onclick事件隱藏和顯示使用javascript

Question

我有在單個頁面兩種形式，
我想隱藏類2所形成=「寄存器」形式的onclick 「FUNC（1）」並顯示類=「號「窗體，使用java腳本。
and onclick 「func（2）」 hide class =「sign」 form and shows class =「register」 form。

<form method="post" action="agent.php" id="register_form" class="register" style="display:block;" name="form1" >      
       <h2>Sign-up </h2> 
       <input type="text" id="name" name="agent_name" placeholder="Agent Name.."/> 
       <input type="text" id="mail" name="agent_email" placeholder="E-Mail.." /> 
       <input type="text" id="password" name="agent_password" placeholder="Password.." /> 
       <input type="text" id="number" name="agent_mobile" placeholder="Mobile...." /> 
       <br><br><br><br><br><br><br><br><br> 


        <select class="form-control sele" name="agent_state" id="country" for="u_state" style="background: rgb(235,235,235);" onChange="getCity('findcity.php?country='+this.value)"> 
         <option value="" selected class="below">Choose state from below...</option> 
          <?php 
           while($row = mysql_fetch_array($result)) 
           { 
            $State = $row['state']; 
            $StateID = $row['state_id'];           
            echo "<option value=". $StateID ." cna=".$State.">" . $State ."</option>"; 
           } 
          ?> 
        </select> 

       <br> 
       <div id="citydiv"> 
        <select class="form-control sele" name="agent_location" for="u_city" style="background: rgb(235,235,235);"> 
         <option value="" selected class="below">Choose Location from below...</option> 
        </select> 
       </div>

       <input type="submit" id="register2" value="Not A Member.... Register" onclick="func(2)"/>

Answer 1

嘗試隱藏和顯示，

function func(para) 
{ 
if(para==1) 
{ 
$(".sign").show(); 
$(".register").hide(); 
} 
else if(para==2) 
{ 
$(".sign").hide(); 
$(".register").show(); 
} 

}
