未显示Angular 4按钮禁用图标

Question

Console image of the inspected element

问题：当我的按钮具有已禁用的属性并且我将鼠标悬停在该按钮上时，未显示已禁用的图标。

有人可以建议我如何解决这个问题吗？

我已在下面附上了一个代码段：

<form (ngSubmit)='onSubmit(form)' *ngIf="!submitted" #form="ngForm"> 
    <input required #password="ngModel" [(ngModel)]="stackDefaultData.password" name="password" type="password" class="form-control"> 
    <button type="submit" [disabled]="form.invalid">Submit</button> 
</form>     

Answer 1

这应该有效：

def send_simple_message(mailtext, filename=""):
  requests.post("https://api.mailgun.net/v3/mydomain.in/messages",
  auth=("api", "key-1234"),
  files=[("attachment", open(filename))],
  data={"from": "Credit Card Manager <creditcards@mydomain.in>",
  "to": ["bob@mydomain.in"],
  "subject": "Summary of Credit Card payments due",
  "text": mailtext})
