Ng-click not working on selected list item in autocomplete?
I am unable to select a list item using ng-click. When I clicked on the selected item, I should get the ID of the selected item and the selected item should appear in the search box. But it works fine for key entry, but I also want the selected item to be in the search box on ng-click.
Here is my code.
JS:
angular.module("hmautocomplete", [])
.directive('hmAutocomplete', function ($timeout) {
return {
scope: {
selectedIndex: '=',
hmSuggestions: '=',
hmDropdownid: '@',
hmSelect: '&'
},
link: function (scope, element) {
scope.selectedIndex = 0;
var elem = angular.element(document.getElementById('autotext'));
var list =
angular.element(document.getElementById(scope.hmDropdownid));
list.css('display', 'none');
elem.bind('focus', function () {
scope.selectedIndex = 0;
scope.$apply();
list.css('display', 'block');
});
elem.bind('blur', function () {
$timeout(
function () {
list.css('display', 'none');
}, 100
)
});
elem.bind("keydown", function (event) {
if (list.css('display') === 'none') {
list.css('display', 'block');
}
if (event.keyCode === 40) { //down key, increment
selectedIndex
event.preventDefault();
if (scope.selectedIndex + 1 ===
scope.hmSuggestions.length) {
scope.selectedIndex = 0;
} else {
scope.selectedIndex++;
}
scope.$apply();
} else if (event.keyCode === 38) { //up key, decrement
selectedIndex
event.preventDefault();
if (scope.selectedIndex === 0) {
scope.selectedIndex = scope.hmSuggestions.length - 1;
} else {
scope.selectedIndex--;
}
scope.$apply();
} else if (event.keyCode === 13 || event.keyCode === 9) {
//enter pressed or tab
elem.val(scope.hmSuggestions[scope.selectedIndex].Name);
list.css('display', 'none');
scope.hmSelect(scope.hmSuggestions[scope.selectedIndex]);
scope.$apply();
} else if (event.keyCode === 27) {
list.css('display', 'none');
}
})
}
};
}).directive('hoverClass', function () {
return {
restrict: 'A',
link: function (scope, element, attr) {
element.on('mouseenter', function () {
angular.element(document.getElementsByClassName(attr.hoverClass)).removeClass(attr.hoverClass);
element.addClass(attr.hoverClass);
});
element.on('mouseleave', function () {
element.removeClass(attr.hoverClass);
});
}
};
})
.directive('hmSelectDown', function () {
return {
restrict: 'A',
scope: {
hmSelectDown: '&'
},
link: function (scope, elem, attr) {
var list = angular.element(document.getElementById(scope.hmDropdownid));
elem.bind('click', function () {
scope.hmSelectDown();
list.css('display', 'none');
});
}
};
})
.filter('highlight', function ($sce) {
return function (text, phrase) {
if (phrase)
text = text.replace(new RegExp('(' + phrase + ')', 'gi'), '<span
class="highlighted">$1</span>');
return $sce.trustAsHtml(text);
}
}).controller('demo', function ($scope) {
$scope.fnAutocompleteQuestion = function () {
$scope.items = [{
'Name': 'India'
}, { 'Name': 'United States' },
{ 'Name': 'England' },
{ 'Name': 'Germany' },
{ 'Name': 'London' }, {
'Name': 'Pakistan'
}, {
'Name': 'Nepal'
}, {
'Name': 'Bangladesh'
}];
}
$scope.onselect = function (obj) {
alert(JSON.stringify(obj));
console.log(obj);
}
});
Html:
<div ng-controller="demo">
<hm-autocomplete selected-index="selectedIndex"
hm-textboxid="autotext"
hm-dropdownid="dropdown"
hm-suggestions="items"
hm-select="onselect(items[selectedIndex])">
<input type="text" id="autotext" class="form-control" ng-model="strSearch" ng-change="fnAutocompleteQuestion(strSearch)" />
<ul id="dropdown" class="ngcomplete-dropdown">
<li ng-repeat="item in items | filter: strSearch"
hover-class='ngcompleterowactive'
ng-mouseover='selectedIndex==$index'
ng-class="{'ngcompleterowactive':selectedIndex==$index}"
ng-bind-html="item.Name | highlight:strSearch"
hm-select-down="onselect(item)">
</li>
</ul>
</hm-autocomplete>
</div>

I think you could try this
Js
}).controller('demo', function($scope) {
// code..
$scope.selectedItem;
$scope.selectItem = function(item){
$scope.selectedItem = item;
$scope.strSearch = $scope.selectedItem.Name;
}
// code..
})
Html
<li ng-repeat="item in items | limitTo:10"
class="ngcompleterow"
hover-class='ngcompleterowactive'
ng-click="selectItem(item)"
ng-mouseover='selectedIndex==$index'
ng-class="{'ngcompleterowactive':selectedIndex==$index}"
ng-bind-html="item.Name | highlight:strSearch"
hm-select-down="onselect(item)"
>
</li>
UPDATE
I found why it is not selected by the first click, the reason is because you have this construct:
elem.bind('focus', function () {
scope.selectedIndex = 0;
scope.$apply();
list.css('display', 'block');
});
elem.bind('blur', function () {
$timeout(
function () {
list.css('display', 'none');
}, 100
)
});
So, if you remove it and refactor this:
JS:
.controller('demo', function($scope) {
// code
$scope.blurDropdown = function(){
// same thing as $timeout
setTimeout(function(){
$scope.showDropdown = false;
$scope.$apply();
}, 100)
// code
});
}
And HTML
<input ng-focus="showDropdown = true" ng-blur="blurDropdown()" type="text" id="autotext" class="form-control" ng-model="strSearch" />
<ul id="dropdown" data-ng-show="showDropdown" class="ngcomplete-dropdown">
After this fix, I can click on any item that matches the search pattern.
