Question

我想将输入类型值转换为逗号分隔数。例如，在我的.html文件中，我的净工资输入值是35000（我在Formbuilder中设置）。如果我键入任何值（例如，＆gt;输入= 65000，预期输出=> 65,000）。那么我想在打字稿中做的所有事情。请帮助我。

<div class="form-group md-form mob selecticon rupee-icon" [ngClass]="{'has-danger':!loanApplyForm.controls['netsalary'].valid && loanApplyForm.controls['netsalary'].touched}">
                                    <label for="netsalary">Net Monthly Salary <span class="asterisk">*</span></label>
                                    <div *ngIf="loanApplyForm.controls['netsalary'].invalid" class="alert-change">*Please enter the monthly salary.</div>
                                    <input (focus)="loanApplyForm.controls['netsalary'].reset()"  class="form-control emi-input" id="netsalary" [formControl]="loanApplyForm.controls['netsalary']"  type="number">
       </div>

这是我的.html文件

在.html尝试此代码并将数字转换为逗号分隔值。

<input (focus)="loanApplyForm.controls['netsalary'].reset()"  class="form-control emi-input" id="netsalary" [formControl]="numberToCommaSeperate(loanApplyForm.controls['netsalary'])"  type="number">

并.ts添加此功能

numberToCommaSeperate(num) {
  return num.toString().replace(/\B(?=(\d{3})+(?!\d))/g, ",");
}

Angular4将输入数转换为逗号分隔值？
