Asp.net 向WebMethod发送字符串值

这是我的WebMethod

function EmpCode(empCode) {
    var queryString = "";
    var hasQuerystring = document.URL.indexOf('?');
    if (hasQuerystring != -1) {
        queryString = document.URL.substring(hasQuerystring + 1, document.URL.length);
        if (queryString == 'id=1') {
            $.ajax({
                type: "POST",
                url: "EmployeeBasicInfo.aspx/CheckEmpCode",
                data: "{'empCode':" + empCode + "}",// Sending empCode which is a string
                contentType: "application/json; charset=utf-8",
                dataType: "json",
                success: function (msg) {
                    var errorMsg = (msg.d);
                    if (errorMsg != 'NA') {
                        alert(errorMsg);
                    }
                }
            });
        }
    }
}

当我将EMP代码作为'11479'0r从Ajax发送任何整数时，web方法正在调用。当我将empcode作为C1026或任何带有字符的字符串发送时，则不会调用webmethod

请建议我如何传递具有字符串值的empCode。

在empCode周围加引号。当前您正在发送：

[WebMethod]
public static  string CheckEmpCode(string empCode)
    {
    string empCod = "";
    EmployeeFactory empFactory = new EmployeeFactory();
    empCod = empFactory.CheckCode(empCode);
    return empCod;
}

您需要发送：

data: {'empCode': C1026}

请重新格式化你的问题。非常感谢罗伯特。这对我很有帮助罗伯特对我很有帮助

data: {'empCode': 'C1026'}
