Question

it make javascript delete one row which id = 1455174

but ,why is void(0)? what's mean ?

Answer 1

To prevent the page reloading upon a single click, we can use JavaScript:void(0); within the anchor link.

Answer 2

stops the link activating. Best to avoid the javascript protocol if possible better to use the click event.

Answer 3

Its to prevent the default behaviour of the link from being activated, namely redirecting the browser to a new page. Your example though shows poor JavaScript practice - you should look into coding things unobtrusively and into the use of progressive enhancement
