[英]jqGrid - loading values from JSON
I have a jqGrid
working OK using the local
datatype, but I now want the values to be loaded via json
but having trouble changing it. 我有一个jqGrid
使用local
数据类型jqGrid
正常工作,但现在我希望通过json
加载值,但无法更改它。
This is my jqGrid
code 这是我的jqGrid
代码
jQuery("#grid").jqGrid({
datatype: "json",
url: "/controller/getItems?id=2",
width: 1405,
colNames: ['id', 'surname'],
colModel: [
{ name: 'id', index: 'id', editable: false, hidden: false, hidedlg: true },
{ name: 'surname', index: 'surname', editable: true }
],
onSelectRow: function (id, status, e) {
...
},
editurl: url,
...
So the method to get the JSON is sucessfully fired. 因此,成功触发了获取JSON的方法。
[HttpGet]
public ActionResult getItems(string id)
{
List<model> items = method.getItems(id);
string jsonText = new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(items);
return Json(jsonText, JsonRequestBehavior.AllowGet);
}
The column names in the JSON
do match the colModel
names JSON
的列名称与colModel
名称匹配
Example of the json
being returned - what the object jsonText
above contains 返回json
示例-上面的jsonText
对象包含的内容
[{"id":434,"surname":"Woods"},
{"id":435,"surname":"Adams"}]
Is there anything I have done wrong or am missing? 我做错了什么或想念什么吗?
Thanks 谢谢
I suppose that the error in in using of System.Web.Script.Serialization.JavaScriptSerializer().Serialize
. 我想在使用System.Web.Script.Serialization.JavaScriptSerializer().Serialize
出现错误。 You need just return Json(items, JsonRequestBehavior.AllowGet);
您只需要返回Json(items, JsonRequestBehavior.AllowGet);
. 。 Additionally you can remove the column id
from the colModel
. 另外,您可以从colModel
删除列id
。 The id
value will be still read and assigned as the value of id
attribute of the rows ( id
of <tr>
elements of the grid) known as rowid. 仍将读取id
值并将其分配为称为rowid的行的id
属性值(网格的<tr>
元素的id
)。 You should add loadonce: true
option to the grid because you don't implemented paging of data on the server side and to add gridview: true
(if you not already use it) to have better performance and autoencode: true
to interpret input data as texts instead of HTML fragments. 您应该向网格中添加loadonce: true
选项,因为您没有在服务器端实现数据分页,而是添加了gridview: true
(如果尚未使用)以提高性能,并自动autoencode: true
以将输入数据解释为文本而不是HTML片段。
UPDATED : In case of usage old version of jqGrid one have to include jsonReader
parameter which corresponds the format of input data: 更新 :如果使用旧版本的jqGrid,则必须包含jsonReader
参数,该参数对应于输入数据的格式:
jsonReader: {
repeatitems: false,
root: function (obj) { return obj; }
}
One should still use loadonce: true
option additionally. 仍然应该另外使用loadonce: true
选项。
