Maybe somebody can help me with a little problem. I am pretty new in the field of web programming, but I have programming experience. I would like to develop a small website that uses angularjs and ui-grid. Unfortunately the filtering is not working from external input fields.
Could somebody please tell me where my programming bug is?
The code can be found here: http://plnkr.co/edit/fiA666OzpBqpTrCiuXER?p=preview
var myDummyData = [{name: "Moroni", age: 50},
{name: "Tiancum", age: 43},
{name: "Jacob", age: 27},
{name: "Nephi", age: 29},
{name: "Enos", age: 34}];
var myDummyData2 = [{name: "aTest", age: 50},
{name: "bTest1", age: 43},
{name: "cTest2", age: 27},
{name: "dTest3", age: 29},
{name: "eTest4", age: 34}];
$scope.filterOptions = {
filterText: ''
};
$scope.gridOpts = {
data: myDummyData,
enableFiltering: true,
columnDefs: [
{name: 'Name', field: 'name', enableFiltering: true
, filter: {
term: $scope.filterOptions.filterText //DOES NOT WORK... BUT WHY
}
},
{name: 'Price', field: 'age'}
]
};
$scope.updateData = function(newValue){
//console.log($scope.gridOpts.data);
console.log($scope.gridOpts.columnDefs[0].filter);
$scope.gridOpts.columnDefs[0].filter = {term: newValue};
console.log("Scope nameid set " + $scope.gridOpts.columnDefs[0].filter.term); //is set but no update
//$scope.$apply(); //not possible gives error! WHY??
//$scope.gridOpts.data = myDummyData; //for testing works
};
$scope.swapData = function () {
if ($scope.gridOpts.data === myDummyData) {
$scope.gridOpts.data = myDummyData2;
}
else {
$scope.gridOpts.data = myDummyData;
}
};
//DOES NOT WORK BUT WHY
// $scope.$watch('filterOptions.filterText', function (newValue, oldValue) {
// if ($scope.filterOptions.filterText) {
// $scope.filteringText = newValue;
// $scope.updateData(newValue);
// }
// });
The idea is to have a navigation bar that contains a search field. Later I want to filter depending on rangesliders on further columns. However not even the standard string filtering works in my example.
Questions:
I looked around for answers, but either this is directly a problem of the binding that I cannot grasp, a mere programming js problem, or a ngGrid update to ui-grid problem.
Thanks a lot in advance
The answer to your first question, they have not really made a global search option for the UI-Grid yet, so you have to do a bit of a work around. The current way that the column filters work is angular watches the column filter input field for a change, and when you type in the box, it refreshes its filter. So your filter will not apply unless you force this input box to fire the change event. The workaround is to simply filter the data and reload. For example:
In your HTML input search box, add a refresh
<input ng-model="searchText" ng-change="refreshData()" placeholder="Search...">
then in your app.js
$scope.refreshData = function() {
$scope.myGrid.data = $filter('filter')($scope.data, $scope.searchText);
};
oh, and don't forget to include $filter in your controller
app.controller('myController', function($scope, $filter) {}
I forked your example and modified it with this workaround. Check it out here: http://plnkr.co/edit/Tr9cNm0lDy62dmF7LNlr?p=preview
