Topic: Different mdb-select labels depending on whether a value has been selected or not

1001albertpadilla free asked 5 years ago


How can I have different mdb-select labels depending on whether a value has been selected or not? For example, I want the label "* Department" if there's no selected value. But only "Department" if a value has been selected. mdb-select is set to start with a blank option.

How do you set the default value? Do you use reactive or template-driven forms?

        <mdb-select [(ngModel)]="employee.department.id" [options]="departments" name="departmentId" id="departmentId"
                    [optionHeight]="25" label="Department"></mdb-select>

departments -- is a regular array of Department object populated inside the ts file.

Dear @1001albertpadilla

Do you mean this effect?:

HTML

 <mdb-select
        (ngModelChange)="getSelectedValue($event)"
        [(ngModel)]="selectedValue"
        [options]="dateOptionsSelect"
        [label]="getLabel() ? '*Department' : 'Department'"
      ></mdb-select>

TS

  selected = '';
  dateOptionsSelect = [
    { value: '1', label: 'Today' },
    { value: '2', label: 'Yesterday' },
    { value: '3', label: 'Last 7 days' },
    { value: '4', label: 'Last 30 days' },
    { value: '5', label: 'Last week' },
    { value: '6', label: 'Last month' },
  ];

  getSelectedValue(event: any) {
    this.selected = event;
  }
  getLabel() {
    if (this.selected === '') {
      return true;
    } else {
      return false;
    }
  }

Hope it helps!

Best Regards, Bartosz.

I did some simplifications. But the general solution works! Thanks!
