js form action动态修改方法

一般比较简单的就是
document.formName.action="/dddd.do?ddd="+str
document.formName.submit();

写成函数式的调用就是

<script language="JavaScript" > 
function checkaction(v){ 
if(v==0){ 
document.dbform.action="index.php?admin_db-repair"; 
}else{ 
document.dbform.action="index.php?admin_db-optimize"; 
} 
dbform.submit(); 
} 
</script> 
<form action="" method="post" name="dbform"> 
<input type="submit" class="btn" value="{lang dbStartOptimize}" name="opsubmit" onclick="checkaction(1);" /> 
<input type="submit" class="btn" value="{lang dbStartFix}" name="resubmit" onclick="checkaction(0);" /> 
</form>
