juAx methods

<static> is(browser[, matchKey, userAgent])

Verifies browser information.
Parameters: String browser, RegExp matchKey, String userAgent
Returns: Boolean

if (juAx.is('firefox lt 3')) {
    document.write("this firefox is older than version 3");
}

Parameters description

browser

browser parameter is composed of 3 elements:

# the name of the browser
# an operator to compare the versions
# the version we want to compare

Both name of the browser and version can be found in the userAgent string provided by browser.
For example, the newers Firefox userAgent string looks like this: Mozilla/5.0 (Windows; U; Windows NT 6.1; en-GB; rv:1.9.1.4) Gecko/20091016 Firefox/3.5.4

Thus, the name of the browser becomes a lowercase string, signifying the browser’s real name in the userAgent string.

For the operator we decided to use the batch like  form, so we got to this types of operators

eq / equal
neq / not equa l
gt / greater than
gte / greater than or equal to
lt / lower than
lte / lower than or equal to

For the version we stoped at the first to components from the versioning convention: the version and the subversion.

if (juAx.is('firefox')) {
// this tests ONLY if the browser is firefox
}
if (juAx.is('firefox eq 3.0')) {
// this tests if the Firefox browser's version is exactly 3.0
}
if (juAx.is('firefox gte 2.5')) {
// this tests if the Firefox browser's version is greater than
// or eaqual to 2.5
}

matchKey

Since we cannot cover all the browsers in the world, we had to create a convetion. If we can’t obtain the browser’s version ourselves, we tell the user how to get it. The matchKey variable is a regluar expression ment to tell the is function how to obtain information about the browser’s version.

For example, let’s say, that the Konqueror (KDE Linux) browser was not added in our list already, and you will have to create a regular expression to get the info for us. We 1st look into a useragent database like http://www.useragentstring.com and notice that Konqueror’s user agent .
i.e.
Mozilla/5.0 (compatible; Konqueror/4.2; Linux; X11; x86_64) KHTML/4.2.4 (like Gecko) Fedora/4.2.4-2.fc11
After seing how the version model is set into the user agent we came up with the next regular expression:

if (juAx.is('konqueror gt 3', /konqueror\/([0-9]+\.?[0-9]*)/i)) {
// this tests Konqueror browsers for versions greater than 3.0
}

The group we created in the regular expression ( /konqueror\/([0-9]+\.?[0-9]*)/i ) will be able to tell the is function the browser’s version.

userAgent

User agent parameter is nothing but a dummy variable for test. It replaces the userAgent memorized by juAx with a userAgent string of your choice.
For example

if (juAx.is(
    'konqueror gt 3',
    /konqueror\/([0-9]+\.?[0-9]*)/i,
    'Mozilla/5.0 (compatible; Konqueror/4.2; Linux; X11; x86_64) \
KHTML/4.2.4 (like Gecko) Fedora/4.2.4-2.fc11')) {
// this tests Konqueror browsers for versions greater than 3.0
}
