I want you to show a little tutorial how to create a searchfield to filter a list, grid or something else which has a relation to a store. I want to show this to you by using a list.
If you need you can download the Architect 3 project from here: https://mega.co.nz/#!9NFyRCLL!98dkUmISgGO_p0crDI8YExINmf5ORCglkDrWjuRyu7Y
First we create a Store with a model and some data in it. If you want to take a look, you'll have a link here: https://gist.github.com/difa1/9115899
Second we need to create a simple list in a panel:
Third we would like to implement the searchfield. You can place it however you want.
Now that the basics a build we build a new controller where all the logic is stored. So lets go to Step 4 and create the controller with 2 listeners: keyup and clearicontap:
The logic for the clearicontap is pretty simple... All we want is to clear all filters. All we need is the clearfilter method :
The keyup is a bit more tricky, why I like to use a basic function for it. I tried to explain all steps in the coding itself. If anything were unclear, you could contact me on Google+ ;)

First we create a Store with a model and some data in it. If you want to take a look, you'll have a link here: https://gist.github.com/difa1/9115899
Second we need to create a simple list in a panel:
Ext.define('MyApp.view.MyPanel', {
extend: 'Ext.Panel',
requires: [
'Ext.dataview.List',
'Ext.XTemplate'
],
config: {
layout: 'vbox',
items: [
{
xtype: 'list',
flex: 1,
itemTpl: ['{name}, {namelast}'],
store: 'persons'
}
]
}
});
Third we would like to implement the searchfield. You can place it however you want.
Ext.define('MyApp.view.MyPanel', {
extend: 'Ext.Panel',
requires: [
'Ext.field.Search',
'Ext.dataview.List',
'Ext.XTemplate'
],
config: {
layout: 'vbox',
items: [
{
xtype: 'searchfield',
docked: 'top',
itemId: 'storeSearchField',
label: 'Field'
},
{
xtype: 'list',
flex: 1,
itemId: 'mylist',
itemTpl: ['{name}, {namelast}'],
store: 'persons'
}
]
}
});
Now that the basics a build we build a new controller where all the logic is stored. So lets go to Step 4 and create the controller with 2 listeners: keyup and clearicontap:
Ext.define('MyApp.controller.logicController', {
extend: 'Ext.app.Controller',
config: {
control: {
"searchfield#storeSearchField": {
clearicontap: 'onStoreSearchFieldClearicontap',
keyup: 'onStoreSearchFieldKeyup'
}
}
},
onStoreSearchFieldClearicontap: function(textfield, e, eOpts) {
// Logic
},
onStoreSearchFieldKeyup: function(textfield, e, eOpts) {
// Logic
}
});
The logic for the clearicontap is pretty simple... All we want is to clear all filters. All we need is the clearfilter method :
onStoreSearchFieldClearicontap: function(textfield, e, eOpts) {
Ext.getStore('persons').clearFilter();
}
The keyup is a bit more tricky, why I like to use a basic function for it. I tried to explain all steps in the coding itself. If anything were unclear, you could contact me on Google+ ;)
onStoreSearchFieldKeyup: function(textfield, e, eOpts) {
this.filterList(textfield, Ext.getStore('persons'));
},
filterList: function(textfield, store) {
// Get the searchfield content
var value = textfield.getValue();
// Clear previous filters
store.clearFilter();
// Check for search value, if not present we don't need to to anything...
if (value) {
// Split search value: Space --> 2 custom values!
var searches = value.split(' '),
regexps = [],
i;
// Loop search values and build regex
for (i = 0; i < searches.length; i++) {
// Ignore spaces
if (!searches[i]) continue;
// Regex array
regexps.push(new RegExp(searches[i], 'i'));
}
// Filter the store
store.filter(function(record) {
// Clear matches first
var matched = [];
// Loop all regex expressions
for (i = 0; i < regexps.length; i++) {
var search = regexps[i];
var didMatch;
didMatch = record.get('name').match(search) ||
record.get('namelast').match(search);
// You can add as many model fields as you want! --> record.get('city1').match(search) ||
// Write match to array
matched.push(didMatch);
}
// Nothing found? Do not return anything ;)
if (regexps.length > 1 && matched.indexOf(false) != -1) {
return false;
} else {
// Found something? Just return to store ;)
return matched[0];
}
});
// Finally load store
store.load();
}
