Si tu biblioteca de documentos funciona perfectamente en su propia p\u00e1gina, pero los botones Descargar<\/strong> (y a veces Vista previa<\/strong>) no hacen nada una vez que la insertas en otro sitio web, este art\u00edculo explica por qu\u00e9 y qu\u00e9 hacer al respecto.<\/p>\n

Qu\u00e9 est\u00e1 pasando<\/h2>\n

Algunas plataformas de sitios web cargan el contenido insertado dentro de un sandbox<\/em> iframe, que es un contenedor aislado al que el navegador web impide deliberadamente realizar ciertas acciones, incluida la descarga de archivos. Cuando tu biblioteca de documentos se coloca dentro de uno de estos espacios aislados, el navegador bloquea la descarga sin avisar y el bot\u00f3n parece no hacer nada.<\/p>\n

La vista previa tambi\u00e9n puede verse afectada. De forma predeterminada, la vista previa se abre en una pesta\u00f1a nueva del navegador, y el mismo espacio aislado tambi\u00e9n impide abrir pesta\u00f1as nuevas.<\/p>\n

Esta es una restricci\u00f3n impuesta por la plataforma de alojamiento y aplicada por el navegador. No es un fallo de Document Library Pro. La misma biblioteca se descarga perfectamente desde su propia URL y en cualquier plataforma que no a\u00edsle los elementos insertados.<\/p>\n

Wix<\/strong> es el ejemplo m\u00e1s habitual. Las dos opciones de inserci\u00f3n de Wix (“Embed HTML\/Code” y “Embed a Site”) colocan tu biblioteca en un entorno aislado que no permite descargas.<\/p>\n

C\u00f3mo confirmar que esta es la causa<\/h2>\n

Comprueba esto primero, porque si los s\u00edntomas son distintos puede tratarse de otro problema que s\u00ed podemos<\/em> solucionar:<\/p>\n

    \n
  1. Abre la URL directa de la biblioteca.<\/strong> Copia la direcci\u00f3n de tu Embed Code (por ejemplo https:\/\/your-library.documentlibrary.app\/?dlp_embed=1<\/code>) y \u00e1brela en una pesta\u00f1a nueva del navegador. Haz clic en Descargar. Si ah\u00ed se descarga bien pero insertada no, la causa es la sandbox de inserci\u00f3n.<\/li>\n
  2. Revisa la consola del navegador (opcional, t\u00e9cnico).<\/strong> En la p\u00e1gina insertada, abre la consola de desarrollo del navegador. Un mensaje como \"Download is disallowed. The frame\u2026 is sandboxed and the 'allow-downloads' permission is not set<\/em>\" o ERR_BLOCKED_BY_CLIENT<\/code> lo confirma.<\/li>\n<\/ol>\n

    Si el archivo tambi\u00e9n<\/strong> tampoco se descarga desde la URL directa, este no<\/em> el problema del entorno aislado, as\u00ed que contacta con soporte<\/a> y te ayudaremos a llegar al fondo del asunto.<\/p>\n

    C\u00f3mo solucionarlo<\/h2>\n

    Wix<\/h3>\n

    Instala y usa la app de Wix de Document Library Pro en lugar de pegar un Embed Code. La app a\u00f1ade tu biblioteca como un elemento nativo de Wix que no est\u00e1 aislado, as\u00ed que la descarga y la vista previa funcionan con normalidad. Si has pegado el Embed Code y ves este problema, contacta con soporte<\/a> y te ayudaremos a cambiarte.<\/p>\n

    WordPress autoalojado, Webflow, Framer o sitios HTML sencillos<\/h3>\n

    Estas no a\u00edslan las inserciones, por lo que el c\u00f3digo de inserci\u00f3n est\u00e1ndar funciona, incluidas las descargas. Si ves el problema en una de ellas, se debe a otra cosa, as\u00ed que contacta con soporte<\/a>.<\/p>\n

    Otros creadores de sitios web (Squarespace, Notion y similares)<\/h3>\n

    Si la plataforma ofrece una aplicaci\u00f3n o integraci\u00f3n oficial de Document Library Pro, \u00fasala. Si solo ofrece un campo gen\u00e9rico de “embed code” y a\u00edsla el contenido, no podr\u00e1s activar las descargas en esa plataforma. Aun as\u00ed, puedes permitir que los visitantes vean<\/strong> tus documentos (ver m\u00e1s abajo).<\/p>\n

    Opci\u00f3n de solo lectura (funciona incluso dentro de una sandbox)<\/h3>\n

    Si en tu plataforma no se pueden activar las descargas, tus visitantes a\u00fan pueden abrir y leer los documentos en un visor dentro de la p\u00e1gina. Solo tienes que poner el bot\u00f3n de descarga, en los ajustes de tu biblioteca, en desactivado<\/strong> el bot\u00f3n de descarga en la pesta\u00f1a Display de tus ajustes y deja el Vista previa<\/strong> activado. Dentro de una sandbox, la vista previa abre autom\u00e1ticamente cada documento en un visor dentro de la p\u00e1gina (en lugar de una pesta\u00f1a nueva), as\u00ed que funciona incluso donde las descargas no lo hacen.<\/p>\n

    Esto funciona con PDF e im\u00e1genes<\/strong>. Los archivos de Word y Excel no se pueden mostrar as\u00ed en un navegador, por lo que una configuraci\u00f3n de solo lectura encaja con bibliotecas formadas por PDF e im\u00e1genes. Si quieres ayuda para configurarlo, contacta con soporte<\/a>.<\/p>\n

    \u00bfSigues atascado?<\/h2>\n

    Ponte en contacto a trav\u00e9s del soporte<\/a> indicando el nombre de tu plataforma y la URL de la p\u00e1gina, y te aconsejaremos la mejor opci\u00f3n para tu caso.<\/p>","protected":false},"excerpt":{"rendered":"
