点击按钮调用函数并且改变action的路径

<form action=""  name="form1" id="form1">

<input type="submit" onclick="sub1()" name="" value="" />

<input  type="submit" onclick="sub2()"  name="" value=""  />

</form>

<script type="text/javascript">

function sub1(){

document.getElementById('form1').action="/admin.php?s=aaa";

}

function sub2(){

document.getElementById('form1').action="/form.php?s=bbb";

//若需提交表单（如导出）

document.getElementById('form1').submit();

}

</script>
