Grails中g form表单添加id

<g:form>标签中id项确实不支持此项功能，若需要在生成的form中添加id项，可以使用name项，这将在生成的页面中生成相同的name和id两个元素

<g:form controller="game" action="list" name="gameForm">  
  <label for="name">Username</label>  
  <input type="text" name="name" id="name"/>  
  <label for="psw">Username</label>  
  <input type="password" name="psw" id="psw"/>  
</g:form> 

<form action="game/list" id="gameForm" name="gameForm">  
  <label for="name">Username</label>  
  <input type="text" name="name" id="name"/>  
  <label for="psw">Username</label>  
  <input type="password" name="psw" id="psw"/>  
</form>
