ReferenceError：未定义 MouseEvent

Question

我正在尝试在使用 angular/universal-starter (TypeScript 2.x) 作为主干的项目中使用 ng2-select。

（我尝试在 angular-cli 生成的项目中添加 ng2-select，但效果很好）

在添加这两行之后：

import { SELECT_DIRECTIVES } from 'ng2-select/ng2-select';

@Component({
  directives: [SELECT_DIRECTIVES],
  ...

我的终端中已经出现错误：

这是我的 tsconfig.json 文件：

{
  "compilerOptions": {
    "emitDecoratorMetadata": true,
    "experimentalDecorators": true,
    "target": "es5",
    "module": "commonjs",
    "removeComments": true,
    "sourceMap": true,
    "lib": ["es6", "dom"]
  },
  "include": [
    "node_modules/@types/**/*.d.ts",
    "src/**/*.ts"
  ],
  "exclude": [
    "node_modules",
    "!node_modules/@types/**/*.d.ts"
  ],
  "compileOnSave": false,
  "buildOnSave": false,
  "atom": {
    "rewriteTsconfig": false
  }
}

Answer 1

我想这个错误是因为指令没有正确加载造成的。

1) 确保正在导入正确的组件，并验证是否定义了 MouseEvent

2) 验证是否所有组件都在导出；

3) 在

@Component({
  directives: [SELECT_DIRECTIVES],
  ...

确保SELECT_DIRECTIVES 不是数组对象。如果是，我认为您应该尝试使用

[ ...SELECT_DIRECTIVES ]

Answer 2

是因为https://github.com/valor-software/ng2-select/issues/258。
