dataAdapter – AJAX/changing URL and parameters

[HectorPukParticipant]

Hi Folks,

I need a dropdown list to be populated with some kind of filter based on another field.

What I am doing is

var source =
{
datatype: “json”,
datafields: [
{ name: ‘GroupPath’, type: ‘string’},
{ name: ‘NROMovil’, type: ‘string’ },
{ name: ‘PromedioVelocidadMaxExcesiva’, type: ‘string’ }
],
url: ‘services/Consolidado.php?NROMovil=340′, //URL THAT NEEDS LATTER CHANGE
async: false
};

var dataAdapter = new $.jqx.dataAdapter(source);

dataAdapter.dataBind();

Now I need to change the parameter in the URL to services/Consolidado.php?NROMovil=967.

My approach is to change dataAdapter._source.url and do Bind again. Is that the right way to do it?

dataAdapter._source.url=’services/Consolidado.php?NROMovil=967’;
dataAdapter.dataBind();

If not, please let me know what is the sound practice to do it.

Thanks in advance.

Hector.

Hi HectorPuk,

Using internal and not documented properties is wrong. Why you just don’t create a new dataAdapter instance with your updated source object. That’s more correct and clean approach.

Hi Peter,

Thanks and Understood. I will follow your recomendation.

I was looking for examples on dropdown tree, with JSON (source URL, PHP or whatever) and filtering but I was not able to find one; or at least understand one.

So again, I will follow you.

Hector.
