms, it runs code that does nothing and makes sure nothing is returned or displayed. it’s like a silent placeholder that avoids side effects. The void(0) part of javascript basically tells the browser to “do nothing.” it’s often used in websites that rely on javascript for navigation or dynamic content. In javascript, javascript:void(0) is a common expression used within hyperlinks to prevent the default behavior of the link, such as reloading the page or navigating to a new page. Javascript void 0 prevents the browser from loading a new page (or refreshing the current page).
