如何将数据传递给AJAX调用 [英] How to pass data to AJAX call

问题描述

有谁能告诉我如何将数据传递给进行AJAX调用的jsp？这就是我想要的：

Can anyone tell me how to pass data to the jsp making the AJAX call ? This is what I am trying:

这是我的AJAX电话：

Here is my AJAX call:

     $.get("gridedit.jsp", { before: "row", time: "2pm" })
               .done(function(data) {
                 alert("Data Loaded: " + data);
               });

这是我的gridedit.jsp

here is my gridedit.jsp

    <% String b=request.getParameter("before");

    if(b.equalsIgnoreCase("row"))
     {
System.out.println("ROW ROW ROW your boat");
        out.println("bummer");
    } %>

我想将gridedit.jsp返回的值存储到javascript变量中。我该怎么做？

i want to store the value returned from gridedit.jsp into a javascript variable. How should I do this ?

    $.ajax({
                url: "gridedit.jsp",

                async: true,
                cache: false,
                type:"GET",
                data: {
                    before:'row',
                      },
                      error: function(msg) { alert(msg); },
                      complete: function (xhr, status) { alert('complete: '+status); }

            });

错误;

所以我在这里尝试

      $.ajax({
                url: "gridedit.jsp",
                //dataType: "json",
                async: true,
                cache: false,
                type:"GET",
                data: {
                    before:'row'
                      },
                      error: function( jqXHR, textStatus, errorThrown ) { alert(jqXHR);
                      alert(textStatus);
                      alert(errorThrown);},
                      complete: function (xhr, status) { 
                          alert('jqXHR:'+xhr);
                          alert('complete: '+status); }

            });

我按顺序收到以下提醒：

i get the following alerts in order:

jqXHR：
[object] [object]

jqXHR: [object][object]

testStatus：

testStatus:

      parseerror

errorthrown：

errorthrown:

      Unexpected end of input

任何人都可以帮助我解决这个？我的gridedit.jsp执行此操作 - >

推荐答案

尝试第二个：

我有一个看起来像这样的ajax请求：

I have an ajax request that looks like this:

$.ajax({
    url: "/someplace",
    dataType: "json",
    async: true,
    cache: false,
    data: {
        number0: 0,
        key: littleKey
    },
    success: function(data, status)
    {
        alert(data);
    }
});

并按预期工作。

你可以用指定get：使用其他选项输入GET。

也许尝试让你的.jsp打印一些数据，不管是什么，还打印它接收的数据。

Maybe try having your .jsp print some data no matter what, and also print what data it is receiving.
