不报异常，浏览器错误面板没有错，就是进不了Action不知道为什么，页面两种ajax访问都不行。求高手指点
$(function(){
$("#name").bind('onblur', function(){
var nv = $("#name").val();
if(confirm("确定？")){
$.ajax({
url : "../web/check.action",
data : {name : nv},
type : "post",
dataType : "json",
success : function(data) {
//包数据解析为json 格式
if(data.ok){....}
}
});
}
});
});如果../web/check.action不行的。。
那就利用jsp页面上的路径
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";<%=basePath%>/web/check.action
