如何在 md-dialog 上叠加 md-dialog

How can I superpose an md-dialog on md-dialog

我试图从一个打开的 md-dialog 中打开一个 md-dialog,但问题是当第二个 md-dialog 打开时第一个 md-dialog 关闭了

// the controller of the first popUp 
class popUpOneController{
      constructor($mdDialog){
      this.$mdDialog=$mdDialog;
       .
       .
       .
       } 
  others methods codes......
// the second $mdDialog to be opened from the  first 
// this function will be executed by clicking  on a html  button
  openPopUp2(){
      // here we call a component into the $mdDialog
      this.$mdDialog.show({
            template: '<interlo-sibel  data-to-pass='+data+'  index-selectedElm='+index+' type='+type+' ></interlo-sibel>',
            targetEvent: event,
            escapeToClose: false

        })
   } 
   popUpOneController.$inject=['$mdDialog'];


 export default popUpOneController

我找到了答案,我们刚刚添加了以下属性'skipHide: true'

 openPopUp2(){
      // here we call a component into the $mdDialog
      this.$mdDialog.show({
            template: '<interlo-sibel  data-to-pass='+data+'  index-selectedElm='+index+' type='+type+' ></interlo-sibel>',
            targetEvent: event,
            skipHide: true


        })
   }
