如何在ajax调用中传递值？

Question

在我的以下代码中，更新功能在 ajax 中不起作用..如何解决这个问题，..

在我的代码编辑方法中运行良好..

例如：在此代码中，值传递var name = row.find(".ContactPersonName").find("span").html();

但是在更新值的时候没有传入它

data: '{hospitalID: ' + HospitalID + ',contactID: ' + ContactID + ', DepartmentID: "' + DepartmentID + '",DesignationID: "' + DesignationID + '",ContactPersonAddress:"' + ContactPersonAddress + '",Phone:"' + Phone + '",AadhaarCardNo:"' + AadhaarCardNo + '", name: "' + name + '", mobile: "' + mobile + '" }',

Answer 1

您的更新医院联系方式为get方式。因此，您可以将参数作为查询字符串传递。更新您的 AJAX 方法，如下所示。

 $.ajax({
          type: "Get",
          url: pageUrl + '/UpdateHospitalContact?hospitalID=' + HospitalID + '&contactID=' + ContactID + '&DepartmentID=' + DepartmentID + '&DesignationID=' + DesignationID + '&ContactPersonAddress=' + ContactPersonAddress + '&Phone=' + Phone + '&AadhaarCardNo=' + AadhaarCardNo + '&name=' + name + '&mobile=' + mobile,
          contentType: "application/json; charset=utf-8",
          dataType: "json"
       });

Answer 2

现在运行良好

$.ajax({
         type: "POST",
         url: pageUrl + '/UpdateHospitalContact',
         data: '{"ContactId": "' + ContactID + '","DepartmentId": "' + DepartmentID + '","DesignationId": "' + DesignationID + '","Name": "' + name + '","address": "' + Address + '","mobile": "' + mobile + '","phone": "' + Phone + '","aadhaarCardNo": "' + AadhaarCardNo + '"}',
         contentType: "application/json; charset=utf-8",
         dataType: "json"
            });
