Question

Just want to confirm something here. Is it possible to use jqGrid’s userData with a javascript type directly (as opposed to using an object with field(s))?

If I modify the example in the jqGrid doc, I would like to return this json to jqGrid:

{ 
  total: "xxx", 
  page: "yyy", 
  records: "zzz", 
  userdata: 0, 
  rows : [ 
    {id:"1", cell:["cell11", "cell12", "cell13"]}, 
    {id:"2", cell:["cell21", "cell22", "cell23"]}, 
    ... 
  ] 
}

and have jQuery("grid_id").jqGrid('getGridParam', 'userData') return 0.

Presently it seems to return an empty object { } instead.

I use jqGrid 4.4.1.

userdata part of the JSON input for jqGrid should be object. If you need to return scalar inside of userdata you should use something like

"userdata": { mycounter: 0 }

and then use

var userdata = $("#grid_id").jqGrid("getGridParam", "userData");
if (userdata) {
    alert(userdata.mycounter);
}
