错误消息che不是函数”表明变量che用作函数存在问题。根据您提供的代码，似乎che既用作数组又用作函数参数，这可能导致错误。

id: any;

loginsubmit(id: any) {
 console.log("button works");
 const che = [];

 this.admincreation.getdatas(id).subscribe((data: any) => {
 // Remove the redundant curly braces here
 const adminl = data.find((b: any) => {
  return b.loginemail === this.Login.value.loginemail && b.loginpassword 
 === this.Login.value.loginpassword;
  });

  if (adminl) {
  Swal.fire('success', 'Admin is logged in successfully', 'success'); // Fixed the Swal.fire line
  this.Login.reset();
  this.route.navigate(['/superadmin']);
} else {
  // user login logic
  this.userLogin(id);
}
});
}

userLogin(id: any) {
this.sign.getlogin(id).subscribe((res: any) => {
const user = res.find((b: any) => {
  return b.loginemail === this.Login.value.loginemail && b.loginpassword === this.Login.value.loginpassword;
});

if (user) {
  Swal.fire({
    icon: 'success',
    title: 'Successfully Logged In',
    text: 'Login Successfully',
  });
  this.route.navigate(['/generalusers']);
  this.dialog.open(UseraccesdelogComponent, {
    width: '800px',
    height: '600px',
  });
  this.Login.reset();
  }
  });
 }

 getlogin(id: any) {
  return this.http.get(this.urls, id);
 }

 getdatas(id: any) {
 return this.http.get(this.urls, id);
}

字符串
我已经删除了多余的花括号，修复了Swal.fire行，并调整了代码中的一些注解。确保代码的结构如上所示，并且在正确登录后应该导航到下一页。
@Priyasingh如果你有，请问。
