return false on JS confirm

[Sandro87]

hi how can I return false so that the page wont go on the top when someone doesn't confirm a JS confirm?

  function confirm_tip(url, message){
  
   if(confirm(message)){
   window.location= url;
  }
  
  }

function confirm_tip(url, message){

 if(confirm(message)){
 window.location= url;
}
else{
return false;
}

}

this doesn't work

Check how confirm_tip is being called, if it is onclick for example you will need

onclick="return confirm_tip ... "

Apparently we lost some posts this weekend. You want to return false in any case . . . remove the else. A more efficient way would be to 1) externally attach the behavior, and 2) use a valid URL. This would allow you to use the href attribute, it would still work for Javascript disabled visitors, you would un-bloat your link code and only need an ID, and if those three aren't enough, would allow search engines to follow your link. :-)

window.onload = function() { 
if (document.getElementById('some-link')) { 
 document.getElementById('some-link').onclick=function() { 
 return confirm_tip(this.href,'Navigate to '+this.href+'?'); 
 }; 
 } 
}; 
function confirm_tip(url, message){ 
if(confirm(message)){ 
window.location=url; 
} 
return false; 
} 

.....

<p><a href="somepage.html" id="some-link">Some Page</a></p>

You want to return false in all cases, but have to "accept" it at the link level. Usage of the false return *and* an actual URL instead of # will allow the link to still work without Javascript, appreciated by both those who have it disabled *and* search engines. :-) A cleaner way is to externally attach the behavior:

window.onload = function() { 
if (document.getElementById('some-link')) { 
 document.getElementById('some-link').onclick=function() { 
  return confirm_tip(this.href,'Navigate to '+this.href+'?'); 
 }; 
 } 
}; 
function confirm_tip(url, message){ 
if(confirm(message)){ 
window.location=url; 
} 
return false; 
} 

<p><a href="somepage.html" id="some-link">Some Page</a></p>
