Devuelve la ruta dividida si existe el atributo JSON; de lo contrario, devuelve en blanco
Necesito mostrar el nombre y la ruta dividida de la ruta ingresada dinámicamente por un usuario. Para eso, había dividido el camino ingresado por el usuario y solo tomé cierta parte de él. Por ej. si el usuario ingresa la ruta como:
/content/mypath/myfolder/about/images/abc.jpg Luego estoy mostrando images / abc.jpg.
Sin embargo, supongamos que algunos de los usuarios no tienen una imagen, al menos el nombre debe aplicarse y mostrarse en ese caso.
Verifique la función refreshDisplay () para más detalles. Pero arroja un error: Error de tipo no capturado: no se puede leer la propiedad 'coincidencia' de indefinido
¿Cómo puedo solucionar esto?
