How does JS regular expression ensure that the input is an integer

This article mainly shares with you a method of how to ensure that the input is an integer using JS regular expressions. It has a good reference value and I hope it will be helpful to everyone. Let’s follow the editor and take a look.

<span class="show_total">
  <span class="edit_ifo">{{totalRunTimes}}</span>
  <a class="btn btn-primary edit_btn" (click)="editTotalTimes()">编辑</a>
</span>

editTotalTimes() {
 $('.show_total').addClass("display_none"); 
 $('.edit_total').removeClass("display_none");
//  确保输入的为整数  
$('.total_times').off('input propertychange');  
、('.total_times').on('input propertychange', function() { 
   let v = $(this).val().toString();//获取输入框的数   
    v = v.replace(/\D/g,'');//将除整数的其他字符替换为空    
    $(this).val(v);//返回输入框  
    });
}

In this way, all entered non-digits will be replaced with empty strings.
