Jquery ui 角度2+;jquery自动完成组件:无法调用spec文件内组件的方法
我在angular2中使用了jquery自动完成方法,它调用服务从api获取数据。 这里是myComponent.tsJquery ui 角度2+;jquery自动完成组件:无法调用spec文件内组件的方法,jquery-ui,angular,jquery-autocomplete,angular2-testing,Jquery Ui,Angular,Jquery Autocomplete,Angular2 Testing,我在angular2中使用了jquery自动完成方法,它调用服务从api获取数据。 这里是myComponent.ts export class myComponent { private myVar; private binding1; private binding2; constructor( @Inject(ElementRef) private elementRef: ElementRef,private _myService: MyService) { } public metho

即使调用method1和method2,我也无法在规范中模拟this.myVar?我应该如何测试各种方法?实际上并不是一个答案(并不真正理解问题),而是一些建议(参见代码中的注释):
导出类myComponent{
私有myVar;
私人绑定1;
私人绑定2;
//删除“@Inject(ElementRef)”,因为当类型为
//也有'ElementRef'`
构造函数(private-elementRef:elementRef,private\u-myService:myService){
}
public method1(){返回this.myVar.val().toUpperCase();}
public method2(){返回this.myVar.val(“”;}
私人恩戈尼尼特(){
//var_this=这个;
this.myVar=$(this.elementRef.nativeElement).children().eq(0).autocomplete({
来源:(请求,回调)=>{//{//你说的mockthis.myVar
是什么意思?this.myVar
存储jQuery对象,调用spec文件中的method1
,它说找不到.val()
的未定义。所以这个.myVar
没有被什么模仿?你为什么期望它被模仿?我只想在spec文件中调用method1
。我所说的模仿是指它包含在ngOnInit
中返回的jQuery对象。我更新了我的spec文件。你现在明白这个问题了吗?我没有看到你做任何会有问题的事情d导致myVar
或method1
被嘲笑。我不明白:-/
fit(‘my component test file’,inject([TestComponentBuilder, MyComponent, ElementRef], (tcb:TestComponentBuilder) => {
tcb.createAsync(MyComponent)

const element = fixture.debugElement.nativeElement;
