如何在 Ionic 2 中定位弹出框

Looking through the code, there doesn't seem to be an option for the popover's position. However, when opening the popover as a result of the user tapping something, it can be positioned by the click event. We can use that knowledge for manual positioning as well:

let pop = this.popoverCtrl.create(MyPopover);

let ev = {
  target : {
    getBoundingClientRect : () => {
      return {
        top: 100
      };
    }
  }
};

pop.present({ev});

需要注意的几点:

• 您可以设置 top、left 或两者的值.
• 值必须以像素为单位，如数字.
• 如果 top 或 left 没有给出，那么通常的定位算法将用于该值.
