stop javascript executing when catch error

Question

I need a function that stop execute javascript when catch error. For example as follow:

function AA()
{
  try{
    executeScript();
  }catch(e){
    //stop execute javascript
  }
}

function executeScript()
{
   throw 'error';
}
function BB()
{
  //some script
}
AA();
BB(); //don't execute when error happening

Has anybody know how to do it? Thanks for help.

Answer 1

I think if you use a return it should be possible :)

function AA()
{
  try{
  }catch(e){
    //stop execute javascript
    return;
  }
  BB(); //don't execute when error happening
}

function BB()
{
  //some script
}

return like that will just return undefined. You can return something more specific like a string or anything else to be able to have a convenient behaviour when you get this early return.

Answer 2

There are two ways,

1. Add return statement

    function AA()
    {
      try{
      }catch(e){
        return;
      }
      BB();  
    }
   
    function BB(){   
    }
   

2. If you want to return from in code before catch calls you can add throw

   function AA() {           
       try{
          javascript_abort();
        }catch(e){
           return;
        }
        BB();  
       }
   
   
    function BB(){   
            }
   
        function javascript_abort(){
           throw new Error('This is not an error. This is just to abort javascript');
        }
