Question

我在jsp中创建一个页面。基本上将我的html设计转换为jsp页面。使用Apache tomcat作为服务器。

我的问题是我正在尝试通过表单提交上的Ajax调用加载结果页面。我收到“错误：Precondtion Failed”错误。

任何人都可以解决此错误。

我的代码如下

$(document).ready(function(){
$("form").submit(function(e) { 
    alert("hello");
e.preventDefault();
$.ajax({

url: "aspSearchResultPage.html",
success: function()
{
$("#information").load("aspSearchResultPage.html");

return false;
});

@Priya我希望你使用struts。通过操作发送请求并将请求转发到您需要加载的jsp页面。返回与响应数据（此处）相同的jsp页面，并使用该数据填充div。为您的目的找到下面的代码片段。您需要根据需要修改代码。

$.ajax({
    url : "yourAction.do?method=yourMethod",
    type : "POST",
    async : false,
    success : function(data) {
        $("#information").html(data);
    }
});

如果这有帮助，请告诉我。
