getHttpValue(name: String): String;
The getHttpValue method of the JadeHTMLClass class processes the httpString property value and returns the value of the string specified in the name parameter with the HTTP character encoding removed from it; that is, any "+" characters are changed to space characters and any hexadecimal-encoded characters ("%xx") are decoded to the original characters. For example, if the value of the httpString property is "...&inventor=Wilbur+%26+Orville+Wright&...", getHttpValue("inventor") returns "Wilbur & Orville Wright".
