The pop-up box component below is encapsulated using classes. A pop-up component is generated by using a new instance. This article mainly introduces in detail the method of encapsulating pop-up window components with js classes. It has certain reference value. Interested friends can refer to it. I hope it can help everyone.

The code is directly below:

html structure:

    $.extend(opt,option);

    //特权方法：1、open()；2、close()；3、setPrize（）；4、setContent（）控制弹窗内显示的内容
    this.open=function(){

      mask.show();
    };
    this.close=function(callbalck){
      wrap.hide();
      mask.hide();

    this.setPrize=function(text){

    this.setContent = function (text) {
