>From time to other, I find myself needing to manipulate the
query-string of URLs in javascript. I have put together the following
function. Is this general enough to put into mk?
extendURL = function(url, parameters) {
var parts = url.split(/\?/);
var base = parts[0];
var args = update(isUndefinedOrNull(parts[1]) ? {} :
parseQueryString(parts[1]), parameters);
var args2 = {};
for (key in args) {
if (!isUndefinedOrNull(args[key])) {
args2[key] = args[key];
}
}
if (keys(args2).length == 0) {
return base;
}
return base + "?" + queryString(args2);
}
assert("foobar?zim=cux&salla=bim" == extendURL("foobar?zim=cux",
{salla: "bim"}));
assert("foobar" == extendURL("foobar?zim=cux", {zim: null}));
assert("foobar?salla=bim" == extendURL("foobar?zim=cux", {zim: null,
salla: "bim"}));
