Extracting the
Query String of an URL: getQuery() Function
The
getQuery() function helps
us extract the query string of an URL. Its syntax is:
URL.getQuery(url);
If
there is no query string in url,
getQuery() returns an
empty string. If any error occurs, getQuery()
returns invalid. For
example, if url is not
an URL or if the syntax of url
is not correct, invalid
is returned.
The
following WMLScript example demonstrates the use of the getQuery()
function:
w
= URL.getQuery("http://www.developershome.com/");
x =
URL.getQuery("http://www.developershome.com/tutorial_eg.asp?q1=abc&q2=123");
y
= URL.getQuery("tutorial_eg.asp?q1=abc&q2=123");
z
= URL.getQuery("tutorial_eg.asp?q1=abc&q2=123#card1");
After
the execution of the above WMLScript code, w
contains an empty string while x,
y and z
have the string value "q1=abc&q2=123".
