我正在尝试使用带有Angularjs(1.5)的jQuery(2.2.1)Select2(3.5.2),但是很难从选择框中获取数据。我已经尝试了ui-select并且我可以检索数据......但是在搜索时经常会崩溃浏览器,速度非常慢且整体不稳定(5000-10000项)。即使有大量的条目,jQuery Select2也是快速且响应迅速的,但是当我选择一个选项时,我似乎无法获得该对象。
<head>
<script src="~/Scripts/angular.min.js"></script>
<script src="~/Scripts/CustomScripts/app.js"></script>
<script src="~/Scripts/jquery-2.2.1.js"></script>
<script src="~/Scripts/select2.js"></script>
<script type="text/javascript">
$(document).ready(function () {
$(".sel").select2();
});
</script>
<head>
<body ng-app="app" ng-controller="MainCtrl">
<select class="sel" data-ng-model="country.selected" ng-options="country.Name for country in countries | orderBy: 'Name'">
<body>
app.js
var app = angular.module('app', []);
app.controller('MainCtrl', ['$scope', '$http', function ($scope, $http) {
$scope.country = {};
$scope.countries = [{
name: 'Australia',
}, {
name: 'United States'
}, {
name: 'United Kingdom'
}];
}]);
有没有办法让这两个很好地工作?

Select2的Angular版本可用。点击此处:https://www.npmjs.com/package/angular-select2
(守则在这里:https://github.com/rubenv/angular-select2)
此Angular Library使用Select2作为依赖项,并帮助在表单中集成Select2。

通过凉亭安装&#34; angular-ui-select&#34;:&#34; = 0.12.1&#34; 然后在你的HTML ......
<ui-select multiple
class="col-md-8 input-sm"
on-select="someMethod()"
on-remove="someMethod()"
ng-model="country.selected"
theme="bootstrap">
<ui-select-match placeholder="Select field...">{{$item.name}}</ui-select-match>
<ui-select-choices
repeat="field in countries | filter:$select.search">
<div ng-bind-html="field.name | highlight: $select.search"></div>
</ui-select-choices>
</ui-select>
永远不要直接初始化jQuery插件。通过互联网搜索如何将jQuery模块与Angular集成(它可能看起来有点复杂,但它非常简单。以你所做的方式调用它将永远无法工作....
<script type="text/javascript">
$(document).ready(function () {
$(".sel").select2();
});
</script>
ui-select的替代方案是:
angular-chosen ("angular-chosen-localytics": "~1.0.7",)

在搜索了如何从jQuery访问$ scope函数之后,我发现使用angular.element.scope()。function(x)将允许我在“change”事件中传递每个select2元素的键,成角度,然后可以操纵。
<script type="text/javascript">
$(document).ready(function () {
$(".sel").select2({
placeholder: "Select a project..."
})
.on("change", function (e) { angular.element(document.getElementById("MainCtrl")).scope().testfunction(); });
});
</script>

您可以使用此插件,
ngx-select2
添加jQuery和Select2库
<link href="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/css/select2.min.css" rel="stylesheet" />
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.2.1/jquery.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/select2/4.0.3/js/select2.min.js"></script>
如果要添加javascript和CSS库,则必须从angular.json
示例中添加:
"styles": [
"node_modules/bootstrap/dist/css/bootstrap.css",
"src/styles.css",
"src/assets/css/select2.min.css"
],
"scripts": [
"node_modules/bootstrap/dist/js/bootstrap.js",
"node_modules/jquery/dist/jquery.js",
"src/assets/js/select2.min.js"
]
安装ngx-select2
npm i ngx-select2
使用select2组件
import { LSelect2Module } from 'ngx-select2';
@NgModule({
declarations: [
AppComponent
],
imports: [
BrowserModule,
FormsModule,
LSelect2Module
],
providers: [],
bootstrap: [AppComponent]
})
export class AppModule { }
以html
<l-select2 [(ngModel)]="selected" [data]="data" [options]="options" [disabled]="false" (valueChange)="valueChange($event)"></l-select2>
选项
select2
组件ngModelChange
