1.button的type设置为button 而不用submit，并添加onclick方法调用js函数

<input type=”button” name=”confirmAlter” value=”确认修改” οnclick=”changeInfo(form1.code,form1.name,form1.detail,form1.count)”/>

2.传到js函数中，然后提交表单到servlet并传递参数

<script language=”javascript”>

function changeInfo(code,name,detail,count){


var string1 = code.value;

var string2 = name.value;

var string3 = detail.value;

var number = count.value;

//alert(“hello word!”);

document.getElementById(‘form1’).action=”workServlet?action=alterInfo&code=”+string1+”&name=”+string2+”&detail=”+string3+”&count=”+number;

document.getElementById(“form1”).submit();


}

</script>

3.在servlet中调用request.getParameter()方法即可获取参数
