Element: msContentZoom event - Web APIs 编辑

Non-standard

This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The msContentZoom event fires when a user zooms the element (changes the scale of the content).

It is a proprietary event specific to Microsoft Edge and Internet Explorer.

Zoomed elements can expose their zoom level through msContentZoom (ie. scrollTop/Left). The zoom level can be reset with Element.msZoomTo().

Example

  contentZoom.addEventListener("MSContentZoom", function(e) {
     zoomFactor.value = contentZoom.msContentZoomFactor.toFixed(2);
  });
