encodeURI

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since julio de 2015.

Sumario

Codifica un Identificador de Recurso Uniforme (Uniform Resource Identifier, URI) reemplazando cada instancia de ciertos carácteres por uno, dos o tres secuencias de escape representando el carácter codificado en UTF-8.

In this article

Sintaxis

encodeURI(URI)

Parámetros

URI

Un Identificador de Recurso Uniforme codificado.

Descripción

Se asume que el URI es un URI completo, a fin de no codificar caracteres reservados que tienen un significado especial en la URI.

encodeURI reemplaza todos los caracteres excepto los siguientes con las secuencias de escape UTF-8:

Tipo Incluye
Caracteres reservados ; , / ? : @ & = + $
Caracteres No escape Alfabéticos, dígitos decimales, - _ . ! ~ * ' ( )
Almohadilla #

Tenga en cuenta que encodeURI por sí sola no puede formar solicitudes correctas HTTP GET y POST, como por XMLHTTPRequests, porque "&", "+", y "=" no están codificados, los cuales son tratados como caracteres especiales en las solicitudes GET y POST. encodeURIComponent, sin embargo, codifica estos caracteres. Lo más probable es que estos comportamientos no sean compatibles en los navegadores Web.
