提交后如何重置角度形式并设置默认值 [英] how to reset angular form and set default values after submitting

问题描述

我的预期结果是在提交表单后重置表单，并将其默认值绑定到formGroup控件.我试图通过在表单提交上调用reset()来将表单重新设置为其默认数据.请告诉我如何在日期和时间字段中重置默认值.

My expected results is to reset the form after it has been submit and set its default values binded to the formGroup control. I am attempt to reset the form to its default data after submitting by calling reset() on the form submit. Please advise me on how can I reset the default value in the date and time field .

示例:

pickupDate = new Date().toISOString().slice(0,10);
pickupTime = moment().format() ;

onSubmit(orderData: Order){
        this.apiService(orderData).subscribe( order => {
                 orderForm.reset()
})
}

请帮助谢谢

推荐答案

提交表单后.您正在呼叫

After submitting your form. you are calling

this.yourForm.reset()

然后，您可以将初始值修补到这种形式.

Then you can patch initial values to the form like this.

this.yourForm.patchValue({
  firstControllerName: this.initialValues.value1,
  secondControllerName: this.initialValues.value2,
  // other controller names goes here
});

希望这会有所帮助.
