Unable to load data value in simplestore dynamically

[mr.khan]

Hi All,

I am fairly new to ExtJS.
I am trying to load my combo box on depending upon selected value from the previous combo box. (Same Old Country-state scenario) i am making an ajax call and getting values too and assigning in 'data' but it is showing just 2nd character of my variable.

attributeStore = new Ext.data.SimpleStore({
        fields: ['idc','criteria'],
        data  : [ sb ]
});

var tempcriteria = Ext.getCmp('criteriaId');
tempcriteria.bindStore( attributeStore );

from ajax's call I am assigning

sb = ['CITY_NAME','CITY_NAME'],['CNTRY_NAME','CNTRY_NAME'],['STATUS','STATUS']

But all I am getting is ' <single inverted comma>. Since its the 2nd character in sb.
I tried changing data to

data : ['sb']

My combo box is filled with 'b'

Its bit weird thing happening. I even tried

data : [['CITY_NAME','CITY_NAME'],['CNTRY_NAME','CNTRY_NAME'],['STATUS','STATUS']]

which works smoothly.
I am assuming I am making a silly mistake somewhere.
Appreciate any help.

data : [['CITY_NAME','CITY_NAME'],['CNTRY_NAME','CNTRY_NAME'],['STATUS','STATUS']]

An array of arrays is the correct format you should be returning

Hi Aconran,

Thanks for quick response.
Yeah this works

data : [['CITY_NAME','CITY_NAME'],['CNTRY_NAME','CNTRY_NAME'],['STATUS','STATUS']]but when assigning
sb = ['CITY_NAME','CITY_NAME'],['CNTRY_NAME','CNTRY_NAME'],['STATUS','STATUS']
at runtime and then giving

attributeStore = new Ext.data.SimpleStore({
fields: ['idc','criteria'],
data : [ sb ]
});

it is just displaying ' <single inverted comma> in combobox.

Try

sb = [['CITY_NAME','CITY_NAME'],['CNTRY_NAME','CNTRY_NAME'],['STATUS','STATUS']];

attributeStore = new Ext.data.SimpleStore({
        fields: ['idc','criteria'],
        data  : sb
});

Yeah, what you suggested worked.
But when assign the my String to 'sb' it doesnt work.
I understood the problem is I am giving a String to 'data' whereas it is expecting array of array.

Thanks Acronran. I'll now have to convert my String ([['CITY_NAME','CITY_NAME'],['CNTRY_NAME','CNTRY_NAME'],['STATUS','STATUS']])

to array of array, Don't wanna be a burden but any idea how to do that ?

an unsafe way would be to simply eval it.

A safer way would be to stick it into a JSON object, decode it and then use that.

Thanks a lot aconran. Gone with the unsafe way and its working now.
