get the tags i want.. efficiently

[theS70RM]

Hey,

im using getElementsBytagName...

foo = document.body.getElementsByTagName("div")

But say i want to get all the divs and all the td tags, or any number of specified tags, and store them in the one variable...

What would be the most efficient way to do this?

can you do this:

foo = document.body.getElementsByTagName("div")
foo += document.body.getElementsByTagName("span")
foo += document.body.getElementsByTagName("td")

????

probably not i think


Cheers

You could try using getElementsByTagNames() (note the 's').

[rnd me]

with a little overhead, you could code it quite simply.

library: tags (gets a true array of tag names)

function tags(elm, tid) {function obValsl(ob) {try {if (ob && ob.length) {var r = [], i = 0, mx = ob.length;for (var z = 0; z < mx; z++) {r[z] = ob[z] || undefined;}}} catch (yy) {alert(yy);}return r;}
if (tid) {if (elm.split) {elm = el(elm);}return obValsl(elm.getElementsByTagName(tid));}return obValsl(document.getElementsByTagName(elm));};
 
//then you code is simple:
myTags = tags("div").concat(tags("span")).concat(tags("td"));
