I guess you do have a lot of filtering to do! I'm probably not one that
can be of much help. Your plugin is obviously going to be performance
critical with as much filtering you'll need to do. I'm still learning
about performance factors of various functions ,methods, memory usage
etc

Hello Charlie,
thank you for responding that fast.
I am trying to push my plugin l10n (http://cms4j.wordpress.com/l10n-a-
jquery-plugin/) a bit further so that is does not only localize texts
within the <span> elements, but also any element in a web page.
Therefore i loop through all elements that have a class of "l10n" like
this:
$(".l10n").l10n({options});
Within the plugin in the method
return this.each(function() {
// do the cool stuff
});
i have to decide what kind of element i am dealing with. Therefore i
need the checks for the type of element.
Hope that made things clearer and also hoping for your answer.

when you are looping through all these tags what are you trying to do? exclude certain tags or find them to manipulate?
if trying to exclude you can do things like
$(".specificClass *").not("img").hide() //hides all tags inside .specificClass except img's
$(".specificClass *").find("img").hide()// hides only img's within .specificClass
the need to check each element individually is probably not necessary and chances are you are under utilizing the power of jquery to do what you want.
Here's an example:
you are using this if statment:
if ($("selector").is(":button")) {
// do something
}
except it is very likely not necessary to test with if on every selector. If you do something like $(".specificClass button").css("color","red"); either this button is found within the class and color is made red,...... or no such element is found *and* nothing happens! no error, no failure of jquery
perhaps throwing a few tasks up on this board that you are trying to accomplish would help, then see that some may be extremely easy to accomplish with not a lot of code
cms4j wrote:Hello there, i have a couple of elements on my web page, that i want to manipulate in one loop. jQuery.each($(".specificClass"), function(i) { // do something } Within that loop i have to check what type of element that very one is e.g. a <div> or a <span> or an <img> or a <input type="button"> or something else. I managed to isolate some of them, the easiest was the button where i checked the following: if ($("selector").is(":button")) { // do something } In the jQuery API 1.3.2 there are some more useful Forms Filters like :input, :text, :checkbox etc. What i really miss is something for adropdownlist. I would have expected that there is something like if ($("selector").is(":select")) { // do something } but i could not find it. It would also be great to have something to check if the element is an image. I have read that there exist such a check, but that is for images that are input-images within a form. I am longing for a simple check
for an image somewhere in the web page. At the moment i build workarounds like this, but that is not really satisfying... if ( !isNullOrEmpty($("selector").attr("src"))) { // --- image --- // do something } if ($("selector")[0].selectedIndex >= 0) { // ---dropdownlist--- // do something } // convenience function like the one in C# window.isNullOrEmpty = function(obj) { return (obj === '' || obj === null || obj === undefined) }
