我在我的页面上使用AjgularJS，并希望添加一个字段以使用来自jqueryui的自动完成功能，并且自动完成功能不会触发ajax调用。
我已经在没有angular的页面上测试了脚本（ng-app和ng-controller），并且效果很好，但是当我将脚本放在带有angularjs的页面上时，它将停止工作。
任何想法？
jquery脚本：
$(function () {
$('#txtProduct').autocomplete({
source: function (request, response) {
alert(request.term);
},
minLength: 3,
select: function (event, ui) {
}
});
});
结论：jQueryUI的自动完成小部件必须从AngularJS的自定义指令内部进行初始化，例如：
标记
<div ng-app="TestApp">
<h2>index</h2>
<div ng-controller="TestCtrl">
<input type="text" auto-complete>ddd</input>
</div>
</div>
Angular脚本
<script type="text/javascript">
var app = angular.module('TestApp', []);
function TestCtrl($scope) { }
app.directive('autoComplete', function () {
return function postLink(scope, iElement, iAttrs) {
$(function () {
$(iElement).autocomplete({
source: function (req, resp) {
alert(req.term);
}
});
});
}
});
</script>
app.factory('autoCompleteDataService', [function() {
return {
getSource: function() {
//this is where you'd set up your source... could be an external source, I suppose. 'something.php'
return ['apples', 'oranges', 'bananas'];
}
}
}]);
用于设置自动完成插件的指令。
app.directive('autoComplete', function(autoCompleteDataService) {
return {
restrict: 'A',
link: function(scope, elem, attr, ctrl) {
// elem is a jquery lite object if jquery is not present,
// but with jquery and jquery ui, it will be a full jquery object.
elem.autocomplete({
source: autoCompleteDataService.getSource(), //from your service
minLength: 2
});
}
};
});
并在标记中使用它...请注意ng模型使用您选择的内容在$ scope上设置一个值。
<div ng-controller="Ctrl1"> <input type="text" ng-model="foo" auto-complete/> Foo = {{foo}} </div>
这只是基础，但希望能有所帮助。
app.factory("AutoCompleteService", ["$http", function ($http) {
return {
search: function (term) {
return $http.get("http://YourServiceUrl.com/" + term).then(function (response) {
return response.data;
});
}
};
}]);
指令：
app.directive("autocomplete", ["AutoCompleteService", function (AutoCompleteService) {
return {
restrict: "A",
link: function (scope, elem, attr, ctrl) {
elem.autocomplete({
source: function (searchTerm, response) {
AutoCompleteService.search(searchTerm.term).then(function (autocompleteResults) {
response($.map(autocompleteResults, function (autocompleteResult) {
return {
label: autocompleteResult.YourDisplayProperty,
value: autocompleteResult
}
}))
});
},
minLength: 3,
select: function (event, selectedItem) {
// Do something with the selected item, e.g.
scope.yourObject= selectedItem.item.value;
scope.$apply();
event.preventDefault();
}
});
}
};
}]);
html：
<input ng-model="YourObject" autocomplete />
var myApp = angular.module("employeeSearchModule",[]);
myApp.controller("employeeSearchController",function($scope,$http){
$scope.message= "Welcome to angular js..."
});
myApp.directive('employeesearchautocomplete', function() {
return {
restrict: 'A',
require : 'ngModel',
link : function (scope, element, attrs, ngModelCtrl) {
element.autocomplete({
source : function(request, response) {
$.ajax({
type : "POST",
url : "searchEmployee.html",
data : request,
success : response,
dataType : 'json'
});
},
select : function(event, ui) {
event.preventDefault();
if (ui.item.value == '-1') {
scope.employeeName ='';
scope.$apply();
} else {
scope.employeeName = ui.item.label;
scope.$apply();
}
},
focus : function(event, ui) {
event.preventDefault();
scope.employeeName = ui.item.label;
scope.$apply();
},
change : function(event, ui) {
if (!ui.item) {
scope.employeeName ='';
scope.$apply();
}
}
},{
minLength : 2
});
}
}
});
