jqGrid无法加载，并且错误指出其无效的xml，但是数据是JSON [英] jqGrid does not load and with error that its invalid xml, however data is JSON

问题描述

我在加载jqGrid时出现如下错误:

I get onloading the jqGrid a error as follow:

加载错误:错误:无效的XML:{"d":[{"id":1，"name":医疗 1，" city:" Kiev，" instituteTypeId:0}，{" id:2，" name:" Medical 2，" city:" Kherson，" instituteTypeId:0}]}

load error: Error: Invalid XML: {"d":[{"id":1,"name":"Medical 1","city":"Kiev","instituteTypeId":0},{"id":2,"name":"Medical 2","city":"Kherson","instituteTypeId":0}]}

但是我使用JSON，oleg建议我打开新威胁.

however I use JSON, oleg advised me to open new threat.

jquery代码是:

The jquery code is:

  mtype: 'POST',
  contentType: "application/json",
  url: "dataServices/objects.asmx/InvokeData",
  ajaxGridOptions: {
      contentType: 'application/json; charset=utf-8'
  },
     postData: JSON.stringify({q: "med&1"}),
                loadonce: true,
                dataType: 'json',
                jsonReader: {
                    root: function (obj) {
                        alert(obj.d);
                        return obj.d;
                    },
                    page: "",
                    total: "",
                    records: function (obj) {
                        return obj.d.length;
                    },
                },
                gridview: true,
                loadError: function (xhr, status, error) {
                    alert('load error: ' + error);
                },

没有dataType = xml或任何定义的内容....

There is no dataType= xml or anything defined....

推荐答案

您使用的是dataType: 'json'，这是错误的. jqGrid具有选项datatype，没有选项dataType.因此，您应该使用dataType: 'json'.未知选项dataType将被忽略，而将使用默认选项dataType: 'xml'.

You use dataType: 'json' which is wrong. jqGrid has the option datatype and no dataType. So you should use dataType: 'json'. Unknown option dataType will be just ignored and default option dataType: 'xml' will be used.

另外，我认为您应该只使用jsonReader: { root: "d" }.

Additionally I think you should use just jsonReader: { root: "d" }.

演示应该接近您的需求.所以你应该做类似的事情

The demo should be close to what you need. So you should do something like

$("#list").jqGrid({
    mtype: 'POST',
    url: "dataServices/objects.asmx/InvokeData",
    datatype: "json",
    ajaxGridOptions: {
        contentType: "application/json; charset=utf-8"
    },
    postData: JSON.stringify({q: "med&1"}),
    loadonce: true,
    jsonReader: { root: "d" }
    ...
});
