Question

我有一个带有垫芯片列表的垫形式。表格位于草稿对话框中。当我关闭对话框时，仅发送芯片列表中的最后一个元素，但我需要所有元素。

这是我的代码：

import matplotlib.pyplot as plt
import matplotlib.ticker as ticker
import numpy as np

@ticker.FuncFormatter
def major_formatter(x, pos):
    label = str(-x) if x < 0 else str(x)
    return label

y = np.linspace(-3000,-1000,2001)
fig, ax = plt.subplots()
ax.plot(y)
ax.yaxis.set_major_formatter(major_formatter)
plt.show()

我的对话框形式：

let dialogRef = this.dialog.open(DialogForm, {
    width: '60vw',
    data: { id : data.id }
});
dialogRef.afterClosed().subscribe(cars => {
    if (cars!= null) {
        console.log(cars ); // I only get the last car
    }
});

我的模板

 constructor(public dialogRef: MatDialogRef<DialogForm>, @Inject(MAT_DIALOG_DATA) public data: any, public formBuilder: FormBuilder) { }

// Initialize with the cars from DB
this.carService.getCars(12)
  .subscribe(cars=> {
    this.cars= <Car[]>cars;
});

 this.carForm = new FormGroup({
  id: new FormControl(this.data.id),
  cars: new FormControl(this.cars, {
    validators: Validators.required
  })
}, { updateOn: 'change' });

Mat对话框仅发送mat-chip-list中的最后一个元素
