如何在點擊提交後讓我的HTML頁面保持原樣？

Question

我想在用戶輸入後提交頁面不會改變。

 <script src="doAction.js" language="Javascript" type="text/javascript"></script> 
    <form name = "ex4Param" id="ex4Param" method="post" onsubmit="doAction();" > 
     <fieldset> 
      <legend>Input section</legend> 
     Query Sequence:<br/> 
     <td><textarea rows="5" cols="84" id="enhancers" name="charSequence"></textarea></td> 
      <form/> 

Answer 1

onsubmit="return doAction();"

在doAction： return false
