javascript - form not getting submitted on button click -

i trying submit form on button click want user confirm whether sure or not. have mutiple submit button on form , want pop-up in case of delete. when make type of button submit. form gets submitted twice if confirm else gets submitted once (i don't want submitted in case).

i have multiple form on page. that's why trying submit form getting parent node , not using getelementbyid.

javascript function

function deleteevent(btn){       var confirmed=confirm('do want delete event?');       if(confirmed){           var f = btn.parentnode;           f.submit();           }       else{           return false;           }     } 

html code

<form action="#" method="post"> <input type="button" name="delete" value="delete" onclick ="deleteevent(this)"> </form> 

thanks.

working solution:

<input type="submit" name="delete" value="delete" onclick ="return confirm('do want delete event?');"> 

try this

use onclick="return deleteevent(this);" if button type submit

<input type="submit" name="delete" value="delete" onclick="return deleteevent(this);">
