Select from array, is it possible?

[yuryn1961]

Hi,

I've got a javascript array:

var x = [
{id:22, name:'Merry'},
{id:26, name:'Poppins'},
{id:345, name:'Popcorn'}
];

Is it possible to create with Sencha Core a method which returns a sub array by a given param, like SQL command (select elements where name like '%Pop%').

function x(x, 'Pop') { } will returns:
[
{id:26, name:'Poppins'},
{id:345, name:'Popcorn'}
}.
Any help will be appreciate.
Thanks

You can use RegEx but you need something to look at the object. We have one for an array of strings.

What you're looking for, I think, is the function Ext.Array.filter which can be used like so:

var pops = Ext.Array.filter(array, function(item) {
    return item.name.indexOf('Pop') != -1;
});

You can also take a look at the MixedCollection class, which is a beefed up Array.

See how you can filter data in stores:

Thanks burnnat, I tried it, it does not work with Ext Core (as the LesJ's solution), but your reply helped me.
Here is my code:
function selectFromArray(arr, s){
var result=new Array();
Ext.each(arr, function(item){
if(item.name.indexOf(s) > -1){
result.push(item);
}
});
return result;
}

Thanks to all again
