Ajax原生方法：
<script type="text/javascript">
function delStudent(studentid){
$.ajax({
url:"/project/studentRpc/"+studentid+"/deleteStudentById.json",
type:"get",
dataType: 'json',
success:function(data){
var isDeleted= data.content.successed;
alert(typeof isDeleted);
if(isDeleted==true){
alert("删除成功");
window.location.reload();
}
}
});
}
</script>
dataType:'json' 设置返回值类型
contentType:"application/x-www-form-urlencoded"(默认值)
contentType参考文章：

页面采用回调函数function(data) 处理后台返回的结果
a标签onclick事件触发
<a href ="javascript:void(0);" class="btn btn-default" id ="add" onclick = "return addproduct(${s.id});">加入秒杀</a>
前台
function addproduct(id){
var mprice=document.getElementById("mprice_"+id).value;
var number=document.getElementById("number_"+id).value;
var sid=document.getElementById("special.id").value;
if (mprice==""){
alert("请输入特价价格");
return false;
}else if (number==""){
alert("请输入特价数量 ");
return false;
}else {
//重点在这儿
$.get("${ctx}/special/addProduct.action?specialVo.quantity="+number+"&specialVo.memberPrice="+mprice+"&specialVo.id="+id+"&special.id="+sid,
function(data){
if(data=="true"){
alert("添加成功");
window.location.reload();
}
})
/* window.location.href="${ctx}/special/addProduct.action?specialVo.quantity="+number+"&specialVo.memberPrice="+mprice+"&specialVo.id="+id+"&special.id="+sid; */
}
}
后台
public void addProduct(){
PrintWriter out=null;
try {
System.out.println(specialVo.getQuantity());
System.out.println(specialVo.getMemberPrice());
System.out.println(specialVo.getId());
System.out.println(special.getId());
HttpServletResponse response=ServletActionContext.getResponse();
out=response.getWriter();
out.print(true);
out.flush();
out.close();
} catch (Exception e) {
e.printStackTrace();
out.flush();
out.close();
out.println(0);
}
}
struts配置action无需result
<action name="addProduct" class="specialAction" method="addProduct" > </action>
方法有两种,一是返回无类型,即void类型,二是返回Action.NONE(String类型)当是这两种类型的时候,struts2就不会对result进行主动处理了
即我们只需要在action方法中,处理ajax调用,而返回void或者"none"就行了
