读取行在网格中工作正常，但在更新和创建它时根本不起作用。它没有击中控制器。我已经提供了代码，请您查看以下代码的错误。

    The below json is return from the read webservice

 {"items":[{"id":1,"publisherName":"Srini","active":false},  {"id":2,"publisherName":"Ram","active":false}]}

Answer 1

将您的创建和更新定义为函数

create: function (options) {
   var newitem=[];
    newitem.push({
        id:options.data.id,
        publisherName:options.data.publisherName,
        active:false
     });
   $.ajax({
          url: BASE_URL + "admin/createPublisher.htm",
          dataType: "json",
          type: "POST"
          cache: false,
          data:{target:Json.stringify(newitem)},
          success: function (result) {
                options.success(result); // Make sure to Return a Json back from the Server
          },
          error: function (result) {
                options.error(result);
           }
         });
},
update: function (options) {
  // do as the create 
},

从您的服务器方法createPublisher返回Json Back

<强>更新像这样定义你的架构

schema: {
            model: {
                id: "id",
                fields: {
                    id: { editable: false, nullable: true },
                    publisherName: { type: "string", validation: { required: true } },
                    active: { type: "boolean"}
                }
            }
        },

Answer 2

您的DataSource选项中缺少schema.model.id。

schema: {
    model: {
        id: "id",
        fields: {
            ...

DataSource使用设置为id的任何字段来确定该项是否为“new”。如果将ID字段设置为默认值（未定义或0），则将其发送到要创建的服务器。如果没有schema.model.is设置，它基本上会禁用创建。
