從 dart 呼叫 javascript
參考官網文章: http://dartdoc.takyam.com/articles/js-dart-interop/
// index.html
<html><head><meta charset='utf-8'></head><body>
<script type='application/javascript' src='hello.js'></script>
<script type='application/javascript' src='main.js'></script>
</body></html>
// hello.js
var greeting="Hello"; // 1. variable
function fun( ){ //2. function
console.log("How are you?");
}
class Rectangle {
constructor(width, height) {
this.width = width;
this.height = height;
}
}
function rectangle(width, height) { // 3. object
return new Rectangle(width, height); // return an object
}
// main.dart
import 'dart:js';
void main() {
var greeting = context['greeting']; // 1.
print("$greeting");
context.callMethod('fun'); //2.
final rectangle = JsObject(context['rectangle'], [5, 1]); //3.
print(rectangle['width']);
}
