■Parameter settings of JavaScript objects
• When an optional parameter setting is omitted, the object will be displayed as default. Also, when the optional parameter
setting is abnormal, the object will be displayed as default.
• Set parameters using the specified data formats. A parameter error occurs if a parameter is set in the data format other
than the specified one (for example, when a character string such as '1' is set in the parameter that should be a numeric
value).
• If the X- and Y- coordinates are omitted, the object will be placed at the upper left end (coordinates 0, 0).
• For an RGB value specified for parameters or HTML specifications such as a color name, the range check is not
performed. The operation for an abnormal setting differs depending on the browser.
• When specifying a device name which includes \, such as Un\G and Jn\X, repeat \ as Un\\G and Jn\\X. (\ is an escape
sequence.)
• The following table lists formats and positional notations available for the devices which can be set for JavaScript objects.
