Javascript 将输入文本值传递给ajax调用

Javascript 将输入文本值传递给ajax调用,javascript,jquery,ajax,Javascript,Jquery,Ajax,我必须通过jQueryAjax将输入文本中输入的字符串传递给服务器方法调用。但它没有通过。谁能告诉我我做错了什么吗。代码如下: $.ajaxSetup({ cache: false timeout: 1000000}); function concatObject(obj) { strArray = []; //new Array for (prop in obj) { strArray.push(prop + " value :" + obj[prop])

上面是js文件,下面是其aspx文件:

员工的NTID:




您需要从引号中提取
数据:“{'ntid':$('#Eid').val()”

编辑看一看,您的问题中的代码正确地尝试发送ajax请求

编辑2在这里:

$.ajax({
    type: "POST",
    url: "Testing.aspx/SendMessage",
    data: { ntid: $('#Eid').val()}, // Notice the lack of quotes
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(result) {
        console.log(result.d);
        resultData = eval("(" + result.d + ")");
        //$("#rawResponse").html(result.d);
    },
    error: function(result) {
        alert("jQuery Error:" + result.statusText);
    }
});

数据格式不正确。您可以在ajax()函数之外创建json对象,以便于管理

    var keyvalue = {
      ntid : $('#Eid').val()
    };
    $.ajax({
            type: "POST",
            url: "Testing.aspx/SendMessage",
            //data: "{'ntid':'stephen.gilroy1'}",       //working
            data: keyvalue,
            contentType: "application/json; charset=utf-8",
            dataType: "json",
            success: function(result) {
                alert(result.d);
                resultData = eval("(" + result.d + ")");
                $("#rawResponse").html(result.d);
                //$("#response").html(resultData.sn);
            },
            error: function(result) {
                alert("jQuery Error:" + result.statusText);
            }
    });
谢谢大家! 它现在可以通过使用以下线路工作:

data: "{'ntid': '"+$('#Eid').val()+"'}",

谢谢,但问题仍然存在here@amby:什么具体不起作用。正如我提供的链接所示,AJAX调用被正确触发。我知道我的代码成功地发送了AJAX请求,因为我尝试只发送简单的字符串数据:“{'ntid':'stephen.gilloy1'}”,它工作得很好,但当我尝试发送输入文本框字符串时,它会给出jquery:internalservererror@amby:你看过我提供的链接了吗?您还应该更新问题中的代码,以反映我和Jonathan Mayhak关于使用对象而不是字符串作为数据参数的评论?我在那里看不到您的代码。jquery内部服务器错误,但问题是当我尝试发送这样的数据时:“{'ntid':'stepqwe1'}”,它可以工作,但当尝试发送输入文本值时,它给出了上述错误
