Question

关于form表单传值时的判断

<form name="form1" method="post" action=".../search.php";">
<select name="mid" id="searchselect">
<option value="">全站搜索</option>
<option value="0">文章</option>
</select>
</form>
我想要的效果是 如果value的值为空时,action=".../search.php",如果value的值为0时则action=".../a/search",
请问这要怎么实现哈,谢谢各位大大了,

Answer 2

我测了可以

<script type="text/javascript">
function changeAction(obj){
alert(obj.value);
var val=obj.value;
if(val!='') document.form1.action='.../a/search';
else document.form1.action='.../search.php';
}
</script>
<form name="form1" method="post" action=".../search.php";">
<select id="searchselect" onchange="changeAction(this)">
<option value="">全站搜索</option>
<option value="0">文章</option>
</select>
</form>
