I have a functionality so that when you want to delete a Patient by clicking on delete, ask if you really want to delete it or not.

It shows the question, but when I give it to cancel it erases it to me equally and if I give it to accept it happens the same.

The onClick to call the JavaScript function is within a <tr> , that <tr> main also has a onClick , I do not know if that can cause any conflict.

This is the code used:

JS:

function irAWeb(event) {
  if (confirm("¿Quieres ir a la página del Mensajeitor?") == false) {
    event.stopPropagation();
    event.preventDefault();
    return false;
  }
  return true;
}

HTML:

<a onclick="return irAWeb();" href='pagines/esborrar.asp?id=<%=rs("Numero")%>&que=<%=nomfitxer%>'> <img src="images/delete.gif" border="0" alt="Borrar" /> </a>

javascript html

I would not know how to tell you why that happens, I'll always pass by and I'll solve it by adding a more code line, where I get the result of confirm

function irAWeb(event) {
  $bool=confirm("¿Quieres ir a la página del Mensajeitor?");
  if($bool){
  alert("marcaste OK");
  }else{
  alert("marcaste Cancelar");
  }
  
}

<a onclick="return irAWeb();" href='#'> <img src="images/delete.gif" border="0" alt="Borrar" /> </a>

I know that it does not seem to have any change since it would have to be the same, but in this way it works correctly.

The problem must be that you forgot to pass event when calling the function irAWeb in onclick .

Solution:

Modify the HTML in the following way:

<a onclick="return irAWeb(event);" href='pagines/esborrar.asp?id=<%=rs("Numero")%>&que=<%=nomfitxer%>'>
  <img src="images/delete.gif" border="0" alt="Borrar" />
</a>
