javascript - Unexpected submit on "submit" button click -

If I activate the button (with the tab button), and then Enter , the keyboard handler will set fire, and click on the button will generate the event. But the OnClick will submit and the handler will not fire it will just silently post the form. Why?

  & lt; Script src = "../js/jquery.js" type = "text / javascript" & gt; & Lt; / Script & gt; & Lt; Script type = "application / javascript" & gt; $ () Ready (function () {$ ("# F1") .press (function (event) {if (event.keyCode == 13) {var currentInputId = $ (event) [0]. Target.id; Var currentInput = $ ('#' + Current input id); Current input.Click (); Return back;}}); $ ("#F1"). Submit (function () {Alert ("huy"}}}) & Lt; / script & gt; form name = "f1" id = "f1" method = "post" & gt; & gt; input type = "text" & gt; & gt; input type = "submit "Onclick =" return false; "id =" presented ">     
 
 
 rewritten from scratch  
 
  
  
   handler Click the call  button   
 button  onclick  return  false   
 event handling stop (Form not submitted)   
 If I delete  onclick = "return false"; , then  
 
  keypress  handler runs and click on call   button   Form  without   submit  handler is called   
 Some more tests indicate that  submit  Handler is not being called * because you come back from  false  to  keypress  handler.  
 Then, the problem to resolve:  
 
 button  onclick = "return false";  Remove  
 Remove  false false   questions  handler   
 will display this alert and then submit the form Will submit as you expect it.
