If JavaScript™ is specified as the response format, the reply data is formatted to be parsed as a JavaScript™ include file.
A typical JavaScript™ properties response has this general structure:
<varname>
objectName.propertyName
</varname>='
<varname>
propertyValue
</varname>'
...
propertyValue
can be empty. White space is optional at the beginning and end of each line and before and after the = separator. All values are enclosed by single quotes. Single quotes in strings are escaped with two consecutive single quotes.
To parse a JavaScript™ properties response, any object or objects referenced in the response must be created before the properties file is loaded. Following is an example for using req=props
to obtain the response image size in JavaScript™:
<script> image = new Object; </script>
<script
src='http://myServer/is/image/myImage?req=props,javascript'>
<script> alert("Size: " + image.width + " , " +
image.height); </script>
