我正在困扰着另一个错误,因为我注意到我正在使用onSubmitClicked()
函数的两个按钮上的调用形式:
最初看起来像这样:
<button mat-raised-button (click)="onBackClicked()">
Back
</button>
<button mat-raised-button type="submit">
Submit
</button>
无论我单击哪个按钮,都将呼叫onSubmitClicked()
。只需先通过“后退”按钮调用onBackClicked()
。从“提交”按钮中删除type="submit"
不会改变任何内容。
<form [formGroup]="placeInfoForm" (ngSubmit)="onSubmitClicked()">
<div>
<mat-form-field style="width: 100%;">
<input matInput placeholder="Name" formControlName="name"/>
</mat-form-field>
</div>
<div fxLayout="row" fxLayoutAlign="center">
<button mat-raised-button (click)="onBackClicked()">
Back
</button>
<button mat-raised-button>
Submit
</button>
</div>
</form>
提交功能:
onBackClicked() {
console.log('onBackClicked()')
}
onSubmitClicked() {
console.log('onSubmitClicked()');
}
答案 0 :(得分:0)
除非明确指定,否则<button>
中的任何<form>
都将尝试提交表单。
尝试一下:
<button mat-raised-button type="button" (click)="onBackClicked()">
Back
</button>
