Using JS to add to URL's displayed onscreen

Hey,

I am writing a Grease Monkey script that rewrites url's. I need it to take the url's displayed on screen and add ?XX=XXXXXXX to the middle/end of the url's

This is what I am going off of (An existing GM script but I need to modify it because I don't want to replace anything I just want to add a string to the middle or end.)

var link;

link = document.body.getElementsByTagName("a")

for (var i = 0; i < link.length; i++) {
     link[i].href = link[i].href.replace(/php\/movies.php\?file=/,'')
}

Code (markup):

If anybody has any ideas they would be greatly appreciate!

Thanks in advance,
Jeffrey

 

What does it mean to the middle? This way you can add your string to the end:
