Incrustar un R htmlwidget en la página web existente (1)
El htmlwidget htmlwidget ofrece una forma de guardar las piezas para el widget por separado de la siguiente manera:
library(dygraphs)
d1 <- dygraph(nhtemp, main = "New Haven Temperatures") %>%
dyRangeSelector(dateWindow = c("1920-01-01", "1960-01-01"))
saveWidget(d1, file = "widget_file.html", selfcontained = FALSE)
Lo que resulta en los siguientes archivos / dirs:
widget_file.html
widget_file_files
/dygraphs-1.1.1
..
/dygraphs-binding-0.6
..
/htmlwidgets-0.5
..
/jquery-1.11.1
..
/moment-2.8.4
..
/moment-timezone-0.2.5
..
Y widget_file.html lee como sigue:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
<script src="widget_file_files/htmlwidgets-0.5/htmlwidgets.js"></script>
...
<script src="widget_file_files/dygraphs-binding-0.6/dygraphs.js"></script>
</head>
<body style="background-color:white;">
<div id="htmlwidget_container">
<div id="htmlwidget-2956" style="width:960px;height:500px;" class="dygraphs"></div>
</div>
<!-- THE JSON DATA -->
<script type="application/json" data-for="htmlwidget-2956">
{THE JSON DATA YOU WERE LOOKING FOR}
</script>
<!-- THE JSON DATA -->
<script type="application/htmlwidget-sizing" data-for="htmlwidget-2956">{Widget-Styling-Json}
</script>
</body>
</html>
Para que pueda editar su html de la siguiente manera:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
<!-- Begin of scripts to run the widget -->
<script src="widget_file_files/htmlwidgets-0.5/htmlwidgets.js"></script>

Esto te dejará con los datos json codificados en el documento html (ver mi). Si desea cargar los datos dinámicamente puede utilizar, por ejemplo,
json_dat <- readLines("widget_file.html")[18]
cat(sub("</script>","",sub(''<script type=/"application/json/" data-for=.*/">'', "", json_dat)), file = "./widget_file_files/my_data.json")
Para guardar los datos de json como ./widget_file_files/my_data.json y luego cargarlo dentro del html. Si estás usando PHP puedes hacer:
<script type="application/json" data-for="htmlwidget-2956">
<?php include(''widget_file_files/my_data.json''); ?>
</script>
Si desea utilizar una solución JS pura, quizás visite http://api.jquery.com/jquery.getjson/ y el widget_file_files/htmlwidgets-0.5/htmlwidgets.js cómo los datos json están enlazados momento...
PD: como esta pregunta ya tenía mucha atención, también podría ponerse en contacto con el desarrollador del paquete y pedirle que " htmlwidgets:::saveWidget " de la opción "autocontenida" en htmlwidgets:::saveWidget : que significa guardar los datos json por separado e incluir por ejemplo, a través de jquery.getjson
Estoy tratando de incrustar un R htmlwidget en una página web existente, una página web que ya tiene bootstrap y estilo aplicado. Por ejemplo, considere la siguiente página web (observe dónde se debe colocar el widget):
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Document</title>
</head>
<body>
<p>This is a test.</p>
<!-- htmlwidget should go here. -->
<p>A closing paragraph.</p>
</body>
</html>
Puedo crear y guardar un widget de datos como el siguiente:
library(htmlwidgets)
library(datatable)
d1 <- datatable(mtcars, filter = "top")
saveWidget(d1, file = "widget_file.html")
El widget_file.html generado (incluso para este modesto widget) contiene una gran cantidad de código. ¿Hay una manera fácil de incrustar esto en una página web / plantilla existente?
He tenido éxito al usar <iframe src="widget_file.html"> pero me pregunto si hay una mejor manera. Además, ¿hay una manera de separar piezas / dependencias (por ejemplo, datos de widget_file.html ) del widget_file.html para que puedan colocarse en otras carpetas?
Nota: creé la etiqueta htmlwidget , pero creo que también debería haber una etiqueta htmlwidgets .
