在Dart中使用Jquery UI [英] use Jquery UI in Dart

问题描述

我想在Dart中创建一个简单的对话框，我认为使用现有的javascript库更容易。
这里可以找到基本示例，基本上是

I'm trying to create a simple dialog in Dart and I thought it was easier to use existing javascript libraries. Here you can find the basic example, basically

$( "#dialog" ).dialog();

在internet和stackoverflow，你可以找到1000个例子，
我想这是正确的方式：

On internet and stackoverflow you can find 1000 examples but none works to me. I suppose this is the correct way:

import 'dart:js' as js;
//[...]
var jquery = new js.JsObject(js.context['jQuery']);
var myob = jquery('#dialog').dialog();

我得到的只是这个错误：

All I get is this error:

打破异常：类'JsObject'没有实例方法调用。

Breaking on exception: Class 'JsObject' has no instance method 'call'.

Dart的文档？

推荐答案

基本上，有两个库可以与js交互：dart:js 和软件包：js a>。已在 package：js 之后创建了 dart：js ，并且大多数stackoverflow答案使用了 package：js 值得downvote这些答案...）

Basically, there are 2 libraries to interop with js : dart:js and package:js. dart:js has been created after package:js and most of the stackoverflow answers use package:js and are still valid (it isn't worth to downvote these answers...)

package：js 提供了一个更简单的Api， （因为 package：js 使用dart：mirrors 和 noSuchMethod ）。

package:js provides a simpler Api that comes at the cost of an increase of the js size (because package:js uses dart:mirrors and noSuchMethod).

package：js ：

import 'package:js/js.dart' as js;

main() {
  js.context.$("#dialog").dialog();
}

---

：js ：

import 'dart:js' as js;

main() {
  js.context.callMethod(r'$', ['#dialog']).callMethod('dialog');
}
