Javascript - Change The Page Source Reference File Path

I have an Application that has a reference to a javascript file . Long story short, For lot of Reasons, i cannot change this js file nor can i change place where it is referred. So

Solution 1:

Maybe, you can try to use the holdready function of jquery like follows

$.holdReady( true );
$.getScript( "myplugin.js", function() {
   $.holdReady( false );
});

then you must looking for the script element that contains an attribute src like "FileIHaveFullControl.js" and remove it.

$("script").each(function(i, j){
    if($(this).attr("src").equals("corrupted file url"))
        $(this).remove(); 
});

most information on the jquery reference http://api.jquery.com/jquery.holdready/

Solution 2:

Assuming that you don't have access to the html file and thus you can't editing it (otherwise the question would make no sense), I'm affraid I have to inform you that a script src can only be set once. It's not possible to change it.

But it turns out that you can replace from the dom instead. I found this function on the web:

functioncreatejscssfile(filename, filetype){
 if (filetype=="js"){ //if filename is a external JavaScript filevar fileref=document.createElement('script')
  fileref.setAttribute("type","text/javascript")
  fileref.setAttribute("src", filename)
 }
 elseif (filetype=="css"){ //if filename is an external CSS filevar fileref=document.createElement("link")
  fileref.setAttribute("rel", "stylesheet")
  fileref.setAttribute("type", "text/css")
  fileref.setAttribute("href", filename)
 }
 return fileref
}

functionreplacejscssfile(oldfilename, newfilename, filetype){
 var targetelement=(filetype=="js")? "script" : (filetype=="css")? "link" : "none"//determine element type to create nodelist usingvar targetattr=(filetype=="js")? "src" : (filetype=="css")? "href" : "none"//determine corresponding attribute to test forvar allsuspects=document.getElementsByTagName(targetelement)
 for (var i=allsuspects.length; i>=0; i--){ //search backwards within nodelist for matching elements to removeif (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"
