Change the value of data field in JSON source

[rlisarioMember]

Dear,
This is the source of my grid:

var source =
{
datatype: “json”,
datafields:
[
{ name: ‘Model’ },
{ name: ‘Description’ },
{ name: ‘Year’, type: ‘int’ }
],
id: ‘id’,
url: ‘machines_load.php’,
data: { Tipology: 1 },
root: ‘data’
};

In this way, machines_load.php page can be retrive from database only machine of Tipology=1

My question is:

How can I change the value of Tipology runtime in Javascript before refresh a grid ?
I would like a button that assign a new value of Tipology, and then refresh a grid with a new values.

Somebody can I help me ?

Thanks,
Rinaldo

Hi Rinaldo,

I suppose that you can do something like that:

source.data = {Tipology: 5};

Hi Peter,
Do you say this to change value and rehtresh data ?

$(“#refresh”).click(function () {
$(‘#jqxgrid’).source.data = {Tipology: 5};
$(‘#jqxgrid’).jqxGrid(‘updatebounddata’);
}

I thinks that $(‘#jqxgrid’).source.data is not correct…
my difficult is that I don’t understand how access and change source.data from $(‘#jqxgrid’) object.

Thanks,
Rinaldo

Hi Rinaldo,

source.data = {Tipology: 5};
Then build a jqxDataAdapter from the source object and set the jqxGrid’s source property to point to the jqxDataAdapter’s instance.
