Question

我正在使用primeNg的动态对话框，我必须将2个变量从组件A传递到组件B中，而组件B是我从A动态打开的

showSkillDetailModal(categoryId: number, skillId: number) {
    const ref = this.dialogService.open(SkillDetailsComponent, {
      width: '70%',
      data: {
        categoryId: categoryId,
        skillId: skillId 
      }
    });
  }

这是用于打开动态对话框SkillDetailsComponent的代码，我发送的数据位于数据数组-> categoryId＆skillId

constructor(
    public ref: DynamicDialogRef,
    public config: DynamicDialogConfig,
    private selfService: SelfDataService
  ) {}

  ngOnInit() {
    this.selfService.getMySkillList(categoryId, skillId).subscribe(response => {
    }, error => {
      console.log(error);
    })
  }

但是我无法在SkillDetailsComponent中获得这两个变量... 有什么想法可以前进吗？

d = {'redFish': {'redFish': 'inf', 'blueFish': 9, 'twoFish': 10, 'oneFish': 6}, 'blueFish': {'redFish': 9, 'blueFish': 'inf', 'twoFish': 11, 'oneFish': 10}, 'twoFish': {'redFish': 10, 'blueFish': 11, 'twoFish': 'inf', 'oneFish': 8}, 'oneFish': {'redFish': 6, 'blueFish': 10, 'twoFish': 8, 'oneFish': 'inf'}}

lowestPair = ['name1', 'name2', float('inf')]
for name1 in d.keys():
    for name2 in d[name1].keys():
        if float( d[name1][name2] ) < lowestPair[2]:
            lowestPair = [name1, name2, d[name1][name2]]

averageList = []
for name in lowestPair[0:2]:
    for otherName in d[name].keys():
        if otherName not in lowestPair:
            average = (float( d[lowestPair[0]][otherName] ) + float( d[lowestPair[1]][otherName] ))/2
            d[name][otherName] = average 
            averageList.append(average) 

print( averageList )
