在JSP中一个页面如何获取另一个页面的Button按钮中的Value值?

Answer 1

a.jsp有个按钮
<input type="button" id="sub" value="提交“ onclick="test()" />

function test()
{
var name = document.getElementById("sub").value;
window.location.href = "b.jsp?btnname="+name;
}

b.jsp获取

var btnname = request.getParameter("btnname");

if(btnname==null)
{
btnname = "";

}
