Javascript停止执行中止或退出

Question

if(a.value==1 && b.value==2)
{
    try{callFunc()  }catch(e) {} 
}
frm.submit();

在里面function callFunc()，我必须写什么才能完全停止执行？它不应该执行frm.submit();

function callFunc()
{
    //stop execution here -- ensure it won't execute fm.submit()
}

更好的一个是

function Abort()
{
   throw new Error('This is not an error. This is just to abort javascript');
}

比任何地方叫这个

try
{
    for(var i=0;i<10;i++)
    {
         if(i==5)Abort();
    }
} catch(e){}

为你

function callFunc()  
{      
    //stop execution here 
    Abort();

    } 

//code from where you are going to call

try
{
  if(a.value==1 && b.value==2)    
  {        
   callFunc()   
  }    
  frm.submit(); 
}
catch(e) {}
