I'm trying to apply a JavaScript function only to browsers that support iframes. Currently, I am working with this: function into_frame() { var uagent = navigator.userAgent.toLowerCase(); if (uagent.search("palm") == -1) { if (top.location == location) { var str1, str2; str1 = location.href; str2 = str1.replace ("&", "andandand"); top.location.href = "http://asurfc.com/forum.php?iframe=" + str2; } } } In this case, I don't run the JavaScript when the user agent indicates the site is open on a Palm device (which doesn't support iframes). I would like to check for other words in the useragent string and thought I could do that by using search("palm"|"word2"|"word3") but this doesn't work. How would I go about checkign if any of many possible words are in the useragent string? -Ryan Adams Free Computer Tips and more:http://RyanTAdams.com Paid Tech Support: Black Diamond

Create an array of blocked user agents and then loop through & it test each against the user agent? something like: var no_iframe_ua = new Array('palm','word1','word2'); var iframe_support = true; var uagent = navigator.userAgent.toLowerCase(); for (c=0; c<= (no_iframe_ua.length -1); c++) { if (uagent.search(no_iframe_ua[c]) != -1) { iframe_support = false; break; } } if (iframe_support == true) { //IFrame code } else { //No iframe code } (I didn't test this code - could be a syntax error in there somewhere)

I suppose that would work. Why doesn't using the | character between words in the search() function work though? -Ryan Adams Free Computer Tips and more:http://RyanTAdams.com Paid Tech Support: Black Diamond

Err, good point. Try: search(/palm|word2|word3/)

I ended up using if (uagent.search(/"palm"|"windows ce"|"winmobile"/) == -1) which seems to work. Looks like it needs the forward slashes and quotes. -Ryan Adams Free Computer Tips and more:http://RyanTAdams.com Paid Tech Support: Black Diamond
