    Properties

    Parts of this page show the use of the XPInstall API. The majority of this API is now deprecated and as of Gecko 1.9 no longer available. Extension, Theme, and plug-in developers must switch away from install.js based packages to the new packaging scheme with an install.rdf manifest. In particular plugin developers should see how to package a plugin as an extension.

    Properties

    archive
    Full local path of the archive after it is downloaded to the platform specific temp folder. (e.g. C:\TEMP\argstest.xpi)
    arguments
    args can be passed in through the triggering APIs by attaching a ? and then the rg string to the xpi URL: (e.g. startSoftwareUpdate("http://webserver/argstest.xpi?ARGUMENT_STRING") will result in the value of Install.arguments being ARGUMENT_STRING #). Note that spaces in the arg string are legal. Everything after the question mark is treated as one string which becomes the Install.arguments property.
    buildID
    The application build ID in the form 20041231. Note that due to branching (different versions of Gecko with different feature sets might be built on the same day), using this property to "detect" the application version may produce false results. Additionally, the build ID can be 0 for custom builds.
    jarfile
    Alias for archive
    platform
    Contains information about the platform XPInstall was compiled for/runs on. For example, the value could begin with "Windows", "Macintosh" or "X11" (for Unix/Linux). For more details, see the corresponding code living in the GetInstallPlatform method of class nsInstall.
    url
    The fully qualified URL of the xpi (file URL, http URL, ftp URL, etc.) (e.g. http://dolfin/sgehani/zzz/ip.xpi). Note, even if triggered using relative URLs this will show the full URL (after qualification).
