[英]Rails Leaflet Webpack blank page
這是@rossta 修復部分相關問題的延續,但現在問題已轉移,所以我想我會重新開始。
沒有錯誤並且腳本正在完成(通過腳本中的 console.log 輸出驗證)。 body 元素出現。 這適用於 gem 傳單,現在在 Rails 5.2 中使用 webpack,但現在在使用 webpack 的 Rails 6 中不行
我把腳本移到頁面中隔離問題map/index.html.erb
<p id="notice"><%= notice %></p>
<% provide(:title, 'Map') %>
<h4>This is map/index.html.erb and is put in layouts/map.html.erb.</h4>
<div id="map_two" class="map clearfix"></div> -->
<script>
function makeMapTwo() {
console.log('Hello from makeMapTwo in map/index.html.erb')
var mapVar = L.map("map_two", { center: [34.040951, -118.258579], zoom: 13 });
L.tileLayer('https://crores.s3.amazonaws.com/tiles/bkm/{z}/{x}/{y}.png').addTo(mapVar);
$.getJSON("line_data.geojson", function (data_data) {
var timelineData = L.timeline(data_data, {
style: function(data_data){
return {
stroke: true,
fillOpacity: 0.5
}
}, // end style: function(data_data)
waitToUpdateMap: true,
onEachFeature: function(data_data, layer) {
layer.bindTooltip(data_data.properties.popup, { direction: 'top' } );
} // onEachFeature:
}); // end let timelineData = L.timeline
var timelineControl = L.timelineSliderControl({
enableKeyboardControls: true,
steps: 100,
start: 1885,
end: 1928,
});
timelineData.addTo(mapVar);
timelineControl.addTo(mapVar);
timelineControl.addTimelines(timelineData);
}); // end $.getJSON
}; // end function makeMapTwo()
$(document).ready(function() {
makeMapTwo();
});
</script>

和app/javascript/packs/application.js

window.jQuery = $
window.$ = $

config/webpack/environment.js
:
const { environment } = require('@rails/webpacker')
const webpack = require('webpack')
environment.plugins.append('Provide',
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
jquery: 'jquery',
Popper: ['popper.js' ,'default'],
}))
module.exports = environment
package.json
const { environment } = require('@rails/webpacker')
const webpack = require('webpack')
environment.plugins.append('Provide',
new webpack.ProvidePlugin({
$: 'jquery',
jQuery: 'jquery',
jquery: 'jquery',
Popper: ['popper.js' ,'default'],
}))
module.exports = environment
需要調試,但我不知道從哪里開始。
我不敢相信這種變化有任何影響,但確實如此。
將<div id="map_two"...
var mapVar = L.map("map_two"...
為僅map
並加載。我使用的是 map_two 因為當我之前進行實驗時,我認為這兩個頁面我只是使用map
感到困惑。我也嘗試了map-two
並且它也不起作用(不是我所期望的,但我仍然不明白發生了什么。我在更改之間重新啟動了服務器更加確定發生了什么。
