SweetAlert Calling code after clicking "Cancel" button

You're passing too many parameters to the swal constructor. It needs only two:

swal(options, callback)

• options: Attributes to design the alert
• callback: The callback function to manage the events

When you use a simple confirm, the callback receive only one parameter that indicates the user choice:

• true: Confirm
• false: Cancel

With inputbox you will receive the user's input string as parameter.

When you merge together inputbox and confirm, you could receive:

• the input string value: When the user press Confirm
• false: When user press Cancel

So, you have to use the Strict Equality Comparison in order to know if user pressed cancel or have inserted the string false in the input box.

Please see the following simple example:

swal({
  title: "Are you sure?",
  text: "Press CANCEL, please!",
  type: "input",
  showCancelButton: true,
  confirmButtonColor: "#DD6B55",
  confirmButtonText: "CONFIRM",
  cancelButtonText: "CANCEL",
  closeOnConfirm: false,
  closeOnCancel: false
},
function(inputValue){
  //Use the "Strict Equality Comparison" to accept the user's input "false" as string)
  if (inputValue===false) {
    swal("Well done!");
    console.log("Do here everything you want");
  } else {
    swal("Oh no...","press CANCEL please!");
    console.log("The user says: ", inputValue);
  }
});

I hope it helps you, bye.

you can also use the implementation of promises using .then

I give you an example, this would be executed just after pressing the button

swal( 'Error!',valido.msj,'error').then((e)=>{
  if( valido.msj=="Enlace de botón No Válido" ){
     document.getElementById('link_btn_barra').focus();
  } 
});
