Let me start off by saying I'm very new to scripting languages but so far I love them all and I'm learning multiple new languages right now. I've built a website that is almost all contained in a .js file and although I now understand how dumb that was it would take a much deeper knowledge of html and javascript in order to remake it in a better way.

skip to problem

<script type="text/javascript" src="js/SetAllVarsBlank.js"></script>
<script id='blankjs' type="text/javascript" src="js/blank.js"></script>
<script type="text/javascript" src="js/StringSite.js"></script>

I need to change

<script id='blankjs' type="text/javascript" src="js/blank.js"></script>

to

<script id='blankjs' type="text/javascript" src="js/A_different_js_file.js"></script>

using onclick.

Any help would be greatly appreciated... I've already spent 3 hours looking up how to getElementById only to fail miserably. I'm not an idiot I just know almost no javascript and only have been using it to document.write html code that is repetitive and needs variables.

Sadly you can't use getElementById on script tags since they don't support the ID attribute:
http://www.w3schools.../tag_script.asp

You could do something like so though (I believe):

var scripts = document.getElementsByTagName("SCRIPT");
var blank_js_script = scripts[1];
blank_js_script.src = "http://www.w3schools.com/TAGS/tag_script.asp";

NOTE - Untested code.

Hope that helps.

I really appreciate your help, I tested that a few ways and couldn't get it to work, it has no effect and won't load a js file to any script position. Anyways, I thought that even though it wasn't supported that it would still have a chance of working : \, this is the last thing I need to figure out before my site will be usable. I think I can just contain the .js contents in a variable and then call that variable using a function ... haha, I'm a complete newb, I'm studing though, just paid lynda almost 400 dollars so that I'll be able to use their site for a year, starting college asap when I get out of the military.

Edit- Found a way but there is a problem, scripts afterwards don't take into account variables on .js file being added

function createjscssfile(filename, filetype){
 if (filetype=="js"){ //if filename is a external Javascript file
  var fileref=document.createElement('script')
  fileref.setAttribute("type","text/javascript")
  fileref.setAttribute("src", filename)
 }
 else if (filetype=="css"){ //if filename is an external CSS file
  var fileref=document.createElement("link")
  fileref.setAttribute("rel", "stylesheet")
  fileref.setAttribute("type", "text/css")
  fileref.setAttribute("href", filename)
 }
 return fileref
}

function replacejscssfile(oldfilename, newfilename, filetype){
 var targetelement=(filetype=="js")? "script" : (filetype=="css")? "link" : "none" //determine element type to create nodelist using
 var targetattr=(filetype=="js")? "src" : (filetype=="css")? "href" : "none" //determine corresponding attribute to test for
 var allsuspects=document.getElementsByTagName(targetelement)
 for (var i=allsuspects.length; i>=0; i--){ //search backwards within nodelist for matching elements to remove
  if (allsuspects[i] && allsuspects[i].getAttribute(targetattr)!=null && allsuspects[i].getAttribute(targetattr).indexOf(oldfilename)!=-1){
   var newelement=createjscssfile(newfilename, filetype)
   allsuspects[i].parentNode.replaceChild(newelement, allsuspects[i])
  }
 }
}

replacejscssfile("oldscript.js", "newscript.js", "js") //Replace all occurences of "oldscript.js" with "newscript.js"
replacejscssfile("oldstyle.css", "newstyle", "css") //Replace all occurences "oldstyle.css" with "newstyle.css"
