passing multiple arguments or object in (click)

问题

Problem is to pass the object or multiple arguments from template to component and use them to add data to API.

task.service.ts

addTasks(task: Task): Observable<Task>{
 let headers = new Headers({'Content-type': 'application/json'});
 let options = new RequestOptions({ headers: headers });
 return this.http.post(this.tasksUrl, {task}, options)
 .map(this.extractData)
 .catch(this.handleError);

}

task.component.ts

addTasks(task){
this.taskService.addTasks(task)
.subscribe(
  task => this.tasks.push(task),
  error => this.errorMessage = <any> error
);

}

Template Inputs:

<input #todoTime type="text" class="form-control">&nbsp;
<input #todoName type="text" class="form-control">

Template Button:

<button name="todoAdd" (click)="addTasks({name: todoName.value, time: todoTime.value}); todoName.value='',todoTime.value='' ">add</button>

回答1:

Replace the comman(,) with a semicolon when you are handling the click event for the button. That should work.

<button name="todoAdd" (click)="addTasks({name: todoName.value, time: todoTime.value}); todoName.value=''; todoTime.value='' ">add</button>

I have created this simple Plnkr that shows object is getting passed to addTasks() function.
