Hi All,

var FLG;
var art_extn = ["psd","tif","eps","jpg","ai","pdf"];

FLG = 0;
for(var a=0;a<art_extn.length;a++){

    var patt = /\."+art_extn+"$/i;
    alert(art_extn +"\n\n"+patt);
    if(linkname.match(patt) != null){
        alert("match");
        FLG = 1;
    }
}

if(FLG == 0){

or something like…

var linkname = "0012.picture.eps";

var res = linkname.match(/\.(psd|tif|eps|jpg|ai|pdf)$/i)
alert(res[1]);
res != null ? res = true : res = false;
alert(res);

That's indeed much better...

From you Peter 'thanks' it was however flawed…

var linkname = "0012.picture.tif";

var res = linkname.match(/\.(psd|tif|eps|jpg|ai|pdf)$/i)
if(res != null) alert(res[1]);
res != null ? res = true : res = false;
alert(res);

alerting 'res[1]' would fail if there was no match… but I was just trying show what it matched if needed… I think this may be better now…

You can't use variables in a literal regex. try something like this:

patt = RegExp ("\\." + art_extn + "$", "i");
. . .
. . .
if (linkname.match (patt) != null)
