Upgrade from 3.6.4 to 3.6.5

You should read this upgrade notes when you use JSON response from the server.
These notes are valid when you upgrade from any other version of jqGrid.

With version 3.6.5 we switch from ajax complete to ajax success event.
With this switch we directly use the jQuery parsing of JSON data. As of version 1.4.x of jQuery this parsing is strict. More information can be found here
This will reflect in certain systems not to display the data.

What you need to know if the data is not displayed when you upgrade from 3.6.4 to 3.6.5 version

Valid JSON response

Your json response should be correct json formatted string. This mean that if your response look like this:

{ 
  total: "xxx", 
  page: "yyy", 
  records: "zzz",
  rows : [
    {id:"1", cell:["cell11", "cell12", "cell13"]},
    {id:"2", cell:["cell21", "cell22", "cell23"]},
      ...
  ]
}

This will not work.

In order to display the data in the grid, you should properly define the json response - i.e

{ 
  "total": "xxx", 
  "page": "yyy", 
  "records": "zzz",
  "rows" : [
    {"id" :"1", "cell":["cell11", "cell12", "cell13"]},
    {"id" :"2", "cell":["cell21", "cell22", "cell23"]},
      ...
  ]
}

As can be seen every property should be quoted.

The "d" Property

Switching from ajax complete to ajax success event causes to skip the jqGrid parse function, which detect automatically the so named “d” property from the response (used in certain systems).

In order to solve the problem the jsonReader should be changed so that it can interpret this property correct.
If the default jsonReader is :

jQuery("#gridid").jqGrid({
...
   jsonReader : {
     root: "rows",
     page: "page",
     total: "total",
     records: "records",
     repeatitems: true,
     cell: "cell",
     id: "id",
     userdata: "userdata",
     subgrid: {root:"rows", 
        repeatitems: true, 
       cell:"cell"
     }
   },
...
});


It should be changed to

jQuery("#gridid").jqGrid({
...
   jsonReader : {
     root: "d.rows",
     page: "d.page",
     total: "d.total",
     records: "d.records",
     repeatitems: true,
     cell: "cell",
     id: "id",
     userdata: "userdata",
     subgrid: {root:"d.rows", 
        repeatitems: true, 
       cell:"cell"
     }
   },
...
});

Note that the cell property should not be changed

loadComplete changes

As of the documentation to the loadComplete event we pass as parameter the request from the response. In most cases to use the request before version 3.6.5 you will need to use the responseText property.
After this change the “response” passed to this event is actually the data from the server converted automatically from jQuery according to the datatype parameter.

By example let suppose that you use json datatype. Before 3.6.5 in order to use the response as object you maybe do the following:

jQuery("#gridid").jqGrid({
...
datatype : "json",
loadComplete : function (request) {
// to convert the request using JSON.parse to JavaScrip object you do maybe this:
var myrequest  = JSON.parse(request.responseText);
....
},
...
});

After 3.6.4 you should remove JSON.parse -i.e

jQuery("#gridid").jqGrid({
...
datatype : "json",
loadComplete : function (request) {
// no need to use JSON.parse:
var myrequest  = request;
....
},
...
});
