I have data structure like this:
$scope.data = [
{
title: "Title1",
countries: ['USA', 'Canada', 'Russia']
},
{
title: "Title2",
countries: ['France', 'Germany']
}
];
Ie each item has array of country names.
I'm showing this data like this:
<tr ng-repeat="dataItem in data">
I want allow user to filter this list by providing list of countries in input:
How to acheive this?
Currently I'm did something like this:
<input ng-model="searchFilter.countries">
...
<tr ng-repeat="dataItem in data | filter: searchFilter: true">
But obviously it works only for 1 country, not for array of countries listed in input using comma.
A simple solution, without a custom filter:
HTML:
<input ng-model="countries" ng-list>
<tr ng-repeat="dataItem in data | filter:countryFilter">
JS:
$scope.countryFilter = function(dataItem) {
if (!$scope.countries || $scope.countries.length < 1)
return true;
var matched = false;
$scope.countries.filter(function(n) {
matched = matched || dataItem.countries.indexOf(n) != -1
});
return matched;
};
I have created an example here .
It takes use of ngList
as Zahori recommended and defines a custom filter for countries.
myApp.filter('MyFilter', function() {
return function(items, countries) {
if (!angular.isUndefined(items) && !angular.isUndefined(countries) && countries.length > 0) {
var filtered = [];
angular.forEach(items, function(item) {
angular.forEach(countries, function(currentCountry) {
if(item.countries.indexOf(currentCountry) >= 0 ) filtered.push(item);
});
});
return filtered;
} else {
return items;
}
};
});
Your Input is just a String and not an Array. You can use ngList for this purpose.
Here is a good example how to use it: https://docs.angularjs.org/api/ng/directive/ngList
searchFilter should be a method on your $scope. Otherwise by default it searches on string only.
$scope.searchFilter = function (dataItem) {
//your search logic here and return true/false.
};
