Just a small suggestion....
Maybe wrap the innerHTML with encodeURI(), or replace / escape quotes, otherwise if there is a quote in the HTML, it will break the title attribute.

Question
Adding title attribute to href tag
I'm found a small JavaScript script that allows a user to create a HREF by selecting text string from a textarea and typing in the URL when prompted, but it does not add the title attribute to HREF.
Using PHP:
- It is possible to detect HERF's without a title?
- It is possible to add the title to the HREF?
If 1 & 2 above is yes, then is it possible to set the title of the HREF to the innerHTML of the HREF:
<a href="www.google.com" title="mywebsite name">my website name</a>

You can certainly use the php string functions to search and modify the string with the URL.
For example, to find if a string "title=" exists in a longer string $url, you would use:
if (strpos($url, "title=") === false)
// note, be sure to use THREE ='s in the boolean comparision
// http://us2.php.net/manual/
To find the position of "title=" in a string $url, you would use:
$title_position = strpos($url, "title=");
// http://us2.php.net/manual/
To find the length of any string $url, you would use:
$string_length = strlen($url);
// http://us2.php.net/manual/
To pick out any piece of a string $url at a location you can identify, you would use substr( ):
$url_before_title = substr($url, strpos($url, "title=");
// http://us2.php.net/manual/
To insert "title=xxx" into a string, choose the place you want to insert it, then using strlen( ) and substr( ),
divide the string into $url1 and $url2 at the place you want to insert "title=xxx". Then concatenate the pieces using:
$new_url = $url1 . "title=xxx" . $url2;
These are the main php string functions that can help you check the URL and insert a title into it if there isn't one there already.
Check this code sample:
<html>
<head>
<title>Script Demo Gops</title>
<script type="text/javascript">
window.onload=function(){
var urls=document.links;
for(var i=0;i<urls.length;i++){
var titl=urls[i].getAttribute(
if(trim(titl).length==0) urls[i].title="Go to "+ urls[i].innerHTML;
}
}
function trim(str){
return str.replace(/(^\s+|\s+$)/g
}
</script>
</head>
<body>
<a href="#">Page1.com</a><br>
<a href="#">Page2.com</a><br>
<a href="#" title="Go to Page3">Page3.com</a><br>
<a href="#">Page4.com</a><br>
<a href="#">Page5.com</a><br>
<a href="#">Page6.com</a><br>
</body>
</html>
Still u can use my solution:
<html>
<head>
<title>Script Demo Gops</title>
<script type="text/javascript">
window.onload=function(){
var urls=document.links;
for(var i=0;i<urls.length;i++){
var titl=urls[i].getAttribute(
if(trim(titl).length==0) urls[i].title="Go to "+ urls[i].innerHTML;
}
}
function trim(str){
return str.replace(/(^\s+|\s+$)/g
}
</script>
</head>
<body>
<a href="#" title="">Page1.com</a><br>
<a href="#" title="">Page2.com</a><br>
<a href="#" title="Go to Page3">Page3.com</a><br>
<a href="#" title="">Page4.com</a><br>
<a href="#" title="">Page5.com</a><br>
<a href="#" title="">Page6.com</a><br>
</body>
</html>
gops,
Your solution does not add the title attribute to the end of the href tag.
I phyiscally want to add it. Take this example below:
<a href="http://www.domain.co
This is the url in my string before i insert it into the DB.
after i append the title attribute to the href tag, it should look like:
<a href="http://www.domain.co

Well probably you could just walk through to document.links collection and test/set titles:
for(var i = 0; i < document.links.length; i++) {
if(!document.links[i].titl
document.links[i].title = "Visit " + document.links[i].innerHTM
}
}
