我有一个 Angular 4 表单,我正在尝试提交数据
HTML 代码
<form class="form-horizontal" [formGroup]="signupForm"
(ngSubmit)="onFormSubmit()" >
<fieldset>
<legend>Scheduler</legend>
<!--- Gender Block -->
<div class="form-group">
<label for="scheduleJob">Schedule Job</label>
<input type="text" formControlName = "schedulejob"
id="scheduleJob"
placeholder="Schedule Job">
按钮代码
<div class="form-group">
<button type="reset" class="btn btn-default">Cancel</button>
<button type="submit" class="btn btn-primary">Submit</button>
</div>
Scheduler.TS 文件
import { Component, OnInit } from '@angular/core';
import { Scheduler } from 'rxjs/Scheduler';
/* Import FormControl first */
import { FormBuilder, FormGroup, Validators } from '@angular/forms';
@Component({
selector: 'app-scheduler',
templateUrl: './scheduler.component.html',
styleUrls: ['./scheduler.component.css']
})
export class SchedulerComponent implements OnInit {
//Gender list for the select control element
private scheduleTypeList: string[];
//Property for the user
private scheduler:Scheduler;
private signupForm: FormGroup;
constructor(private fb:FormBuilder) { }
ngOnInit() {
this.scheduleTypeList = ['Type 1', 'Type 2', 'Type 3'];
this.signupForm = this.fb.group({
schedulejob: ['', Validators.required] ,
frequency: ['', Validators.required],
days: ['', Validators.required],
zone: ['', Validators.required],
schedulerjobtype:['', Validators.required]
})
}
public onFormSubmit() {
this.scheduler = this.signupForm.value;
if(this.signupForm.valid) {
this.scheduler = this.signupForm.value;
console.log(this.scheduler);
// alert(this.scheduler);
/* Any API call logic via services goes here */
}
//alert(this.scheduler);
console.log(this.scheduler);
}
}
为什么在提交点击和警报时执行没有传递到 onFormSubmit 或 console.log 不打印值?
就像我在评论中所说,如果您的按钮不在表单内,它将不会提交。
所以改为:
<form>
...
<button type="submit">Submit</button>
</form>
但是,如果您做得有点不同,则可以将其放在外面,如本问题中所述。
<form>
标签来包装我的表单。
<form [formGroup]="form" (ngSubmit)="submit()">
...
<button type="submit" hidden #btn></button>
</form>
...
<button (click)="btn.click()">Submit</button>
<form class="form-horizontal"
[formGroup]="signupForm"
(ngSubmit)="onFormSubmit()" >
<fieldset>
<legend>Scheduler</legend>
<!--- Gender Block -->
<div class="form-group">
<label for="scheduleJob">Schedule Job</label>
<input type="text" formControlName = "schedulejob"
id="scheduleJob"
placeholder="Schedule Job">
<!-- Button Code Here -->
<div class="form-group">
<button type="reset" class="btn btn-default">Cancel</button>
<button type="submit" class="btn btn-primary">Submit</button>
</div>
<!-- Form ends here -->
</form>
<form id="formID">
...
<button type="submit" form="formID">Submit</button>
</form>
event.stopProgogation()
和
event.preventDefault()
。当用户单击按钮时,这些方法调用会阻止表单提交。我的问题的解决方案只是删除这些方法调用。
