如何防止在Vue/Vuetify应用中缩放传单地图的大小 [英] How to prevent Leaflet map resizing on zoom in Vue/Vuetify app

问题描述

在使用Vuetify框架的Vue.js应用程序中，Leaflet映射出现问题.

I'm having a problem with a Leaflet map in a Vue.js application using the Vuetify framework.

我试图使地图占据全屏(顶部导航栏除外)，但是当我单击缩放按钮时，地图会在页面内垂直调整自身大小/位置.

I'm trying to get the map to occupy the full screen (except for the top nav bar) but the map resizes/repositions itself vertically within the page when I click on the zoom buttons.

这是来自JSFiddle的两个相同问题的屏幕快照，显示在前面:

Here are two screenshots of the same problem from a JSFiddle, showing before:

及之后(请注意地图的向上移动，将导航按钮的一部分隐藏在导航栏下方):

and after (note the upwards shift of the map, hiding part of the zoom buttons below the navbar):

据我所知，之所以出现此问题，是因为Vuetify框架在地图容器元素的顶部放置了填充，并将其(正确地)放置在导航栏下方.但是，当单击+/-缩放按钮时，此填充似乎消失，地图向上移动.但是，我不知道为什么填充会这样消失(假设这是实际问题).

As far as I can tell, the problem is occurring because the Vuetify framework puts padding on the top of the map container element, positioning it (correctly) below the navbar. However, when the +/- zoom buttons are clicked, this padding seems to vanish and the map shifts upwards. However, I have no idea why padding would disappear like this (assuming that this is the actual problem).

如果地图的尺寸​​大大小于页面的高度(例如，高度:85％；在我的完整应用程序中)，则不会发生此问题.有趣的是，我只会在Chrome的小提琴中遇到这个问题.在Firefox中，地图保持其原始位置.

This problem doesn't occur if the map is made significantly less than the height of the page (e.g. height: 85%; in my full application). Interestingly, I only get this problem in the Fiddle in Chrome. In Firefox the map stays in its original position.

我已使用以下代码在 JSFiddle 中复制了该问题:

I've replicated the problem in JSFiddle using this code:

JavaScript:

Javascript:

new Vue({
  el: '#app',
  data: () => ({
    map: null,
    tileLayer: null
  }),
  mounted: function(){
    this.map = L.map('map').setView([38.864720, -77.088544], 12);
    this.tileLayer = L.tileLayer( 'https://cartodb-basemaps-{s}.global.ssl.fastly.net/rastertiles/voyager/{z}/{x}/{y}.png',
      {
        maxZoom: 18,
      });
    this.tileLayer.addTo(this.map);
  }
})

HTML:

<div id="app">
  <v-app id="map-example">

    <v-toolbar color="indigo" dark fixed app style="z-index: 1000;">
      <v-toolbar-title>Application</v-toolbar-title>
    </v-toolbar>
    <v-content>
      <v-container fluid>
        <v-layout>
          <div id="map">

          </div>
        </v-layout>
      </v-container>
    </v-content>
  </v-app>
</div>

CSS:

body {
  margin: 0;
  padding: 0
}
.container {
  padding: 0;
  width: 100%;
  margin: 0;
}
#map {
  height: 500px;
  width: 100%;
  z-index: 100;
}

单击缩放按钮时，小提琴(和我的实际应用程序)中的地图在导航栏下向上跳转.如何使它保持静止并占据导航栏下方的整个窗口?

The map in the Fiddle (and my actual application) jumps upwards under the navbar when the zoom buttons are clicked. How do I get it to stay still, and occupy the entire window below the navbar?

推荐答案

可能与传单有关问题#4125

针对此Chrome特定行为的建议解决方法是防止Leaflet聚焦地图:

Proposed workaround to this Chrome specific behaviour is to prevent Leaflet from focusing the map:

L.Control.include({
  _refocusOnMap: L.Util.falseFn // Do nothing.
});
