Constructor Detail

IFrame

public IFrame()

Creates a new iframe.

IFrame

public IFrame(String src)

Creates a new iframe with a source URL.

Parameters:

src - Source URL

Throws:

IllegalArgumentException - if src uses a scheme that is not considered safe according to DeploymentConfiguration.getUrlSafeSchemes(); see setUnsafeSrc(String) and the configuration property

Method Detail

setSrc

public void setSrc(String src)

Sets the source of the iframe.

Parameters:

src - Source URL.

IllegalArgumentException - if the URL uses a scheme that is not considered safe according to DeploymentConfiguration.getUrlSafeSchemes(); see setUnsafeSrc(String) and the configuration property

setUnsafeSrc

public void setUnsafeSrc(String src)

Sets the source of the iframe without validating its scheme.

Unlike setSrc(String), this method does not reject URLs based on the configuration. Use it only for URLs that are fully under your control and known to be safe, such as a hard-coded javascript: or data: URL. Passing untrusted input here can expose the application to cross-site scripting (XSS) attacks.
