How do I detect an iPhone user coming to my site?

var agent=navigator.userAgent.toLowerCase();
var is_iphone = ((agent.indexOf('iPhone')!=-1);
if (is_iphone) { conditional code goes here }

I think you might want to do indexOf('iphone') since agent is all lower case.

Windows XP is the same as Windows NT 5.1!

It's the same thing as you said about Firefox being called Mozilla 5.0

Dave,

Thank you for this info.

I have been trying to use the Javascript you listed here to redirect iphone users to a different version of a site, with no luck.

How would you do it if you had to use javascript?

Ruby on rails has auto detection for various types of request:

respond_to do |format|
format.html #index.html.erb
format.xml { render :xml => @articles.to_xml }
format.rss { render :layout => false } #index.rss.builder
format.iphone do #action.iphone.erb
render :layout => false
end
end

Hey Guys,

The javascript in his post is a bit broken, here is the fixed code:

var agent=navigator.userAgent.toLowerCase();
var is_iphone = (agent.indexOf('iphone')!=-1);
if (is_iphone) { /* execution here */ }

Hello,

I am trying to implement your javascript into my site for a page redirection when the user visits the site with a Iphone but i am experiencing problems i was hoping that you could help me by telling me what i did wrong for the javascript coding.

var agent=navigator.userAgent.toLowerCase();
var is_iphone = (agent.indexOf('iphone')!=-1);
if (is_iphone) { scr="http://www.qualitycontactsolutions.com/iphone/" }

Michael -

I think you need to use window.location for your redirect:

var agent=navigator.userAgent.toLowerCase();
var is_iphone = (agent.indexOf('iphone')!=-1);
if (is_iphone) { window.location ="http://www.qualitycontactsolutions.com/iphone/" }

<script language=javascript>
<!--
if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)))
{
location.replace("iphone-version.html");
}
-->
</script>

Miki, that worked. Thanks.

I have created a website using iWeb. I would like to insert some html code (or some type of code) that recognizes when a viewer is visiting on an iPhone versus a regular computer. I've read the above and tried inserting the java script in the html snippet but it does not work. Do you know if there is a way to do this?

Thanks,
Tom Fawbush

you can also use a more advanced web service such as handsetdetection.com which returns real time information on which devices are accessing your site - and then allowing you to adjust the view. Data it returns includes screensize, browser, phone make and model and also location based information.
