stringByEvaluatingJavaScriptFromString, finding specific input tags

Question

I've loaded a webpage into my UIWebView and the page contains a number of input tags. I want to identify the one that looks like:

<input name="j_username" type="text" tabindex="1" />

Do you know what I would write in stringByEvaluatingJavaScriptFromString?

Thanks!

What do you mean identify? document.querySelector("input[name=j_username]")? — Esailija

I would use document.getElementsByName:

NSString* jsString = @"var myElement = document.getElementsByName(\"j_username\")[0];";
[theWebView stringByEvaluatingJavaScriptFromString:jsString];
