JQuery AJAX语法

我正在试图找到正确的语法，以便将变量传递给我的JQuery帖子

var id = empid;

$.ajax({
    type: "POST",
    url: "../Webservices/EmployeeService.asmx/GetEmployeeOrders",
    data: "{empid: empid}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(result) {
        alert(result.d);
    }

我不认为数据：价值是完全正确的。有人帮我纠正了吗

谢谢

可以是URL编码的字符串或对象：

data: {empid: empid},

或

文件说：

要发送到服务器的数据。如果尚未转换为字符串，则会将其转换为查询字符串。它被附加到GET请求的url。请参阅processData选项以防止此自动处理。对象必须是键/值对。如果value是一个数组，jQuery用相同的键序列化多个值，即{foo:[“bar1”，“bar2”]}变成“&foo=bar1&foo=bar2”

这应该对你有用

$.ajax({
    type: "POST",
    url: "../Webservices/EmployeeService.asmx/GetEmployeeOrders",
    data: {empid: empid},
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(result) {
        alert(result.d);
}

$（文档）.ready（函数（）{
$.ajax({
类型：“POST”，
url:“Webservices/EmployeeService.asmx/GetEmployeeOrders”，
数据：“{'EmployeeId'：'empid'}”，***这个怎么样：

var id = empid;

$.ajax({
    type: "POST",
    url: "../Webservices/EmployeeService.asmx/GetEmployeeOrders",
    data: "{empid: " + empid + "}",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function(result){
        alert(result.d);
        console.log(result);
    }
});

不是。你在传递一个字符串，你应该传递一个对象文本，例如

data: {"empid" : empid}

看到区别了吗？假设empid是一个具有某种值的变量，这应该可以正常工作。或者您也可以这样做

data: "empid="+empid

如果要向服务器发送JSON字符串

data: "{empid: " + empid + "}"

如果要发送查询字符串参数（？empid=123）

您可以使用以下命令

var id = empid;

$.ajax({
    type: "POST",
    url: "../Webservices/EmployeeService.asmx/GetEmployeeOrders",
    data: "var1=val1&var2=val2&var3=val3&var4=val4&var5=val5",
    contentType: "application/json; charset=utf-8",
    dataType: "json",
    success: function (result) {
        alert(result.d);
    }

虽然不能直接回答您的问题，但以下是我们的一个项目中用于jquery调用的常用函数方法


代理方法接受现有函数并返回具有特定上下文的新函数

语法

$(selector).proxy(function,context)
$(selector).proxy(context,name)  

代码

dpInvokeAsync: function (serviceRequest, input, requestType, successCallBack) {
        var url = BASE_URL + serviceRequest;
        $.ajax({
            type: requestType,
            url: url,
            async: true,
            data: input,
            dataType: 'json',
            success: $.proxy(successCallBack, this),
            error:  $.proxy(this.handleFailure, this)
        });
    }


   this.dpInvokeAsync('App/ShowParts', searchCriteria, 'Post',
                      function (result) { alert(result);}
                      );

完整的ajax语法

var data="abc";
       $.ajax({
            type: "GET",
            url: "XYZ",
            data: {
                "data":data,
            },
            dataType: "json",

            //if received a response from the server
            success: function( datas, textStatus, jqXHR) {

            },

            //If there was no resonse from the server
            error: function(jqXHR, textStatus, errorThrown){

            },

            //capture the request before it was sent to server
            beforeSend: function(jqXHR, settings){

            },

            //this is called after the response or error functions are finished
            //so that we can take some action
            complete: function(jqXHR, textStatus){

            }

        }); 

我正试图通过postman发送ajax请求。ajax请求正在发送数据类型：`json`和数据：{loginId:'appletest@somedomain.com，client:“698983”}。当我进入邮递员界面时，我试图以JSON的形式发送正文参数，并在标题中包含所有上述信息和内容类型：application/JSON，但失败了，返回500。有什么帮助吗？
